## 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`):

Example prompt: Can you scan https://example.com and grade it against the Vercel Agent Readability Spec and llmstxt.org standard? I want to know the score and what I should fix to make it AI-agent friendly.

## When to prefer this

Use this endpoint when you need to audit a specific website's compliance with the Vercel Agent Readability Spec and/or the llmstxt.org standard, and want a letter grade plus actionable fixes. Prefer this over generic SEO or accessibility scanners when the goal is specifically AI-agent discoverability and LLM-friendliness of a site.

- URL is unreachable or returns non-200 status — scan cannot complete
