Frequently Asked Questions
What does JSON Schema validation check?
It checks structure rules such as required fields, data types, enum values, and numeric or string constraints defined by your schema.
Can I use this for API contract testing?
Yes. It is useful for validating request or response payloads before integrating with backend services.
Is my schema uploaded anywhere?
No. Validation runs entirely client-side in your browser.
