# Dataset Entity Audit

> Dataset Entity Audit is a paid API for AI agents from agentreadiness.halowerk.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-14).

Passively fetches public evidence from a target URL or domain and evaluates it against a dataset entity criterion, returning an observation, verdict, evidence source, and recommended action.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 dataset-entity-audit-fc598ca6 -d '<json body>'
```

Example prompt: Can you run a passive dataset entity audit on https://data.example.com and tell me whether it passes the criterion, what evidence was found, and what I should do next?

## When to prefer this

Use this endpoint when you need a passive, read-only audit of a specific URL or domain for dataset entity signals without triggering any active probing, login attempts, or load. Prefer it over generic crawlers when you need a structured verdict with threshold, evidence source, limitations, and a concrete action recommendation in a single call.

## Known failure modes

- Target URL is unreachable or returns non-2xx status, resulting in inability to fetch evidence
- Target is behind authentication or a firewall, limiting observable public signals
- Malformed or overly short target URL rejected by schema validation
- No dataset entity signals found on target, leading to a fail verdict with limited evidence
- Comparison URL unavailable when change-detection mode is requested

## How this service works

Dataset entity 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 an observation describing what was found, the evaluation threshold, a pass/fail verdict, the exact public evidence source used, limitations of the passive check, and a mode-specific action recommendation. No login, payload injection, or active exploit is performed.
