How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with an 'ok' boolean indicating pass/fail, an 'errors' array listing any validation issues found, an 'error_count' integer, a 'schema' identifier string (delx/util-json-schema-quickcheck/v1), and a 'note' clarifying this is a quickcheck rather than full draft-2020-12 validation.
Example use cases
Pre-flight API payload validation
“Before I send this user registration payload to the backend, can you check it against our user schema and tell me if there are any validation errors I need to fix?”
Agent tool output conformance check
“My agent just produced this JSON response — can you validate it against the expected output schema and list any fields that don't conform?”
Data pipeline schema gate
“I have a batch of JSON records coming in and I want to spot-check this one sample against our canonical schema to see if it would pass validation — can you run that check and show me any errors?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/json-schema-quickcheck?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, cheap ($0.002 USDC), no-signup schema validation check and full draft-2020-12 compliance is not required. Ideal for agents that need to gate-check JSON payloads programmatically without spinning up a local validator library. Prefer alternatives if you need complete JSON Schema draft-2020-12 compliance, detailed error paths, or bulk batch validation.
Side effects
- Malformed or non-object 'schema' field causes request rejection
- Malformed or non-object 'instance' field causes request rejection
- Payment failure via x402 protocol blocks request
- Quickcheck does not cover all draft-2020-12 keywords — complex schema features may not be evaluated
- Network timeout returns no result
