Convert JSON to Zod Schema API

What it does

JSON to Zod Schema converts JSON input into a Zod schema you can use in TypeScript projects. Send a raw JSON body, an uploaded JSON file, or a public JSON URL, and get back generated Zod code as either a downloadable .ts file, a pre-signed S3 URL, or a raw explain payload.

Use the mode query parameter to choose annotated, clean, or explain output. The strict option controls whether the generator applies strict schema behavior. For file-based and URL-based flows, you can also set output when the endpoint returns a downloadable file or S3 link.

The service accepts only non-empty JSON objects. URL-based endpoints require a publicly accessible resource that serves JSON or a .json file path, and file-based endpoints require an uploaded JSON file. The raw-body endpoint accepts application/json and also parses text/plain when it contains JSON.

Use JSON to Zod Schema when you need to bootstrap validation from sample payloads, document an API response shape, or turn an existing config object into reusable runtime validation.
