Generate Zod Schemas from API Response

This example generates Zod schemas with TypeScript type inference 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 Zod mode to see the generated schemas.

What You Get

The tool produces:

How to Use

  1. The example loads with a sample API response and Zod mode pre-selected
  2. Inspect the generated schemas and inferred types
  3. Copy the code and paste it into your TypeScript project (install zod first: npm install zod)
  4. Replace with your actual API response to generate schemas for your endpoints

Real-World Pattern

Zod schemas provide both runtime validation and compile-time type safety from a single definition. Use schema.parse(data) to validate API responses, form inputs, or any external data. The inferred types eliminate duplication between your validation logic and TypeScript interfaces.
