## 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 barriere-access-keys-audit-af0c171f -d '<json body>'
```

Example prompt: Can you passively audit https://example.com for conflicting access keys and give me a verdict with the evidence source and any recommended action?

## When to prefer this

Choose this endpoint when you need a passive, non-invasive audit of a public URL or domain specifically for conflicting access keys — without triggering any login attempts, payload injections, or load tests. Ideal for pre-launch checks, vendor vetting, or continuous monitoring scenarios where you want documented evidence, a threshold-based verdict, and an actionable recommendation without touching authenticated or private surfaces.

## Known failure modes

- Target URL is unreachable or returns a non-2xx response, resulting in inability to fetch evidence
- Malformed or non-public URL provided, causing normalization or validation failure
- Target domain has no detectable access key artifacts, returning an inconclusive observation
- Rate limiting or blocking by the target server preventing evidence collection
- Baseline object is malformed or incompatible, causing comparison to be skipped

## How this service works

No conflicting access keys 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), the threshold used for evaluation, the verdict (pass/fail/warning), the exact evidence source, any limitations of the passive check, and a mode-specific recommended action. No login, payload injection, or exploit is performed.
