TzStats provides a powerful Tezos API to access fully indexed raw data and statistics collected from the Tezos blockchain. Made and supported by Blockwatch Data. You may use this API free of charge and without limits for non-commercial projects. To inquire about commercial use send an email to license@blockwatch.cc.

This API reference provides information on all public API endpoints and the different schemes of calling them. Access to the API does not require authentication and we do not enforce rate limits right now, but we monitor usage and may apply limits later to guarantee fair usage for everybody.

The API supports three different endpoint flavors to access the same underlying data in different ways:

Calling the API

Our Tezos API is read-only at the moment, i.e. the only supported HTTP methods are GET, HEAD and OPTIONS. Query parameters must be properly URL encoded and appended as query arguments.

For high-speed high-volume access, always use the table API endpoints. Table and time-series endpoints stream data and have higher limits, that is, they immediately return response headers after accepting and validating a request and then stream rows or aggregated data points as they are fetched from the underlying database.

Transport Security

All our certificates are signed by LetsEncrypt Authority X3 certificate.

Available ciphers are

ECDHE-ECDSA-AES256-GCM-SHA384
ECDHE-ECDSA-CHACHA20-POLY1305
ECDHE-ECDSA-AES128-GCM-SHA256
ECDHE-ECDSA-AES256-SHA384
ECDHE-ECDSA-AES128-SHA256
ECDHE-RSA-AES256-GCM-SHA384
ECDHE-RSA-CHACHA20-POLY1305
ECDHE-RSA-AES128-GCM-SHA256
ECDHE-RSA-AES256-SHA384
ECDHE-RSA-AES128-SHA256

The API supports secure connections via TLS v1.3, v1.2 and v1.1 with Perfect Forward Secrecy based on Elliptic Curves and Diffie Helman key exchange. Insecure HTTP requests to port 80 are automatically redirected to HTTPS on port 443.

Tezos API Response Headers

All our API responses are tagged with an API version that’s included in the X-Api-Version HTTP header field as well as the Tezos network id and protocol.

Current TzStats Mainnet Response Headers

# API version
X-Api-Version:   v008-2021-02-10

# Tezos Network (chain id)
X-Network-Id:    NetXdQprcVkpaWU

# Tezos Protocol (protocol hash)

CORS

TzStats Data API supports cross-origin HTTP requests, commonly referred as CORS. This means that you can call the API using Javascript from any browser. Right now CORS support is limited to localhost and the tzstats.com domain. Send a request to tzstats@blockwatch.cc if you have an interesting use case and like to get whitelisted.

Rate Limits

We do not enforce limits on the number of calls or the amount of data you can query from the API. We do, however, use SPAM protection measures that limit the number of connection attempts and HTTP calls over short time-frames. Try to slow down your call rate if you start seeing 429 status codes. Be responsible with calls and retries, this API is a shared resource for everybody.

Data Formats

Regular JSON Objects

    "tz1XfAjZyaLdceHnZxbMYop7g7kWKPut4PR7",
    626158,
    152
  ]
]

Results are returned as Content-Type JSON (RFC 7159) or CSV (RFC 4180). Select either format by appending .json or .csv to the query path.

CSV files always include a header containing the requested column names in the requested order. Columns are separated by comma (ASCII 44, UTF-8 0x2C).

When downloading a CSV file you may add an optional filename query argument (ASCII only, 128 characters max, no path separators) which will be used in the Content-Disposition header. Suffix .csv isautomatically appended if missing.

JSON Bulk Arrays

Large JSON results such as lists and time-series use a more optimized (less verbose) formatting. Instead of regular JSON objects with named key/value pairs we use bulk arrays, i.e. two levels of nested JSON arrays without keys. An outer array contains result rows or datapoints. The inner arrays contain lists of columns. To control which columns are returned and their order use the columns query parameter.

Note: As we keep adding new fields to tables and time-series the default order of JSON bulk arrays may change over time. To ensure that our API always returns the field order you expect, use the columns query argument. The order of columns you specify is exactly the order that’s returned.

JSON Data Types

We use the following data types and encoding conventions throughout the API:
string unstructured ASCII/UTF-8 text
bytes binary data encoded
datetime UTC timestamps as UNIX milliseconds, e.g. 1536246000000 or ISO 8601/RFC3339 strings 2018-09-06T15:00:00Z
duration signed 64bit integers with second precision
boolean a binary value, either as string or number true (1) or false (0)
float64 an IEEE-754 64-bit floating-point number
int64 a signed 64-bit integer (Range: -9,223,372,036,854,775,807 through 9,223,372,036,854,775,807)
uint64 an unsigned 64-bit integer (Range: 0 through 18,446,744,073,709,551,615)
enum enumerable values expressed as strings, usually used for types
hash on-chain hashes encoded as base58-check strings
money monetary quantities are expressed as float64 with 6 decimal points (the Tezos coin unit precision); market endpoints use 5 or more decimal points depending on the fiat or crypto pairs

For efficiency reasons, timestamps in JSON bulk arrays are encoded as UNIX time at millisecond resolution. That is, value 0 represents Jan 1, 1970 00:00:00 UTC. Timestamps in explorer responses and CSV output are encoded according to RFC 3339 (2018-09-06T08:07:38Z) for convenience and human readability.

Timestamps in queries can be expressed in multiple ways:

Status Codes

The TzStats Data API responds with regular HTTP status codes in the 2xx range to indicate success, in the 4xx range to indicate client-side errors and in the 5xx range to indicate backend errors. The response body contains additional information encoded as JSON object.

Error Responses

API Error Response

{
  "errors": [
    {
      "code": 1007,
      "status": 400,
      "message": "incorrect request syntax",
      "scope": "StreamTable",
      "detail": "unknown column 'cycles'",
      "request_id": "BW-a935b7fedf6beefcedc94e539cfe320cc551c5b3",
    }
  ]
}

All error messages are JSON encoded. They contain fields numeric and human readable fields to help developers easily debug and map errors.

Fields Description
status int The HTTP status code, duplicated for convenience.
message string A textual representation of the error status.
scope string The name of the API call that has failed.
detail string A detailed text description of the error.
code int An internal error code.
request_id string Unique call id that helps us trace failed requests.

Explorer Endpoints

Explorer endpoints serve individual large JSON objects and a few related lists. JSON objects use the typical JSON key/value structure and you cannot limit the contents of objects (i.e. they are always sent in full). CSV format is not supported here.

Most explorer endpoints take different kinds of path arguments to define the object to return. This can be:

Some endpoints support a simple pagination scheme to walk lists of results (i.e. for related operations or accounts). To paginate append limit and offset, both are positive integers. Limit defaults to 20 and is capped to a maximum value of 100. Results are always sorted by row_id of the underlying table. Sort direction can be controlled by order (asc, or desc). If you require sorting by a different field, you have to do this client-side.

List Account Operations

GET https://api.tzstats.com/explorer/account/{hash}/operations

Lists operations sent from and to an account (defaults to all types and ascending order). This endpoint supports pagination with limit, offset and cursor. Use type to filter for a specific operation type (e.g. transaction), block (int64|hash) to lock a call to a specific block height or hash (hash is reorg-aware and throws an error when block has become orphan). To query for updates after a certain block use the optional argument since (int64|hash). To change the order of returned calls use the optional order (asc|desc) parameter. Use meta (boolean) to add optional account metadata.

List Managed and Created Contracts

GET https://api.tzstats.com/explorer/account/{hash}/contracts

Lists all contracts this account has originated. This endpoint has been renamed from ../managed.

List Account Ballots

GET https://api.tzstats.com/explorer/account/{hash}/ballots

Lists all voting ballots the account has sent. This applies to bakers only.

Bakers

Get a list of all active bakers, their current status and affiliation metadata. Optionally filter by status and country or get a random list of suggestions for a given account. This endpoint is supposed to be a simple to use listing feature for wallets and other dapps who like to enable delegation.

Filter Options

You can filter the baker list by the following criteria

Argument Description
status enum Filter by baker status public, private, closing, closed.
country enum Filter by baker country of operation (use ISO 3166-1 Alpha-2 country codes, that’s two uppercase letters like US, DE, FR)
suggest address Return a suggested list of bakers for the given address (see below)
cursor int Last baker id after which to continue listing, use for paging.
limit int Max number of results to return (max 100).
offset int Skip first N results, use for paging instead of cursor.

Baker Metadata

Bigmaps

Bigmaps are key-value stores where smart contracts can store large amounts of data. Values in bigmaps are accessed by unique keys. The TzStats bigmap index supports different key encodings: a hash (script expression hash), the binary representation of a key and the native typed version of a key. For convenience, all three variants are present in responses as key_hash, key_binary and key.

Types A bigmap is defined by a key_type and a value_type. While the key type is most often a simple type (int, string, bytes, address, etc), the value can have a complex type structure. Complex keys (using pairs) are represented as JSON primitive tree and a collapsed stringified version of such keys is returned in the optional key_pretty field. Values are represented in unboxed (decoded) form and optionally as original Michelson primitives.

Unboxing The API supports a mix of multiple representations for keys and values. Per default only decoded keys (as hash, binary, and native) and unboxed values are returned. Unboxing uses the types and annotations defined on contract origination to decompose Michelson primitives into nested JSON objects where annotations become JSON property names. Use the optional request parameter prim (bool) to include the native Michelson value representation (a tree of primitives).

Packed Data When keys or values are packed using the PACK instruction, an unpacked version can be obtained when using the optional unpack (bool) query argument. In this case two additional properties key_unpacked and value_unpacked are added to the result.

Metadata Each bigmap entry comes with a set of metadata that describes latest update time, block hash and height as well as the bigmap id and its owner. Bigmap ownership is 1:N, ie. a smart contract can own multiple bigmaps, but each bigmap has only one owner.

Pagination The Bigmap API support paginated queries for keys, values and updates using limit and offset.

Time-lock To query a bigmap at a certain point in time (ie. a specific block) use the optional query argument block (int64|hash) to specify a height or block hash. Hash is reorg-aware, ie. in case you execute a query on a block that becomes orphaned, the API returns a 409 Conflict error. To query for updates after a certain block use the optional argument since (int64|hash).

SECURITY WARNING

Unlike other on-chain data where values and ranges are predictable the contents of bigmaps are entirely user-controlled and unpredictable. IT MAY CONTAIN MALICIOUS DATA INTENDED TO ATTACK YOUR APPLICATIONS AND USERS! Be vigilant and sanitize all data before you process or display it.

Returns bigmap type description in Michelson JSON format, both for keys and values. Keys are simple scalar types and values can have a simple or complex type. JSON keys for bigmap type arguments now always follow the convention <order>@<name>@<container-type>, ie. they include an integer order number as first argument (starting at zero), followed by an optional @ symbol, an optional name extracted from type annotations and in case the type is a container like list, map or set another @ and the container type. JSON value contains a string with the michelson type name (if scalar) or a JSON object describing the nested type following the same naming conventions. Use prim (boolean) to embed original Michelson primitives for key and value type definitions.

Returns a list of operations in the corresponding block. Use limit, offset and/or cursor (all integers) to page through operation lists. Operations are sorted by row_id in ascending order. Cursor is the last row_id in sort order you have seen. Use order to switch between asc or desc order. Allows filtering operations by type using query filters. Use meta (boolean) to embed optional account metadata for all related accounts like senders, receivers, delegates.

The result contains information about all events that happen on-chain. Some of these events are signed operations with a proper operation hash, others are implicit events that have no corresponding representation, but are still required to correctly reconcile account balances and on-chain state/relationships. Important examples for implicit events are bake and unfreeze which change balances of bakers on their sub-accounts.

List Contract Calls

GET https://api.tzstats.com/explorer/contract/{hash}/calls

Returns calls (transactions) sent to the contract with embedded parameters, storage and bigmap updates. Use the optional prim (boolean) argument to embed Michelson primitive trees in addition to unboxed call data. To query calls until a specific block use the optional query argument block (int64|hash). Hash is reorg-aware, ie. in case you execute a query on a block that becomes orphaned, the API returns a 409 Conflict error. To query for updates after a certain block use the optional argument since (int64|hash). To change the order of returned calls use the optional order (asc|desc) parameter (defaults to ascending). Use the optional entrypoint (int64|string) argument to filter calls by entrypoint. This argument takes either an id value (eg. 7), a name (eg. “mint”) or the branch (eg. “RRR”). Use meta (boolean) to add account metadata.

Unboxed Call Parameters

Example call parameters.

// ...
"parameters": {
  "entrypoint": "default",
  "branch": "RRR",
  "call": "mint",
  "id": 7,
  "value": {
    //...
  },
  "prim": {
    // ...
  },
},
// ...

Call parameters are part of the call (operation) structure and contain the following properties:

Field Description
entrypoint string Named entrypoint into the smart contract, e.g. ‘default’ or ‘entry_00.
branch string Path of left (L) or right (R) branches to reach the entrypoint’s code in the Michelson code tree.
call string Name of the actaully called entrypoint. This is useful if parameters contain a call to default or root entrypoints and specify the real entrypoint by branching only.
id int64 Position of the entrypoint in the Michelson parameter tree.
value object Call parameters in order of type definition.
prim object Michelson JSON encoded representation of call parameters (hidden by default, enable with prim=true).

On-chain elections can be queried by proposal hash or sequence number. An election contains a complete set of data on a past or the currently ongoing (head) on-chain voting process, including up to four voting periods. Voting periods may be empty when no proposal has been published. Only the last voting period of the last election is open at eny point in time. Ballots represent the individual ballot operations sent by bakers during votes or the upvotes to a proposal during the first voting period.

Returns info about a single operation or a list of related operations. Because Tezos supports batch operations (multiple operations sharing the same hash), internal operations (created by smart contract calls in response to a transaction) and implicit events (state changes that do not have an operation hash) this endpoint always returns an array of operation objects. In many cases this array contains one element only. Use the optional prim (boolean) parameter to embed Michelson primitive trees with smart contract calls. Use meta (boolean) to add optional account metadata.

Table Endpoints

Generic Table Query

https://api.tzstats.com/tables/{table_code}.{format}?{args}

Tables store data in tabular form as a set of columns. Each column has a specified type and each row has a unique uint64 row_id. Empty values are represented as JSON null or empty strings. Tables can grow extremely large, so its good practice to use filters and the columns query argument to limit the result size. Table responses are automatically sorted by row_id. Use client-side sorting if a different sorting order is required.

Query Arguments

Tables support the following general query parameters.

Argument Description
columns optional Comma separated list of column names to return. Bulk array results will be ordered accordingly. Default is all defined columns for a table.
limit optional Maximum number of rows to return. Limited to 50,000, default 500.
cursor optional Id (row_id) of the latest result row returned by a previous call.
order optional Result order either asc (default) or desc, sorted by row_id.

To paginate result sets larger than the maximum limit, include row_id into the list of columns and use the last value of row_id as cursor in your next call. This will automatically apply an extra filter row_id.gt=cursor for ascending and row_id.lt=cursor for descending order. You can of course also apply the relevant row_id filter directly, without using cursor.

Query Filters

Filter Example

The example below filters blocks by time range from time.gte=2019-08-01 (inclusive) to time.lte=2019-08-31 (inclusive) and returns columns time and height. The same effect can be achieved with the range operator time.rg=2019-08-01,2019-08-31.

curl "https://api.tzstats.com/tables/block.json?columns=time,height&time.gte=2018-08-01&time.lte=2018-08-31&limit=50000"

To filter tables use filter expressions of the form <column>.<operator>=<arg>. Filters work on any combination of columns regardless of type. For arguments, type encoding rules of the column type apply. Filtering by multiple columns is similar to a logical AND between expressions. For simplicity and performance there are currently no OR expressions or more complex operators available. Comparison order for strings and binary is the lexicographical order over UTF8 (string) or ASCII (binary) alphabets.

Operator Semantics
=, .eq= Equal. Matches rows where column values match exactly the filter value.
.ne= Not equal. Matches rows where column values do not match the filter value.
.gt= Greater than. matches columns whose value is strictly greater than the filter value.
.gte= Greater than or equal. matches columns whose value is greater than or equal to the filter value.
.lt= Less than. matches columns whose value is strictly smaller than the filter value.
.lte= Less than or equal. matches columns whose value is strictly smaller than or equal to the filter value.
.in= Inclusion in list. matches columns whose value is equal to one of the filter values. Multiple values must be separated by comma.
.nin= Not included in list. matches columns whose value is not equal to one of the filter values. Multiple values may be separated by comma.
.rg= Range. matches columns whose value is between the provided filter values, boundary inclusive. Requires exactly two values separated by comma. (This is similar to, but faster than using .gte= and .lte= in combination.)
.re= Regexp. matches columns whose value matches the regular expression. Can only be used on string-type columns (not enum or hash). Non-URL-safe characters must be properly escaped.

HTTP Response

Field Description
row_id uint64 Unique row identifier.
cycle int64 Cycle this income relates to.
account_id uint64 Unique row_id of the baker account this income relates to.
rolls int64 Number of rolls (at snapshot block).
balance money A baker’s own balance, composed of spendable balance and frozen deposits plus frozen fees (at snapshot block). Note that frozen rewards do not contribute towards rolls, hence they are not part of balance here.
delegated money Delegated balance (at snapshot block).
n_delegations int64 Count of incoming non-zero delegations (at snapshot block).
n_baking_rights int64 Count of baking rights in this cycle.
n_endorsing_rights int64 Count of endorsing rights in this cycle.
luck money Absolute luck in coins, i.e. the amount of extra coins that can be earned because randomization allocated more rights than the fair share of rolls.
luck_percent float Relation between actual random rights allocated vs. ideal rights gainable by rolls. Neutral luck is 100%, lower values indicated less rights than fair share, higher values indicate more rights.
performance_percent float Effectiveness of a baker in generating expected rewards. Optimal performance is 100%. The value is lower when blocks or endorsements are missed, low value blocks/endorsements are published or the baker is slashed and higher when extra income was generated from stolen blocks or denunciations. NOTE: This value is not ratio scale nor interval scale. CANNOT be used as benchmark between bakers.
contribution_percent float Effectiveness of a baker in utilizing all rights assigned and contribute to consensus. Optimal contribution is 100%. The value is lower when blocks or endorsements are missed and higher when blocks are stolen. NOTE: This value is ratio scale. It can be used as benchmark for baker availability or participation in consensus. It is strongly correlated to generated income, but does not capture low priority blocks, endorsements or slashing.
n_blocks_baked int64 Number of blocks baked in this cycle.
n_blocks_lost int64 Number of blocks lost in this cycle.
n_blocks_stolen int64 Number of blocks stolen in this cycle.
n_slots_endorsed int64 Number of slots endorsed in this cycle.
n_slots_missed int64 Number of endorsement slots missed in this cycle.
n_seeds_revealed int64 Number of seed nonces revealed in this cycle.
expected_income money Total income expected based on endorsing and priority 0 baking rights.
expected_bonds money Total expected deposits based on endorsing and priority 0 baking rights.
total_income money Total sum of all income (note: due to losses, the actual true income may be smaller which is not reflected by this field alone).
total_bonds money Actual deposits (note: due to losses, the actual bonds that will later be unfrozen may be smaller).
baking_income money Total income from baking blocks.
endorsing_income money Total income from endorsing blocks.
double_baking_income money Total income from denouncing double baking.
double_endorsing_income money Total income from denouncing double endorsing.
seed_income money Total income from publishing seed nonces.
fees_income money Total income from fees.
missed_baking_income money Missed income from lost blocks.
missed_endorsing_income money Missed income due to missed endorsements.
stolen_baking_income money Extra income from stolen blocks.
total_lost money Total lost income due to denunciations or unpublished seed nonces. NOTE: This does not automatically reduce total_income above.
lost_accusation_fees money Lost fees due to a denunciation.
lost_accusation_rewards money Lost rewards due to a denunciation.
lost_accusation_deposits money Lost income due to a denunciation.
lost_revelation_fees money Lost fees due to an unpublished seed nonce.
lost_revelation_rewards money Lost block rewards due to an unpublished seed nonce.
address hash Account address base58check encoded.
start_time datetime Income cycle start time.
end_time datetime Income cycle end time.

Time-Series Endpoints

Generic Time-Series Query

https://api.tzstats.com/series/{table_code}.{format}?{args}

The time-series API is an abstraction over tables which allows for server-side aggregation of multiple result rows over time. Time-series are meant to be displayed as graphs with time on the x-axis and some aggregate value on the y-axis. Since the underlying data is still in tabular form all table filters work on time-series as well.

Note that this time-series API does not fill gaps. That means when the underlying table contains no data for a particular time interval, the corresponding time-series row will be missing. Clients should be prepared for this case and fill gaps if required.

Intervals between timestamps are equally spaced and can be controlled by the collapse query parameter, i.e. 1d means each interval contains 24 hours of aggregated data. Time-series data can contain fields of all supported numeric data types (e.g. no strings or binary data). The aggregation function is fixed by the semantics of the data type. This may either be a sum, a count, first, last, min, max or mean value.

On the free API tier historic access is restricted to 90 days.

List of supported time-series

Endpoint Time-Series Content
GET /series/block aggregated block data
GET /series/flow aggregated balances, freezer and delegation flows
GET /series/op aggregated operations data
GET /series/chain running total counters for on-chain operations, accounts and rolls
GET /series/supply running supply totals
GET /series/{exchange}/{market}/ohlcv OHLCV candles

Query Arguments

Time-series datasets support the following query parameters.

Argument Description
columns optional Comma separated list of columns you like to fetch. Bulk array results will be ordered accordingly. Default is all defined columns for a series.
collapse optional Aggregate numeric data over different sampling intervals. Supported values are 1m (default), 5m, 15m, 30m, 1h, 2h, 3h, 4h, 6h, 12h, 1d, 1w, 1M, 3Mand 1y.
order optional Return data in asc (ascending) or desc (descending) order. Default is asc.
limit optional Maximum number of aggregated results returned. Limited to 50,000, default 500.
start_date optional Start of the time range to query. See timestamps for syntax.
end_date optional End of the time range to query. See timestamps for syntax.

When only start or end date are provided, the other end of the range is deducted from collapse and limit. I.e. with collapse of 1d and limit of 30 you’ll get 30 days of data after start_date or before end_date. Called without any optional parameters a query defaults to the most recent 500 minutes (end_date=now, limit=500 and collapse=1m).

Query Filters

Time-series support the same filters used on tables with the same filter expressions of form <column>.<operator>=<arg>. Filters can be used on all table fields, including fields that are not part of the aggregated result such as addresses and type enums.

Changelog

Recent changes and additions to the TzStats Data API.

2021-02-10

A big deal of behind-the-scenes performance improvements went into this release, so that we are able to deliver the snappy response times you’re used to. We’ve started to prune irrelevant historic data from rights (unused bolck priorities) and snapshots (non-selected baker and delegator balances) to make querying relevant data faster.

We also reworked our smart contract data model, stripping less useful fields available elsewhere and adding new fields like detected interface standard and used Michelson features. When contract code is patched by a protocol upgrade we now add an implicit migration operation and update the stored representation of contract code as well. The previous version of the contract code is still available, either as part of the origination or the most recent migration operation.

This release adds support for Edo, namely Michelson extensions tickets, comb pairs and lazy storage (currently still exposed as bigmap on the API) as well as simple Sapling support (traking total Sapling supply and flows). Please reach out to tzstats@blockwatch.cc if you need additional Sapling or ticket support.

We decided to not remove deprecated operation listing endpoints because many people still use them and we found a way to optimize their performance.

DEPRECATION NOTICES

2020-06-24

To handle the surge in volume we’re optimizing a few of the most heavily used API endpoints. Our aim is to improve user experience and stabilty for everybody.

The most important change is that we begin migrating operation listings on explorer endpoints from embedded arrays inside accounts/blocks to stand-alone arrays. Both flavors will be available in parallel for a while. For high-speed high-volume access, consider using the table API endpoints. Table access is much faster since data is streamed and requires less calls due to higher limits.

As we keep adding new fields to tables and time-series the default order of JSON bulk arrays may change over time. To ensure that our API always returns the field order you expect, use the columns query argument. The order of columns you specify is exactly the order that’s returned.
