## 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 proof402-page-profiler-bc77e7a7
```

Example prompt: Can you profile the page at https://example.com and tell me its title, meta description, canonical URL, Open Graph tags, and how many internal vs external links it has?

## When to prefer this

Choose this endpoint when you need structured page-level metadata from a single public URL — especially title, description, Open Graph, canonical, JSON-LD types, and link counts — without running a full browser or crawler. It is well-suited for SEO audits, content enrichment pipelines, link verification, and pre-fetch intelligence for agents that need to understand a page before visiting it. Prefer it over generic scraping tools when you want normalized, schema-consistent output settled via x402 micropayments on Base.

## Known failure modes

- Non-public or firewall-protected URLs return an error or timeout
- Malformed or non-URI input values are rejected by schema validation
- Pages requiring JavaScript rendering may return incomplete metadata
- Very slow origins may cause request timeouts
- Non-HTML responses (e.g. PDFs, images) may yield empty or partial metadata fields

## How this service works
