Example prompt: Can you audit example.com to check whether its content license is clearly documented and tell me what you found — the verdict, where you found the evidence, and what action I should take?

## When to prefer this

Choose this endpoint when you need a passive, read-only audit of whether a specific public URL or domain clearly documents its content license, especially in AI agent readiness, publisher compliance, or data ingestion pipelines where usage rights must be verified before content is consumed.

## Known failure modes

- Target URL is unreachable or returns a non-200 status, resulting in an inconclusive verdict
- Target uses JavaScript-only rendering that prevents passive content inspection
- No public license information is present, yielding a clear fail verdict
- Malformed or excessively long URL rejected with input validation error
- Rate limiting or access restrictions on the target may prevent evidence retrieval

## How this service works

Content license 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 result containing the observation (what was found), the threshold applied, the verdict (pass/fail), the exact evidence source URL or element, any limitations of the passive check, and a mode-specific recommended action — all without performing any login, form submission, purchase, or exploit.
