# x402 URL Extractor – /extract

> x402 URL Extractor – /extract is a paid API for AI agents from x402-url-extractor-production.up.railway.app, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-01).

Fetches a public URL and returns its title, description, JSON-LD structured data, and AI-readiness metadata for $0.05 USDC per call via x402.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 x402-url-extractor-extract-b018d1b3
```

Example prompt: Can you extract the title, description, and any structured JSON-LD data from https://example.com so I can see what metadata the page exposes?

## When to prefer this

Use this endpoint when you need quick, lightweight metadata extraction (title, description, JSON-LD) from a single public URL and want to assess its AI/structured-data readiness. Prefer this over /read (full page content) or /scan (deeper multi-signal scan) when you only need surface-level page metadata at the lowest cost ($0.05).

## Known failure modes

- URL is not publicly accessible or returns a non-2xx status — ok: false with error message
- URL parameter missing — request rejected with validation error
- Private or paywalled pages may return empty or partial metadata
- Payment not included or insufficient — HTTP 402 returned requiring x402 USDC payment
- Malformed URL input — error response from schema validation

## How this service works

Extract a public web page into clean structured JSON for agent workflows: title, description, main text, all JSON-LD, Open Graph and Twitter metadata, headings, links, and AI-crawler and structured-data signals. Follows redirects and enforces timeout, response-size, and SSRF safeguards.

## Output

Returns a JSON object with: ok (boolean), url (the fetched URL), title (page title string), description (meta description or null), jsonLd (array of JSON-LD objects found on the page), and aiReadiness object containing hasJsonLd (boolean) and schemaTypes (array of detected schema.org types).
