How this service works
Pay-per-call: JSON Schema validator
Output
Returns a structured JSON object indicating whether the input document passes or fails the provided schema, including a list of specific validation errors with paths and messages for each failed constraint.
Example use cases
API response contract check
“Before I process this API response, validate it against my OpenAPI schema — the payload is {"id": 123, "status": "active", "items": []} and the schema requires id to be an integer, status to be one of ['active','inactive'], and items to be an array.”
User-submitted form data validation
“A user just submitted a registration form — can you check if this JSON is valid against my user schema? The data is {"email": "bob@example", "age": -1, "username": ""} and I need to know every field that fails validation.”
CI pipeline schema regression test
“Run schema validation on this config JSON to make sure nothing broke — check {"timeout": 30, "retries": "three", "endpoint": null} against a schema that requires timeout and retries to be integers and endpoint to be a non-null string.”
Technical details
Endpoint
GEThttps://fiatdock.com/s/svc_dad44fa0-017c-4f9b-80bb-ba1e7cba7ae9?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-call JSON Schema validation without managing a dedicated validation library or service. Ideal for agents that sporadically need schema checks as part of a pipeline, API contract testing, or data quality gates, without the overhead of a persistent validator service.
Side effects
- Missing required 'input' body causes argument error billed as a call
- Malformed JSON in body returns parse error
- Schema draft version mismatch causes unexpected validation failures
- Tool name or params not matching the seller's MCP shape returns argument error
- Network timeout returns no validation result but call may still be billed
