Quickstart

Sign in, open a project, and create a key from its Solana page. The key is shown once, so store it in a secret manager or environment variable.

export OPENINFRA_API_KEY=sk_live_xxxxxxxxxxxx

Fetch the current slot using getSlot:

import { Connection } from "@solana/web3.js"; const conn = new Connection("https://rpc.sol.openinfra.sh", {  commitment: "confirmed",  httpHeaders: { "x-api-key": process.env.OPENINFRA_API_KEY! },}); console.log("Current slot:", await conn.getSlot());

Expected JSON-RPC response shape:

{ "jsonrpc": "2.0", "result": 312445981, "id": 1 }

Connect to the separate WebSocket endpoint and authenticate with either the x-api-key upgrade header or the verified api-key query parameter:

const key = process.env.OPENINFRA_API_KEY;const ws = new WebSocket("wss://ws.sol.openinfra.sh?api-key=" + encodeURIComponent(key)); ws.onopen = () => {  ws.send(JSON.stringify({    jsonrpc: "2.0",    id: 1,    method: "slotSubscribe",  }));}; ws.onmessage = (event) => {  const message = JSON.parse(event.data);  console.log(message);};

Use Yellowstone gRPC for filterable Solana account and transaction updates, or Datastream and Eventstream for OpenInfra topic streams.
