WebSocket /ws

Real-time stream. On connect you receive a snapshot with every tracked symbol, then update messages whenever prices change. Send {"type":"subscribe","symbols":["BTC","ETH"]} to narrow the stream.

const ws = new WebSocket("wss://crypto-ai-prices.fly.dev/ws");

ws.onmessage = (e) => {
  const msg = JSON.parse(e.data);
  if (msg.type === "snapshot") console.log("initial prices", msg.prices);
  if (msg.type === "update")   console.log("tick", msg.prices);
};

// Optional: limit to specific symbols
ws.onopen = () => ws.send(JSON.stringify({ type: "subscribe", symbols: ["BTC", "ETH"] }));

Free tier vs real-time

Unauthenticated requests see a 15-second delayed feed. Real-time access is gated by an API key passed in the X-API-Key header (or ?apiKey= on WebSocket). The paid tier is in private beta — join the waitlist if you need it.

CURL

curl -H "X-API-Key: YOUR_KEY" https://crypto-ai-prices.fly.dev/api/prices

Limits & fair use

No hard rate limit today. Be reasonable — if you need sustained multi-hundred-req/sec, grab a key.
CORS is wide open. You can call every endpoint from a browser.
Data comes from public exchange feeds. We don't invent numbers, and we don't guarantee them — use at your own risk.
If we have to rate-limit you, we'll return 429 with a Retry-After header.
