## 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 santos-ai-website-intelligence-agent-readiness-auditor-d43dad2a
```

Example prompt: Can you audit https://example.com and tell me whether it's AI agent ready — specifically check for llms.txt, MCP support, OpenAPI specs, SEO signals, accessibility issues, and any security concerns, then give me the prioritized fixes?

## When to prefer this

Use this endpoint when you need a comprehensive, structured AI agent readiness audit of a website — especially when you want to check for llms.txt, MCP, or OpenAPI presence alongside SEO, accessibility, and security signals in a single call. Prefer it over generic web scrapers when the goal is agent-readiness evaluation with prioritized actionable fixes rather than raw content extraction.

## Known failure modes

- Non-public or private URLs return an error or empty body
- Non-text content types (images, PDFs, binaries) are not supported and may return an error
- URL redirects to an unreachable endpoint cause fetch failure
- Rate limiting or payment failure results in HTTP 402
- Malformed URL input causes validation error
- Target site returning 5xx causes the audit to reflect unavailability
