Tendermint-RPC API

Supported methods for Alchemy Crypto.org Tendermint RPC API.

Alchemy Tendermint API

Here you will find a list of all the methods Alchemy supports for Tendermint.

​Official Tendermint Documentation​

There might be methods supported by Crypto.org nodes but not by Alchemy. See the full list of Tendermint API methods on the official documentation.

RPC Protocols

There are two RPC protocols that are supported for Alchemy Tendermint.

URI/HTTP

A REST like interface.
curl https://cro-croeseid.alchemyapi.io/your-api-key/tendermint/block?height=5

JSONRPC/HTTP

JSONRPC requests can be POST'd to the root RPC endpoint via HTTP.
curl --header "Content-Type: application/json" --request POST --data '{"method": "block", "params": ["5"], "id": 1}' https://cro-croeseid.alchemyapi.io/your-api-key/tendermint/

API Key

We've created an API key called your-api-key so you can easily copy and paste these sample requests above and below. However, you should replace your-api-key with your own API key when developing.

Arguments

Arguments which expect strings or byte arrays may be passed as quoted strings, like "abc" or as 0x- prefixed strings like 0x616263

Error Codes

Unlike direct Crypto.org nodes, Alchemy will return a 200response for every request served. This means even requests that resulted in an error will get back a 200 response and the corresponding error message. If the request was unable to be served by the nodes at all, users will receive a 500 response error code.

blockchain

Get block headers (max: 20) for minHeight <= height <= maxHeight. If maxHeight does not yet exist, blocks up to the current height will be returned. If minHeight does not exist (due to pruning), earliest existing height will be used.
At most 20 items will be returned. Block headers are returned in descending order (highest first).

Parameters

  • minHeight - integer, minimum block height to return
  • maxHeight - integer, maximum block height to return

Returns

Block headers, returned in descending order (highest first).

commit

Get commit results at a specified height.

Parameters

  • height - integer, height to return. If no height is provided, it will fetch commit information regarding the latest block. Default value = 0

Returns

Commit results. Canonical switches from false to true for block H once block H+1 has been committed, until then it's subjective and only reflects what this node has seen so far

validators

Get validator set at a specified height. Validators are sorted first by voting power (descending), then by address (ascending).

Parameters

  • height - integer, height to return. If no height is provided, it will fetch validator set which corresponds to the latest block. Default value = 0
  • page - integer, page number (1-based). Default value = 1
  • per_page - integer, number of entries per page (max: 100). Default value: 30

Returns

Commit results.
