Schema Source by Tabstack

About

Obtain the JSON Schema for any webpage by simply entering its URL. You will receive a fully functional schema formatted as JSON Schema, a Zod object, or a Pydantic model, which can be directly integrated into your validation or extraction code. Schema Source automatically learns the URL patterns of each website, ensuring quick and consistent results across pages with similar structures. Each generated schema also functions as an API endpoint. By requesting the same URL with JSON content negotiation, you receive the cached schema instantly without needing an API key. This free service is provided by the team responsible for Tabstack, with support from Mozilla.
