## 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 agentkit-x402-site-audit-9312e43d
```

Example prompt: Can you run a full SEO and technical audit on https://mybrand.com/landing-page and tell me what issues it has, like missing meta descriptions, canonical problems, or bad security headers?

## When to prefer this

Choose this endpoint when you need a fast, structured, pay-per-call SEO and technical audit of a single webpage without setting up a full crawl tool. Ideal for spot-checks on landing pages, competitor pages, or client sites where you want score, indexability, metadata completeness, and security headers in one call. At $0.02 USDC per call via x402, it suits agent workflows that audit pages on-demand without subscriptions.

## Known failure modes

- Invalid or unreachable URL returns an error response
- Non-200 status pages may return partial data
- Payment of 0.02 USDC via x402 required; missing or invalid payment results in 402 response
- Rate limiting or Cloudflare Workers timeout for very slow target sites
- Dynamic JavaScript-rendered content may not be fully parsed

## How this service works
