## 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 webextract-web-page-to-markdown-structured-json-api-bad9e6f5
```

Example prompt: Can you grab the page at https://www.example.com/product/blue-widget and pull out its price, availability, product name, and any tables — plus a clean Markdown version of the content?

## When to prefer this

Choose this endpoint when you need both a human-readable Markdown rendering and structured JSON extraction (product, metadata, tables) from a single web page in one call. It is ideal for e-commerce price/availability checks, article ingestion pipelines, and table extraction tasks where consistent output schema is required. Prefer it over generic scraping tools when you need fixed-schema JSON with built-in structural validation (row/column checks) and robots.txt compliance out of the box.

## Known failure modes

- URL is blocked by robots.txt — returns an error indicating the page cannot be fetched
- URL is not publicly accessible (requires login or paywall) — may return empty or partial content
- Malformed or non-HTTP/HTTPS URL — validation error on the url parameter
- Page returns non-200 status (404, 500, etc.) — upstream HTTP error surfaced
- Product or metadata fields are null when page does not contain structured data (e.g. no JSON-LD)
- Tables array is empty if page contains no tabular content
- Markdown may be truncated for very large pages (indicated by markdown_truncated: true)

## How this service works

Fetch a public web page (robots.txt respected) and return cleaned Markdown plus fixed-schema JSON: article metadata, product/price, and tables with row/column checks.

## Output

A JSON object containing: the final resolved URL, fetch timestamp, schema version, full Markdown rendering of the page content, article metadata (title, description, authors, language, published/modified dates, site name, content type), product/price object (name, brand, SKU, GTIN, price, currency, price range, availability, rating, description, image), and an array of tables (headers, rows, caption, row/column count, consistency checks), plus word count and a truncation flag.
