@stacks/blockchain-api-client

The @stacks/blockchain-api-client library provides a robust interface for interacting with the Stacks Blockchain API by offering type-safe methods to access REST and WebSocket endpoints.

The client includes automatically generated HTTP API methods, comprehensive Schemas for Clarity smart contract values, and a WebSocket client for real-time data streaming.

import { AccountsApi } from '@stacks/blockchain-api-client';

const accounts = new AccountsApi(apiConfig);

await accounts.getAccountTransactions({
  principal: 'ST000000000000000000002AMW42H',
});

Using WebSockets

import { connectWebSocketClient } from '@stacks/blockchain-api-client';
const client = await connectWebSocketClient('ws://api.hiro.so/');
const sub = await client.subscribeAddressTransactions(contractCall.txId, event => {
  console.log(event);
});

await sub.unsubscribe();
