How this service works
ForgeKit JSON Schema validation
Output
Returns a structured response indicating whether the JSON object is valid against the provided JSON Schema, along with any validation errors or constraint violations when the object fails.
Example use cases
API response contract check
“Validate this API response against our expected schema before we process it — the response is {"id":"123","status":"active"} and the schema requires id to be a string and status to be one of active, inactive, or pending.”
User input pre-submission guard
“Before I submit this form data to the backend, check that it satisfies our user registration schema — the data is {"email":"user@example.com","age":17} and the schema requires email as a valid string and age as an integer of at least 18.”
CI pipeline schema conformance check
“I need to verify that this config object {"timeout":5000,"retries":3,"mode":"strict"} matches our deployment config schema, which requires timeout and retries to be integers and mode to be either strict or lenient.”
Technical details
Endpoint
POSThttps://useforgekit.dev/api/v1/json/validateWhen to prefer
Choose this endpoint when you need a quick, pay-per-use JSON Schema validation call without spinning up your own schema validation library, especially in serverless or agent pipelines where adding dependencies is costly. Ideal when you already have a JSON Schema definition and just need to assert conformance on an object at runtime.
Side effects
- Invalid or malformed JSON Schema provided — returns an error indicating the schema itself could not be parsed
- Missing required fields in the request body (json or schema) — returns a 400-level error
- JSON object or schema exceeds size limits — returns payload too large error
- Network or server error — returns 5xx response
