## 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 agent-tools-site-audit-7b486a66
```

Example prompt: Can you audit https://example.com and tell me its AI-agent readiness grade and what I'd need to fix to improve its score?

## When to prefer this

Use this endpoint when you need to programmatically verify whether a website is properly configured for AI agent consumption — especially before citing, paying, or repeatedly querying a site. It is purpose-built for agent-to-agent trust verification and surfacing llms.txt and related AI readiness signals, which generic site auditors or SEO tools do not cover.

## Known failure modes

- Invalid or non-absolute URL returns a validation error
- Unreachable or offline target URL may return a network error or low score
- Non-HTTP(S) URLs are rejected by schema validation
- Payment not provided or insufficient results in 402 response
- Rate limiting may apply if too many audits are performed in succession

## How this service works

Primary-source tools for AI agents: verify before you pay, cite, or repeat.

## Output

Returns a JSON object with a letter grade (e.g. 'B'), an integer score (e.g. 80), and an array of fix recommendations (e.g. ['Add /llms.txt ...']) describing what the site needs to improve its AI agent readiness.
