## 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 page-description-decision-agent-readiness-6ff06aee -d '<json body>'
```

Example prompt: Can you check whether https://example.com has a page description that passes the agent-readiness standard — give me the verdict, the evidence it found, and what I should do to fix it if it fails?

## When to prefer this

Choose this endpoint when you need a passive, read-only audit of whether a specific public URL's page description meets documented agent-readiness criteria, without triggering logins, purchases, or any side effects. Prefer it over generic SEO tools when you specifically need a structured pass/fail verdict with evidence sourcing suited for AI agent workflows, or when comparing against a prior baseline snapshot.

## Known failure modes

- Target URL is unreachable or returns a non-200 status — endpoint cannot fetch evidence
- Target requires authentication or blocks crawlers — passive fetch fails with access error
- Malformed or overly long URL input — validation error returned
- Page has no meta description tag — observation returns empty, verdict fails
- Rate limiting or upstream timeout from the target server causes incomplete evidence

## How this service works

Machine-readable description decision fetches current public evidence from the supplied target and evaluates the documented criterion. It returns the observation, threshold, verdict, exact evidence source, limitations and a mode-specific action. The check is passive: no login attempt, payload injection, exploit, purchase, form submission or load test is performed.

## Output

Returns a structured object containing: the observation (what was found on the page), the threshold (what is required to pass), a verdict (pass/fail), the exact evidence source (URL or HTML element), any limitations of the passive check, and a mode-specific action recommending what to do next.
