## 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-verifiable-citations-decision-9f483bb9 -d '<json body>'
```

Example prompt: Can you check whether https://example-news-site.com/article/climate-report has agent-verifiable citation links — I need to know the verdict, what evidence was found, and any limitations of the check?

## When to prefer this

Choose this endpoint when you need a passive, read-only, structured verdict on whether a specific URL's citations are verifiable by AI agents — particularly useful for content ingestion pipelines, publisher audits, or agent-readiness compliance checks. Prefer it over generic scraping tools because it returns a structured decision with verdict, threshold, and evidence rather than raw HTML. Use it when you need auditability of a page's sourcing without any active interaction like login or form submission.

## Known failure modes

- Target URL is unreachable or returns a non-200 status — check may fail or return incomplete evidence
- Target page uses JavaScript rendering that prevents passive evidence collection — observation may be limited
- Citation links are present but behind authentication walls — passive check cannot follow them
- Malformed or non-HTTP URL provided — normalization may fail
- Rate limiting or bot-blocking on the target site may prevent evidence retrieval

## How this service works

Agent-verifiable citations 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 decision object containing: the observed citation linking behavior on the target page, the threshold or criterion being evaluated, a pass/fail/unclear verdict, the exact evidence source URL used, limitations of the passive check, and a mode-specific action recommendation. No login, form submission, or exploit is performed during the check.
