Not a REST call: this is the WebSocket handshake. Connect to the URL below and the exchange answers 101 Switching Protocols; everything after that is frames, not requests.

Public: no key, no signature.

Every trade on the pairs you name, as it prints.

Subscribe with one frame after connecting:

{ "Method": "subscribe", "CurrencyPairs": ["BTC_USDT", "ETH_USDT"] }

Each frame is acknowledged with {"Result":"Subscribed"}. Frames pushed to you:

{
  "dealId": "e2cd407c-28c8-4768-bd73-cd7357fbccde",
  "dealDateUtc": "2026-08-27T09:15:42.117Z",
  "currencyPairId": "BTC_USDT",
  "price": 64180.5,
  "volume": 0.0125,
  "isBuy": true
}

isBuy is the taker's side. The tape is anonymous: counterparties, order ids and fees are not published on it — read your own fills from /user-deals or GET /api/user/deals.
