The crypto data wire, built from source.

That's a real, live connection to this page — not a screenshot. Full product is a real WebSocket too, not polling: auth happens over the first message, never in the URL, so your key never lands in a proxy access log. Subscribe to any of ~700+ USDT pairs, not just the majors.

const ws = new WebSocket("wss://free-api.news/v1/stream/prices");

ws.onopen = () => ws.send(JSON.stringify({ type: "auth", apiKey: "YOUR_API_KEY" }));

ws.onmessage = (event) => {
  const msg = JSON.parse(event.data);
  if (msg.type === "connected") {
    ws.send(JSON.stringify({ type: "subscribe", symbols: ["BTC"] }));
  }
  if (msg.type === "tick") {
    console.log(msg.symbol, msg.price); // "BTC" "64401.12000000"
  }
};
