info:
  title: Prediction Market API (Beta)
  description: >-
    Unified **beta** prediction market API for Kalshi and Polymarket — markets,
    events, full historical trades and candlesticks, orderbooks, crypto up/down
    windows, and Polymarket wallet analytics. Read/market-data only.


    **Auth:** pass your Data API key in the `x-api-key` header.


    **Conventions:** response bodies use camelCase. Query params are snake_case
    (camelCase aliases accepted where noted).


    **Caching:** SWR endpoints may set `X-Cache` (`HIT` | `HIT-STALE` | `MISS`).
    Busy backends may return `503` with `SERVICE_BUSY`.


    **Realtime:** join `pm:*` rooms on
    `wss://datastream.solanatracker.io/{apiKey}` (same Datastream hub as other
    products — see Datastream → Prediction Markets).
