Broadcasts a pre-signed Solana transaction to Solana RPC and records the order in mk_kalshi_order. Also writes to mk_ai_agent_strategy_log and updates mk_ai_agent.sol_address. Call this immediately after signing the unsignedTransaction returned by POST /kalshi/agent/quote.

Notes

Agent-only endpoint. Requires Bearer API key in Authorization header.
Signature must be produced on client/agent side.
Server does not store or process private keys.
Transaction is broadcast directly to Solana mainnet RPC.
Order status is tracked via DFlow order-status API in a background cron.
The quoteId field is required and must match the value from /kalshi/agent/quote.
Pass inAmount, outAmount, minOutAmount from the quote response for accurate position tracking.
