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`. ## OpenAPI ````yaml /api-reference/openapi.json post /api/me/positions/op-submit openapi: 3.1.0 info: title: PredictStreet API description: >- Client-facing HTTP API for the PredictStreet prediction-market platform. **Partner kinds.** Every authenticated endpoint resolves a request's *effective wallet* from the partner row. `single_wallet` partners bind to one `associatedWallet` set at creation. `multi_wallet` partners declare the actor on every request via an `X-User-Wallet: 0x<40-hex>` header.

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. schema: $ref: '#/components/schemas/EthereumAddress' example: '0x1234567890abcdef1234567890abcdef12345678' schemas: VaultOpSubmitDto: type: object properties: signedOpId: type: string description: >- Operation id (UUID) returned by the co-sign endpoint (`/api/vault/{split,merge,convert}-signature`). example: 6ce7d9a4-3b85-4f31-9b7e-c2c2f3a5e7c4 ownerSig: type: string pattern: ^0x[0-9a-fA-F]+$ description: User's EIP-712 signature over the co-sign `digest`, 0x-hex. backendSig: type: string pattern: ^0x[0-9a-fA-F]+$ description: >- Backend co-signature returned by the co-sign endpoint, 0x-hex.
