Market Data Overview

Openfish market data is public unless it is account-specific. Agents should use public market data for discovery and only use authenticated endpoints for private orders, trades, balances, and account state.

Current price endpoints read the in-memory CLOB order book at request time. Historical price endpoints read persisted snapshots; production snapshots are written every 300 seconds. Topic endpoints such as /browse/topics/world-cup/games are discovery payloads and may be cached, so use token-level REST or /ws/market for current prices.
