Stream prices over WebSocket

Connect to wss://chainpulseai.polsia.app/ws/prices and receive price updates as they happen — no polling, no rate limits.

// JavaScript example
const ws = new WebSocket('wss://chainpulseai.polsia.app/ws/prices');

ws.onmessage = (event) => {
  const { type, data } = JSON.parse(event.data);
  if (type === 'prices') {
    data.forEach(p => console.log(p.chain, p.price));
  }
};

Sub-100ms Latency
In-memory cache with 20s TTL. CoinGecko fetches run in the background, your requests never wait.
🌍
Global CDN
Served from multiple providers with failover. CoinGecko powers price data — no API keys needed.
📡
REST + WebSocket
GET /api/prices for snapshots, ws:// for real-time streaming. Both return identical JSON schemas.
🛡️
Graceful Degradation
Stale cache served when upstream is down. 503 only when both live and cache are unavailable.
