}Funds a quote gaslessly with a signed Permit3 authorization.
target.quoteId names the quote, each permit3.permits[] entry names the quote’s execution.vault as its account, and signature is the top-level EIP-712 signature over the Permit3 payload. The first submission answers 202 with a gasless job; resending the same signature returns the existing job with 200.
Requires x-api-key. Partner pricing, attribution, and enabled features are tied to the key. Without a key the gateway answers 403 with a plain JSON body ({"Message": "User is not authorized ..."}); a key that is unknown, revoked, or not enabled for v1 answers 401 invalid-api-key. No requests-per-second quota is published. Handle 429 and honor Retry-After when present.
Examples use real mainnet token and contract addresses with placeholder wallets, hashes, signatures, and IDs.Authorizations
Body
application/json
Response
Existing job for the same signature and target.
