Turn any web page into JSON

Name the fields you want in plain English. We fetch the page, an AI model extracts the fields, and a second model checks every value against the page. You get typed JSON plus a confidence score for each field. No selectors, no subscription.

One per line: name: type — description. Types: string, number, boolean, url, string[]
Free: 5 extractions a day. No signup.

{
  "url": "https://books.toscrape.com/catalogue/a-light-in-the-attic_1000/index.html",
  "fields": {
    "title": "string",
    "price": "number — price in GBP",
    "in_stock": "boolean",
    "rating": "number — star rating 1-5",
    "description": "string — one sentence summary"
  },
  "many": false
}

Typed, schema-valid output

Output is constrained to your schema: numbers come back as numbers, missing values as null. You never get malformed JSON.

Every field verified

Each value is checked against the page for invented, misplaced or badly formatted data. Doubtful results are automatically re-run on a stronger model.

Records or lists

Pull one record from a product page, or every item from a listing, search result or feed, in a single call.

Pay for what you use

Credits are metered on actual model tokens. Failed fetches and failed extractions are refunded automatically.

One request

Same call from your code, a cron job, or an AI agent. Full reference in the API docs.

Is it the right tool for you?

We don't render JavaScript or rotate proxies yet, so single-page apps and heavily protected sites may not work. For those, see our comparison of scraping APIs: Firecrawl, ScrapingBee and Zyte handle them well.
