Generate JSON Schema from API Response

This example generates a JSON Schema (draft-07) from a typical REST API response. The pre-filled JSON represents a user object with nested address, array of roles, and array of post objects. Switch to Schema mode to see the inferred schema.

What You Get

The tool produces:

How to Use

  1. The example loads with a sample API response and Schema mode pre-selected
  2. Inspect the generated JSON Schema structure
  3. Copy the schema and use it with your validation library
  4. Replace with your actual API response to generate schemas for your endpoints

Real-World Pattern

REST APIs return structured JSON that maps cleanly to JSON Schema. Use the generated schema to validate API responses at runtime, document your API with OpenAPI/Swagger, or generate client-side types automatically.
