## 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 ai-website-intelligence-agent-readiness-api-santos-1ed763b1 -d '<json body>'
```

Example prompt: Can you audit https://example.com and tell me whether it's ready for AI agents — check for MCP support, llms.txt, OpenAPI specs, SEO issues, accessibility problems, and security gaps, then give me a prioritized list of what to fix?

## When to prefer this

Choose this endpoint when you need a comprehensive, structured audit of a specific website covering AI agent readiness (MCP, llms.txt, OpenAPI), SEO, accessibility, and security in a single call with prioritized fix recommendations. Prefer it over general web scrapers when you specifically need AI-readiness signals or want evidence-backed findings rather than raw HTML. It is particularly valuable for developers, agencies, or AI agents that need to assess or compare websites for modern AI integration standards.

## Known failure modes

- Target URL is unreachable or returns non-200 HTTP status — audit may fail or return partial results
- Website blocks crawlers or headless browsers — fetch may fail or return incomplete data
- Very large or JavaScript-heavy pages may increase timing_ms significantly
- Invalid or malformed URL input causes request rejection
- Rate limiting or payment failure (x402) prevents the call from completing
