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-by-santos-b0cdc997

Example prompt: Can you audit https://acme.com for AI agent readiness and tell me what SEO, security, and accessibility issues it has, along with the scores?

## When to prefer this

Choose this endpoint when you need a multi-dimensional audit covering AI agent readiness (llms.txt, MCP, OpenAPI), SEO, security headers, and accessibility in a single call with structured JSON output and prioritized fixes — especially when evaluating whether a site is discoverable and usable by AI agents, which generic SEO or Lighthouse tools don't assess.

## Known failure modes

- Invalid or non-public URL returns an error or empty response
- Timeout if the target website is slow or unresponsive
- Private/intranet URLs not reachable from the audit server
- Rate limiting or payment failure with x402 protocol if USDC balance insufficient
- Incomplete results if the target site blocks headless crawlers
