## 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 agentshelf-page-audit-2e614edf -d '<json body>'
```

Example prompt: Can you run a full SEO and technical audit on https://www.example.com and tell me the score, any issues found, and whether it has proper meta tags, canonical tags, and structured data?

## When to prefer this

Use this endpoint when you need a structured, machine-readable SEO and technical audit of a single public URL — including score, meta tags, robots, canonical, JSON-LD, and H1 data — rather than a full site crawl or content analysis. It is SSRF-safe and costs exactly $0.01 USDC per call; try the free sandbox endpoint POST /v1/sandbox/page-audit first if available.

## Known failure modes

- URL is not publicly reachable or returns a non-200 status, resulting in a failed or partial audit
- SSRF-safe filtering blocks private/internal IP ranges or localhost URLs
- Malformed or missing URL input returns a validation error
- Page takes too long to respond, causing a timeout
- URL exceeds the 2048-character maximum length limit
