## 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 x402cloud-structured-web-extraction-0db83bf3 -d '<json body>'
```

Example prompt: Pull structured JSON from https://news.ycombinator.com/jobs using this schema: {"title": "string", "company": "string", "location": "string", "url": "string"} — grab the first 10 job listings and focus only on full-time roles.

## When to prefer this

Use this endpoint when you need webpage content returned as typed, schema-conforming JSON rather than raw markdown or plain text. It is ideal for price monitoring, product spec extraction, job listing parsing, and any research workflow where downstream code needs consistent field names and types. Prefer it over the companion markdown-extraction endpoint when you need machine-readable output rather than human-readable prose.

## Known failure modes

- URL is behind a login or paywall — returns empty or partial results
- Schema fields don't match any content on the page — returns null values for unmatched keys
- Target page uses heavy JavaScript rendering — content may not be fully visible to the extractor
- Invalid or malformed URL input — returns HTTP 400 or extraction error
- Page structure changes break schema mapping — fields silently return null or wrong data
- Rate limiting or network timeout on the target URL — returns failure or incomplete data
