  title: CoinRithm Agent Trading API
  version: "1.5.0"
  description: |
    Programmatic **paper-trading** surface for AI agents on CoinRithm.

    **Version note:** `info.version` (1.5.0) is the API contract version and is
    distinct from the npm package version (@coinrithm/mcp-trading 0.4.0). They
    are versioned independently; a package update does not imply an API change.

    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.

    **Rate limits.** Every key carries two budgets, enforced per key (not per
    IP): **120 requests/min** across all agent endpoints, and **20
    trade-writes/min** (order placement/cancel, futures open/close, PM open).
    Responses include `RateLimit-Limit`, `RateLimit-Remaining`, and
    `RateLimit-Reset` headers so an agent can pace itself without guessing;
    a `429` additionally carries `Retry-After` (seconds) — back off at least
    that long before retrying. Budgets are server-tunable, so always prefer
    the live headers over the documented defaults.

    **Execution ledger.** `/api/agent/*` responses include
    `X-CoinRithm-Ledger-Event-Id` and `X-CoinRithm-Ledger-Status` when the
    private action ledger records the call. Ledger writes are fail-open: paper
    trading still works if ledger persistence is temporarily unavailable.
    Quote/write bodies may include optional `agentTrace` metadata; GET calls may
    send equivalent `X-CoinRithm-Run-Id`, `X-CoinRithm-Decision-Id`,
    `X-CoinRithm-Strategy-Label`, and `X-CoinRithm-Confidence` headers.

    **Paper execution model.** Fills are not idealized: every spot and futures
    fill applies a deterministic, fully-disclosed cost (a taker fee on notional,
    plus spread + slippage on spot market orders), folded into realized PnL — so
    a flat round-trip is a small loss, not a free breakeven. Quote and order
    responses carry an `executionModel` object describing the assumptions
    (fee/spread/slippage bps, per-trade estimates, `fundingMode`). PM fills at
    the ask (mid + half the ingested bid-ask spread) with size/liquidity-based
    slippage and a price-dependent taker fee (Polymarket-shaped, ~1.8% near 50%,
    ~0 at the extremes), folded into `sharesMusd`; `feeBps`/`spreadBps` are
    positive and `slippageBps` scales with order size, while `entryProbability`
    stays the mid for calibration. This is a rehearsal cost model, NOT an
    exchange fill guarantee; funding, order-book depth, latency, and market
    impact are not modeled.

        Historical OHLCV candles for indicator/momentum strategies (RSI,
        moving averages, breakouts), keyed by UCID like the rest of the agent
        surface — call /api/agent/resolve first. `range` picks both the
        lookback and the per-candle resolution: 1H = 60×1-minute,
        1D = 288×5-minute, 1W = 672×15-minute, 1M = 720×1-hour,
        3M = 540×4-hour candles. Candles are oldest→newest with `t` in unix
        SECONDS. o/h/l/c are converted to `fiat` (default USD) at the nearest
        stored rate; `v` (volume) stays USD regardless of fiat. Pure market
        data, cached ~60s server-side. Requires scope `read`.

        `idempotencyKey` is REQUIRED for API-key callers and unique per intent:
        reusing it replays the ORIGINAL result with `idempotentReplay: true`
        (safe to retry a timed-out request with the same key — it will never
        double-execute). The key follows the order across its lifecycle, so a
        replay still resolves after a resting order fills or is cancelled.

      description: |
        Requires scope `trade:futures`. Provide `stopLossPrice` and/or
        `takeProfitPrice`: a positive number SETS that trigger (validated
        side-aware against the CURRENT mark and the position's liquidation
        price — long: liq < SL < mark < TP; short inverted), explicit `null`
        CLEARS it, an omitted field is left unchanged. Naturally idempotent —
        no idempotencyKey needed.

        Triggers are fired by the per-minute worker off the same mark feed as
        liquidation (liquidation always takes precedence). A fire closes the
        FULL position at mark with realized PnL (exitReason `stop_loss` /
        `take_profit`) — discover fills between polls via
        `GET /trades?updatedSince=...`.

      description: |
        Paper Execution Realism v1 cost disclosure. Paper fills apply a
        deterministic, fully-disclosed cost so simulated PnL reflects real
        trading friction (a flat round-trip is a small loss, not a free
        breakeven). This is a rehearsal cost model, NOT an exchange fill
        guarantee. Per venue:
          - spot/futures: a taker fee (`feeBps`) on notional, folded into
            realized PnL. Spot market orders also fill at an adverse price
            (half-spread + slippage); futures entry/exit spread/slippage is
            not modeled in v1.
          - PM: fills at the ask (mid + half the ingested bid-ask spread) with
            size/liquidity-based slippage and a Polymarket-shaped taker fee
            (~1.8% near 50%, ~0 at the extremes), folded into `sharesMusd`.
            `feeBps`/`spreadBps` are positive and `slippageBps` scales with
            order size; `entryProbability` stays the mid for calibration.
        Funding rates, order-book depth, latency, and market impact are not

        Pre-computed market-quality grade for a prediction market (the same
        builder the web event/hub cards use): a quality score + tiered
        liquidity/volume/spread + risk flags. Lets an agent gauge tradability
        without running its own analysis. Returned by get_market_context's
        relatedMarkets and by pm/quote.
