# Content License Decision Checker

> Content License Decision Checker 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 and evaluates whether its content licensing meets a documented criterion, returning an observation, verdict, evidence source, and recommended action.

## 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 content-license-decision-checker-916d1638 -d '<json body>'
```

Example prompt: Check whether the content on https://example-publisher.com is licensed in a way that allows AI agents to use it — I need a verdict, the evidence source, and any limitations.

## When to prefer this

Choose this endpoint when you need a passive, read-only verdict on whether a specific URL's content license meets a defined criterion — particularly for AI agent readiness, content reuse eligibility, or publisher compliance workflows. It is distinct from general content scrapers because it specifically targets license signals and returns a structured verdict with evidence citations. Prefer it over manual review when you need scalable, repeatable license checks without authentication or active probing.

## Known failure modes

- Target URL is unreachable or returns non-2xx — evaluation cannot proceed
- No license information is publicly detectable on the target — verdict may be 'indeterminate'
- License text is ambiguous or non-standard — limitations field will flag low confidence
- Target uses JavaScript-only rendering that blocks passive fetching — evidence may be incomplete
- Malformed or excessively long URL input triggers validation error

## How this service works

Content license 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 response containing: the observed licensing evidence found on the target, the evaluated threshold/criterion, a pass/fail/uncertain verdict, the exact URL or element where evidence was sourced, known limitations of the passive check, and a mode-specific recommended action — all without performing any login, form submission, or exploit.
