## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability api-strale-io-b329e0d0 -d '<json body>'
```

Example prompt: Scrape https://example.com/product/123 and extract structured data using this schema: {"name": "string", "price": "number", "description": "string", "inStock": "boolean"} — the page is JavaScript-rendered so you'll need a real browser to see the content.

## When to prefer this

Choose this endpoint when you need to extract arbitrary structured data from any web page using a schema you define at call time, especially when the page is JavaScript-rendered and requires a real browser. Ideal when you need flexible, schema-driven extraction rather than a fixed scraper for a known site type (like pricing pages or SEO audits, which have their own dedicated endpoints on this provider).

## Known failure modes

- URL is unreachable or returns a non-200 status — extraction fails with an error
- Schema fields cannot be mapped from page content — returns nulls or empty values for unmatched fields
- JavaScript-heavy SPA takes too long to render — timeout error
- Malformed or invalid JSON schema provided — validation error before scraping
- Page requires authentication or blocks headless browsers — partial or empty extraction
- Schema too complex or deeply nested — AI mapping may be incomplete

## How this service works

Extract structured data from any URL using a caller-defined JSON schema. Browserless renders the page, AI maps content to your schema.

## Output

A JSON object conforming to the caller-provided schema, with fields populated by AI-mapped content extracted from the fully browser-rendered page. Fields that could not be found may be null or omitted.
