https://api.nightcobbler.com/v1/schema-extract

Structured extraction to YOUR schema: POST a URL and a JSON Schema, get back JSON with exactly the fields you named. Reads the data pages already publish for machines (JSON-LD/schema.org, OpenGraph, Twitter cards, meta) and conforms it to your types — product price, currency, SKU, brand, rating, author, dates. Validated before it returns: a result that does not match your schema is an error, and errors are free.
