Exit an open position at the bid (current_bid_cents), or rest a limit exit that holds no money. No bid: a market sell cannot. A closed trade answers its terminal state. route=best may split: fills lists each leg. route=kalshi sells at Kalshi's bid. contract_note on every exit of a non-Kalshi fill. dry_run=true sells nothing (a limit exit shows crosses_now). Selling is never gated by a membership. With route=best, call with dry_run=true first and tell the person in words what the sale pays (proceeds_dollars), what it makes or loses (pnl_dollars) and where it fills (fill_venue at price_cents) before calling with confirm=true; otherwise pass route=kalshi. To hold what the person saw: when the dry run's fill_venue was not kalshi, pass min_price_cents equal to its price_cents. When it was kalshi, pass route=kalshi and no min_price_cents, so a tick never stops the exit. confirm=true and a fresh idempotency_key, except dry_run. live=true sells on Kalshi. poly_intl=true sells on Polymarket International (not US). Pass one. Default is paper. This server places paper trades only: a call with live or poly_intl is refused (live_not_hosted).
