What you send and get
| Field | What it does |
|---|---|
urls | Up to 50 URLs a request, or discover_from a seed URL to find up to 50 pages first. |
schema | A JSON Schema object, or a flat map of field names to descriptions. |
css_schema | Optional selectors. The fields they fill are free, and only the empty ones go to the LLM pass. |
data | Normalized to exactly your schema’s keys. A missing value is null and a missing list is empty. |
cost_cents | The LLM pass spends AI credits, capped at $0.05 a call and $0.50 a request. |
What one call replaces
A scraper for every site
You describe the fields, and selectors are optional.
A prompt chain
The LLM pass runs only for fields the free CSS pass left empty.
A shape check
The data comes back in your schema’s exact keys.

Questions about structured extraction
How do I extract structured data from a website with an API?
Send POST /v2/distill with urls (up to 50 a request) and a schema, either a JSON Schema object or a flat map of field names to descriptions. The response data comes back normalized to exactly your schema’s top-level keys.
Do I have to write CSS selectors?
No. css_schema is optional, and without it every field goes to the LLM pass. Supplying one fills the selector-addressable fields for free and escalates only the fields it left empty.
How is the LLM cost capped?
The caps are layered: $0.05 per LLM call, $0.50 per request, at most 50 escalations a request, and your monthly AI-credit balance. LLM extraction spends credits, not ops. Hitting a cap never fails the request: the affected fields come back null with a warning.
Why are some fields null in the response?
Missing values are normalized to null, and missing lists to empty, to keep the shape guarantee. The LLM pass is skipped, with a warning, when the page was flagged as blocked or a budget cap was reached.
Can I extract the same schema from a whole site?
Yes. Send discover_from with a seed url, a mode (sitemap, crawl or hybrid) and max_pages from 1 to 50 instead of urls.
Which plans include it?
Distill requires a paid plan, and on the free plan the request is rejected with a 402. Each completed URL is one op, and the LLM pass spends monthly AI credits: $5, $15 or $40 on Indie, Studio and Production.
