How this service works
Validate the structure of an x402 payment payload before an agent signs or submits it.
Output
Returns a JSON object with an 'ok' boolean indicating overall pass/fail, an 'issues' array listing any detected problems, and a 'structural_valid' boolean confirming whether the payload is structurally well-formed.
Example use cases
Pre-flight check before gas spend
“Before I broadcast this Ethereum transaction, can you run a sanity check on the payload to make sure there are no structural errors or missing fields that would waste gas or get it rejected?”
Validate DeFi swap request body
“I'm about to submit this DeFi swap payload to the exchange — can you check it for any logical inconsistencies or formatting issues before it goes live?”
Catch errors in blockchain payload
“I put together this blockchain transaction payload manually and I'm worried I might have missed something — can you validate it and flag any problems before I try to submit it?”
Technical details
Endpoint
POSThttps://gateway.apiosk.com/crypto-sanity/validate/payloadWhen to prefer
Use this endpoint when you need a quick, cheap pre-flight check on a crypto payload before submitting it to a live blockchain or exchange endpoint — especially to catch structural errors, missing fields, or logical inconsistencies without spending gas or risking rejection downstream.
Side effects
- Malformed or unparseable request body returns validation error
- Missing required payload fields may result in structural_valid: false with issues listed
- Network timeout if gateway is unreachable
- Payment failure if insufficient USDC balance for x402 protocol
- Unexpected payload schema may produce unrecognized issues
