## 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 httpay-website-audit-api-a823c70f -d '<json body>'
```

Example prompt: Can you run a full health audit on https://example.com — I want to know if the SSL cert is valid, how fast it responds, what the HTTP status is, and whether it has meta tags, OG tags, a robots.txt, and a sitemap.xml?

## When to prefer this

Choose this endpoint when you need a quick, all-in-one website health snapshot covering SSL, response time, status code, and SEO metadata in a single call without managing API keys or subscriptions. Ideal for agents performing automated site monitoring, SEO audits, or pre-launch checklists where micropayment billing is acceptable.

## Known failure modes

- Invalid or unreachable URL returns an error response
- Target site blocks automated requests (403/429 from target)
- SSL handshake failure if target has severely broken TLS
- Timeout if target site is very slow or unresponsive
- Payment failure if USDC balance insufficient or x402 transaction rejected
