  title: CoinRithm Agent Trading API
  version: "1.1.0"
  description: |
    Programmatic **paper-trading** surface for AI agents on CoinRithm.

    All trading here is simulated: a 50,000 virtual-mUSD paper account, cash coin
    `USDT` (coinId `825`). Nothing touches real money or a real exchange. **Not
    financial advice.**

    Authenticate every request with a personal API key (`crk_live_…`) minted in
    your CoinRithm profile, presented as `Authorization: Bearer crk_live_…`
    (or the `X-API-Key` header). Scope gates restrict actions:
      - `read`           — reads + quotes
      - `trade:spot`     — place/cancel spot orders
      - `trade:futures`  — open/close mock futures
      - `trade:pm`       — open mock prediction-market positions

    NOTE: `POST /futures/open` and `POST /pm/open` are additionally server-flag
    gated; they are enabled now and return 403 ("… not enabled") only if
    CoinRithm later disables them.
