Crypto.com price feed

Global exchange. Streamed via the book channel (100ms). Every Crypto.com quote appears in ticker:<SYMBOL> messages with "ex":"cryptocom".

Only Crypto.com quotes

const ws = new WebSocket("wss://aeonfeed.com/ws?subscribe=ticker:BTCUSDT,ticker:ETHUSDT");
ws.onmessage = (e) => {
  const msg = JSON.parse(e.data);
  if (msg.type !== "ticker" && msg.type !== "snapshot") return;
  const quotes = (msg.data ?? []).filter((q) => q.ex === "cryptocom");
  for (const q of quotes) console.log(msg.s, q.b, q.a);
};

Crypto.com native format → Aeon format

What Crypto.com actually sends for BTC/USDT, captured from its public WebSocket, and the normalised quote you receive from Aeon Feed. Depth arrays are trimmed for readability.
