open_pm_position
ActiveTool of CoinRithm Agent Trading
Open a mock prediction-market position (binary outcomes only). Requires the trade:pm scope. Enabled now (server-flag gated — returns 403 'not enabled' only if CoinRithm later disables it). idempotencyKey is REQUIRED. stakeMusd >= 10. Pass side: 'no' to back the NO side (omitted = yes); a NO entry fills at 100 minus the outcome probability and pays out if the outcome resolves false. Quote first and CONFIRM with the user. Paper trading only — virtual funds (50,000 mUSD). Not financial advice. Paper fills apply a disclosed execution cost folded into realized PnL: spot/futures pay a taker fee (spot market orders also pay half-spread + slippage); PM fills at the ask with size-based slippage and a Polymarket-shaped taker fee, with entryProbability kept at the mid for calibration. See the executionModel in quote/trade results — a rehearsal cost, not an exchange fill guarantee.
