}Place a batch of signed orders (max 10)
Submit up to 10 EIP-712-signed orders in one request. Orders are processed sequentially in array order with independent per-order outcomes — one rejected order never aborts the rest, and there is no all-or-nothing atomicity. Each entry is validated, balance-locked, and matched exactly as a single POST /api/orders/place. Per-wallet monetary limits (KYC deposit tier, responsible-gambling, partner trade caps) accumulate across the batch, so a batch can never admit more exposure than the same orders sent one at a time. Rate limited at 5 req/sec per wallet (up to 50 orders/sec). KYC deposit-tier gating applies, same as single place. Business rejects (bad signature, insufficient funds, …) come back as per-entry REJECTED results with HTTP 200; infrastructure failures (matcher / verifier / DB unavailable) fail the whole request with a 5xx. Every forwarded entry carries a clientOrderId (the server mints one when you omit it) so a 5xx is safe to retry — replays return the already-committed result via idempotency instead of placing duplicates.

}Authorizations
Partner / integrator key — format ps_live_<keyId>_<secret>. Issued by PredictStreet ops on request; never self-service. Never ship to a browser. multi_wallet partners must additionally send X-User-Wallet: 0x<40-hex> on every authenticated request to declare the acting wallet. See the API keys guide for scope taxonomy, partner kinds, rate limits, and rotation procedure.
Headers
Required for multi_wallet partners on every authenticated request; ignored for single_wallet. Declares the acting end-user wallet for this request — drives KYC checks, balances/positions/orders attribution, rate-limit buckets, and audit. Lower-cased server-side. Missing on a multi_wallet key → 401 api_key_user_wallet_required; malformed → 401 api_key_user_wallet_invalid. The on-chain CTFExchange/Vault contracts still verify EIP-712 signer ↔ vault binding, so loosening API-layer attribution is safe by construction.

Body
1–10 orders, each identical in shape to the single POST /api/orders/place body. Processed sequentially in array order.

Response
Per-order results, aligned to the request orders[] by index. Inspect each entry's success flag and status — a 200 batch can still contain REJECTED entries.
Server-side order id (UUID). Empty string when status=REJECTED.
Lifecycle state at the moment of response. Note: a 200 response may carry status=REJECTED together with a populated code / message — partner SDKs MUST inspect the body, not just the HTTP code (audit M5).
PENDING, OPEN, FILLED, CANCELLED, REJECTED, EXPIRED, SETTLEMENT_FAILED Cumulative quantity filled at response time (decimal string).
quantity - filledQty (decimal string).
Synchronous fills produced by IOC/FOK or aggressive LIMIT orders.

true when the order was accepted (status ≠ REJECTED); false for a per-order business reject. Convenience flag over status.
Reject reason code (insufficient_balance, invalid_amounts, market_not_open, bad_signature, order_signed_with_floor_notional, position_limit_breached, …). Present when status=REJECTED. For order_signed_with_floor_notional the response body also carries a details object with signedMakerAmountWei + expectedCeilMakerAmountWei so the SDK can re-sign without recomputing the CEIL formula — see /errors/codes#order_signed_with_floor_notional-diagnostic-hints.
Human-readable explanation; pairs with code.
Echo of the request clientOrderId (when supplied). Lets MM partners correlate the server-issued orderId to their own client-side handle without a follow-up GET /api/orders/{id}. Present on every shape (success, REJECTED, idempotent replay) when the request carried one. Also echoed on the events.order_placed and events.order_cancelled WS frames.
