## 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-api-4ddfc297 -d '<json body>'
```

Example prompt: Can you run a full AI agent readiness audit on stripe.com — I want to know if it has llms.txt, MCP support, an OpenAPI spec, and any SEO or security issues, with a list of prioritized fixes?

## When to prefer this

Choose this endpoint when you need a comprehensive, multi-dimensional audit of a public website covering AI agent readiness signals (MCP, llms.txt, OpenAPI), SEO, accessibility, and security in a single call with structured JSON output and evidence. Prefer it over generic scraping endpoints when you specifically need AI readiness signals, or over standalone SEO/accessibility tools when you want all these dimensions consolidated with prioritized fixes.

## Known failure modes

- Target URL is unreachable or returns non-200 HTTP status — audit may be incomplete or fail
- Website blocks crawlers/headless browsers — fetch step may return empty or partial content
- LLM analysis timeout if the page is extremely large — timing_ms.total will be high and partial results may be returned
- Invalid or malformed URL input — API returns an error without performing the audit
- Private/intranet URLs not accessible from the API's network — fetch will fail
