How this service works
Call when an agent needs a limited JSON Schema draft-06 check. Dialects disagree on exclusive bounds and format. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/check-schema-draft-06 first.
Output
Returns a JSON object indicating whether the data value is valid against the provided JSON Schema draft-06, along with any validation errors describing which constraints failed, particularly around draft-06-specific semantics like exclusiveMinimum/exclusiveMaximum as booleans and format keyword handling.
Example use cases
API payload schema compliance check
“I need to verify that this API response payload is valid against my draft-06 schema before I pass it downstream — the schema uses exclusiveMinimum and format keywords, here's the schema and the data to check.”
Form input validation against schema
“Can you validate this user-submitted JSON form data against my draft-06 schema? I want to know if it passes or which fields fail, especially where I'm using exclusiveMaximum constraints.”
CI pipeline schema regression test
“Run a draft-06 schema check on this JSON value for me — I want to make sure my data still conforms to the schema after I updated the exclusive bounds.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/check-schema-draft-06?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need draft-06 JSON Schema validation, especially when your schema relies on draft-06-specific behavior such as exclusiveMinimum/exclusiveMaximum as boolean flags rather than numeric values, or when you need format keyword validation under draft-06 semantics. The free sandbox endpoint POST /v1/sandbox/check-schema-draft-06 should be tried first; use this paid endpoint when the sandbox is unavailable or rate-limited.
Side effects
- Schema or data value missing — returns error if required fields are absent
- Schema is not valid JSON or not draft-06 compatible — may return a parse or dialect error
- Data value exceeds 20,000 character limit — request rejected
- Dialect ambiguity around exclusive bounds or format keywords may produce unexpected results
- Network timeout or service unavailability returns HTTP 5xx
