}Broadcast a co-signed split/merge/convert without paying gas
Takes the signedOpId from a prior co-sign call plus the user + backend signatures, reads the authoritative op parameters stored with that co-sign (not from this request), and queues the split / merge / convert transaction for the platform to broadcast gaslessly. Returns { jobId, status }; poll GET /api/me/positions/op-submit/:jobId until the job confirms.
Failures: 404 op_not_found; 400 op_not_pending / op_expired / unsupported_op_kind.

}Authorizations
Partner / integrator key — format ps_live_<keyId>_<secret>. Partner keys are issued by PredictStreet; a user can also create keys bound to their own wallet from their account settings in the web app. 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.
^0x[a-fA-F0-9]{40}$"0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb3"
Body
Operation id (UUID) returned by the co-sign endpoint (/api/vault/{split,merge,convert}-signature).
"6ce7d9a4-3b85-4f31-9b7e-c2c2f3a5e7c4"
User's EIP-712 signature over the co-sign digest, 0x-hex.
^0x[0-9a-fA-F]+$Backend co-signature returned by the co-sign endpoint, 0x-hex. Send it back as received — the platform does not keep it with the pending op.
