# x402 URL Extractor – SchemaForge

> x402 URL Extractor – SchemaForge is a paid API for AI agents from x402-url-extractor-production.up.railway.app, paid per call via x402, $0.25/call, status unknown (last checked 2026-10-02).

Generates JSON-LD structured data markup (Schema.org) for a business website, with a fix list and missing schema types identified, optimized for a given vertical like med-spas.

## 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-schemaforge-e101d9a2
```

Example prompt: Can you generate Schema.org JSON-LD structured data for my med-spa clinic at https://example-clinic.com in Austin, and tell me what schema types are missing and what I should fix?

## When to prefer this

Use this endpoint when you need to auto-generate complete, vertical-aware Schema.org JSON-LD markup for a business website — especially med-spas — and want both ready-to-use structured data and an actionable fix list. Prefer this over generic SEO audit tools when the output must be Schema.org compliant JSON-LD with specific missing-type diagnostics.

## Known failure modes

- Invalid or unreachable URL returns an error or empty graph
- Unsupported vertical returns no markup or generic fallback
- Missing required 'site' query parameter causes a 400-level error
- Private or bot-blocked sites may return incomplete or empty structured data
- Payment not received (x402) results in 402 Payment Required response
