## 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 citation-links-audit-agent-readiness-ab174fa4 -d '<json body>'
```

Example prompt: Can you run a citation links audit on https://acmecorp.com and tell me whether the site passes the citation evidence threshold, what evidence was found, and what action I should take?

## When to prefer this

Choose this endpoint when you need a passive, read-only audit of citation links on a public URL or domain specifically for agent readiness evaluation. It is distinct from general link checkers because it evaluates against a documented criterion and returns a structured verdict with evidence sourcing and action guidance — making it suitable for automated agent pipelines that need deterministic pass/fail signals about citation health.

## Known failure modes

- Target URL is unreachable or returns non-200 status — audit cannot proceed
- Target domain resolves to a private or localhost address — rejected for security
- Malformed or too-short URL input — validation error returned
- No citation link evidence found on the target — observation returns empty, verdict likely fails
- Rate limit or payment failure (x402) — call rejected before audit runs

## How this service works

Agent-verifiable citations audit 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 report containing: the observation (what was found on the target), the evaluated threshold, a pass/fail verdict, the exact evidence source URL, any limitations of the passive check, and a mode-specific recommended action. No authentication, payload injection, or form submission is performed during the check.
