How this service works
Call when an agent needs a limited JSON Schema 2019-09 check. Dialects disagree on exclusive bounds and format. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/check-schema-2019-09 first.
Output
A JSON response indicating whether the provided value conforms to the given JSON Schema 2019-09 schema, including any validation errors or violations found during the check.
Example use cases
API payload schema compliance check
“I need to validate this API response payload against our 2019-09 JSON Schema — the schema uses exclusiveMaximum and format keywords, and I want to know if the payload is compliant before we process it.”
Exclusive bounds dialect verification
“Can you check if the value {"score": 100} passes this 2019-09 schema that uses exclusiveMaximum: 100? I want to make sure the dialect handles exclusive bounds correctly.”
Developer schema regression testing
“Run a 2019-09 schema check on this JSON string against my schema definition — I'm testing whether our new data model still conforms to the draft 2019-09 rules before we ship.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/check-schema-2019-09?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need JSON Schema Draft 2019-09 dialect validation, particularly when exclusive bounds (exclusiveMinimum/exclusiveMaximum) or format keyword behavior under 2019-09 semantics matters. Prefer the free sandbox POST /v1/sandbox/check-schema-2019-09 first; use this paid endpoint when the sandbox is unavailable or for production-grade validation at $0.008 USDC per call.
Side effects
- Value or schema missing from request body returns an error
- Schema string exceeds 20,000 character limit results in rejection
- Malformed JSON schema causes parse error
- Dialect-specific format or exclusive bounds edge cases may differ from other draft behaviors
- Network timeout or service unavailability returns HTTP error
