}Funds a deposit address gaslessly with a signed ERC-3009
transferWithAuthorization. target.depositAddress must equal authorization.to. The first submission answers 202 with a gasless job; resending the same signature returns the existing job with 200.
No API key is required: Circle Gateway operations are open so that any wallet or relay can create and fund a deposit address. A supplied key that is unknown, revoked, or not enabled for v1 is still rejected with 401 invalid-api-key, so send no key rather than a wrong one. 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.Headers
Optional. A key that is unknown, revoked, or not enabled for v1 is rejected with 401.
Body
application/json
Response
Existing job for the same signature and target.
