Frequently Asked Questions
What is JSON Schema?
JSON Schema is a vocabulary that lets you annotate and validate JSON documents. It defines the expected structure, data types, required fields, and constraints for your JSON data.
Which JSON Schema drafts are supported?
The tool supports Draft 4, Draft 6, Draft 7, and Draft 2020-12. It auto-detects the draft from your schema's $schema keyword or lets you select one manually.
Can I validate API responses with this tool?
Yes. Paste the JSON Schema from your API specification (e.g., from an OpenAPI document) and the actual API response to verify that the response conforms to the expected format.
