## 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 saylor-innovations-agent-readiness-checker-16b9a43c
```

Example prompt: Can you check how AI-ready saylorinnovations.com is — I want to know if it has llms.txt, an agent card, MCP or x402 discovery files, and whether it's blocking any AI crawlers?

## When to prefer this

Use this endpoint when you need a quick, structured audit of whether a specific website is discoverable and usable by AI agents — covering the full stack of signals: llms.txt, robots.txt AI rules, sitemap, agent card, OpenAPI, MCP, and x402. Prefer this over manual inspection or general crawl tools when you need a scored, actionable report with specific recommendations.

## Known failure modes

- Invalid or unreachable URL returns error or low score with failed checks
- Domain without any agent-readiness files returns score near 0 with all checks failing
- Malformed query param (missing url) results in validation error
- Timeout or network issues reaching the target site may cause incomplete check results

## How this service works

Check how ready a site is for AI agents - llms.txt, robots.txt AI crawler rules, sitemap, agent card, OpenAPI, MCP and x402 discovery files with a score

## Output

A JSON object with a 0–100 readiness score, the checked origin, number of checks passed, individual check results (name, pass/fail, detail), a list of AI crawler policies per bot (blocked or not, explicit rule), a list of blocked AI crawlers, and concrete recommendations for files or rules to add to improve agent discoverability.
