abci_info - Cosmos

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

Returns information about the ABCI application running on this node — the application name, version, and current app state hash. For Cosmos Hub, this returns gaia-specific info.

Parameters

None

Request Example

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

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

import requests
import json

url = "https://go.getblock.io/<ACCESS-TOKEN>/"

payload = json.dumps({
    "jsonrpc": "2.0",
    "method": "abci_info",
    "params": [],
    "id": "getblock.io"
})

headers = {
    'Content-Type': 'application/json'
}

response = requests.post(url, headers=headers, data=payload)
print(response.text)

use reqwest::Client;
use serde_json::json;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = Client::new();

    let payload = json!({
        "jsonrpc": "2.0",
        "method": "abci_info",
        "params": [],
        "id": "getblock.io"
});

    let response = client
        .post("https://go.getblock.io/<ACCESS-TOKEN>/")
        .header("Content-Type", "application/json")
        .json(&payload)
        .send()
        .await?;

    let result: serde_json::Value = response.json().await?;
    println!("{:#?}", result);

    Ok(())
}

SDK Integration

import { Tendermint37Client, HttpClient } from '@cosmjs/tendermint-rpc';

const httpClient = new HttpClient('https://go.getblock.io/<ACCESS-TOKEN>/');
const client = await Tendermint37Client.create(httpClient);

// CosmJS exposes typed methods on the client (e.g. client.status(), client.block()).
// For raw access to any RPC method:
const result = await httpClient.execute({"jsonrpc": "2.0", "id": "getblock.io", "method": "abci_info", "params": []});
console.log(result);

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

response = requests.post('https://go.getblock.io/<ACCESS-TOKEN>/', json={
    'jsonrpc': '2.0',
    'id': 'getblock.io',
    'method': 'abci_info',
    'params': []
}})
print(response.json())
