block_results - Cosmos

Example code for the block_results JSON-RPC method. Complete guide on how to use block_results JSON-RPC in GetBlock Web3 documentation.

Returns the results of all transactions executed in a block — ABCI codes, gas used, events emitted, and per-transaction data. This is where event-driven indexers extract structured information about what happened in a block.

Parameters

Parameter

Type

Required

Description

height

integer

Block height (decimal). Defaults to the latest block if omitted

Request Example

# JSON-RPC over HTTP POST (canonical)
curl --location --request POST 'https://go.getblock.io/<ACCESS-TOKEN>/block_results' \
--header 'Content-Type: application/json' \
--data-raw '{
    "jsonrpc": "2.0",
    "method": "block_results",
    "params": {
        "height": 23456789
    },
    "id": "getblock.io"
}'

# URI over HTTP GET (alternate, for simple methods)
curl --location --request GET 'https://go.getblock.io/<ACCESS-TOKEN>/block_results?height=23456789'

import requests

// CosmJS exposes typed methods on the client (e.g. client.status(), client.block()).
// For raw access to any RPC method:

console.log(result);

# cosmpy wraps Cosmos REST / gRPC. For raw CometBFT RPC access, use requests.
