Version: 0.0.2 True Markets Market Data WebSocket

Overview

This API streams real-time market data over a single WebSocket connection. Clients subscribe to one or more topics and receive batched price candles, trending assets, surging assets, and weighted reference prices as they update.

Topics

Subscribe to specific topics, or to the all wildcard alias to receive every stream:

• price_candles — OHLC price candles
• trending_assets — trending assets
• surging_assets — surging assets
• reference_prices — weighted reference prices
• all — wildcard alias; receive all of the above

all is a subscription convenience, not a stream of its own. Every pushed message carries the concrete topic it belongs to in topics (e.g. ["price_candles"]), even when delivered to an all subscriber. Because all is a wildcard, unsubscribing an individual topic while subscribed to all has no effect — to drop a single topic, subscribe to explicit topics and unsubscribe them individually.

Authentication

All channels are public — no API key, signature, or other credentials are required.

Numeric Precision

Prices, market caps, and other numeric values are returned as strings to preserve full decimal precision and avoid floating-point rounding.
