Step 3 of the quote → sign → submit BYOW flow. 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. ## Request fields | Field | Type | Required | Description | | ------------------- | ------ | ------------- | --------------------------------------------------------- | | `marketTicker` | string | Yes | Kalshi market ticker, e.g. `KXHIGHNY-26FEB19-T70` | | `side` | string | Yes | `YES` or `NO` | | `action` | string | Yes | `BUY` or `SELL` | | `amount` | number | BUY required | Buy amount in USDC (min 0.000001) | | `shares` | number | SELL required | Sell shares (min 0.000001) | | `userPublicKey` | string | Yes | Signing Solana wallet address | | `signedTransaction` | string | Yes | Base64-encoded signed transaction | | `quoteId` | string | Yes | Quote ID from `/kalshi/agent/quote` response | | `destinationWallet` | string | No | Destination wallet for received tokens | | `inAmount` | string | No | DFlow input amount from quote response (scaled integer) | | `outAmount` | string | No | DFlow output amount from quote response (scaled integer) | | `minOutAmount` | string | No | DFlow minimum output from quote response (scaled integer) | | `skillSlug` | string | No | Skill identifier for strategy logging | | `source` | string | No | Source tag for strategy logging | | `reasoning` | string | No | Strategy reasoning text (max 1000 chars) | ## Example ```bash theme={null} curl -X POST "https://www.aionmarket.com/bvapi/kalshi/agent/submit" \ -H "Authorization: Bearer YOUR_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "marketTicker": "KXHIGHNY-26FEB19-T70", "side": "YES", "action": "BUY", "amount": 10, "signedTransaction": "BASE64_SIGNED_TX", "quoteId": "quote_1713604800000_42", "userPublicKey": "8Yj7Dfp8oS3wkt2uP12xMz9VfF7ZzBv4qfB8Zbe8vXJ1", "inAmount": "10000000", "outAmount": "15384615", "minOutAmount": "14615384", "source": "sdk:kalshi-weather", "skillSlug": "kalshi-weather-trader", "reasoning": "NOAA forecast indicates edge" }' ``` ```python theme={null} result = client.kalshi_submit( market_ticker="KXHIGHNY-26FEB19-T70", side="YES", action="BUY", amount=10, signed_transaction="BASE64_SIGNED_TX", quote_id="quote_1713604800000_42", user_public_key="8Yj7Dfp8oS3wkt2uP12xMz9VfF7ZzBv4qfB8Zbe8vXJ1", in_amount="10000000", out_amount="15384615", min_out_amount="14615384", source="sdk:kalshi-weather", skill_slug="kalshi-weather-trader", reasoning="NOAA forecast indicates edge", ) order_id = result["orderId"] tx_sig = result["txSignature"] print(f"Order {order_id} | tx={tx_sig}") ``` ## Response ```json theme={null} { "orderId": "100001", "txSignature": "5Uj9xK2m...", "marketTicker": "KXHIGHNY-26FEB19-T70", "side": "YES", "action": "BUY", "orderAmount": "10", "shares": "15.384615", "orderStatus": 1 } ``` | Response field | Type | Description | | -------------- | ------ | --------------------------------------------------------- | | `orderId` | string | Primary key in `mk_kalshi_order` table | | `txSignature` | string | Solana transaction signature | | `marketTicker` | string | Echoed market ticker | | `side` | string | `YES` or `NO` | | `action` | string | `BUY` or `SELL` | | `orderAmount` | string | Order amount in USDC | | `shares` | string | Calculated order shares | | `orderStatus` | number | `1` = pending.
