## 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 agent-market-lab-web-data-page-to-structured-data-91bcfd98 -d '<json body>'
```

Example prompt: Can you pull the structured data from https://www.acmecorp.com/about — I need the page title, description, any JSON-LD, and main headings so I can research what the business does.

## When to prefer this

Choose this endpoint when you need quick, pay-per-call structured extraction of a single public web page — especially for metadata, JSON-LD, Open Graph, and headings — without setting up a full scraping pipeline. It is well-suited for ecommerce product research, business intelligence on websites, and lightweight page analysis. Prefer it over heavier crawlers when you only need one page at a time and want structured output rather than raw HTML.

## Known failure modes

- Private hosts or IP literal URLs are rejected with an error
- Pages requiring JavaScript rendering may return incomplete data (flagged via renderingLikelyRequired: true)
- URLs exceeding 2048 characters are rejected
- Unreachable or non-200 pages may return error status in the ok field
- Payment failure over x402/Base will block the call

## How this service works

Pay-per-call public-web extraction, ecommerce data including a 10-product batch, change detection and website business research for autonomous agents via x402 on Base.

## Output

A JSON object containing: ok status, the fetched URL, HTTP status code, page metadata (title, language, description, canonical URL, Open Graph), headings array, JSON-LD array, a plain-text excerpt, a confidence rating (e.g. 'high'), provenance info (bytes read, source URL), fetch timestamp, and a flag indicating whether JavaScript rendering is likely required.
