## 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-ready-site-ai-readiness-scorer-1eea32b7
```

Example prompt: Can you check how AI-agent-ready stripe.com is — score it out of 100 and tell me if it has an llms.txt, OpenAPI spec, MCP card, and x402 support?

## When to prefer this

Use this endpoint when you need a comprehensive, single-call audit of a website's AI agent discoverability posture — covering the full stack of discovery files (llms.txt, OpenAPI, MCP card, agent card, x402 manifest, sitemap) plus page-level signals. Prefer this over individual file-check siblings when you want an aggregate score and holistic picture rather than details on a single file type.

## Known failure modes

- Invalid or non-HTTPS URL provided — endpoint requires a valid https:// URL
- Target site is unreachable or returns non-200 status — checks may return nulls
- Site blocks the checker's crawler — files may be reported as absent even if present
- Slow-loading sites may time out before all checks complete
- Malformed llms.txt may cause validation errors but still return partial data

## How this service works

Is a site ready for AI agents? Scores llms.txt, OpenAPI, AI-crawler rules, sitemap, x402/agent/MCP files and readable HTML /100.

## Output

Returns a structured JSON object with an overall readiness score and per-file breakdown including: llms.txt validity, size, sections, links and issues; OpenAPI presence and validity; agent card and MCP card presence and validity; x402 manifest status; sitemap type and entry count; and page-level signals like HTTPS, HSTS, word count, noindex flag, HTTP status, and JSON-LD block count.
