DataUsabilityVerdict
"Can this external data be safely used?"
Deterministic verdict for external API data. USABLE or UNUSABLE. Zero LLM, stateless.
Introduction
DataUsabilityVerdict is a defensive API that answers one simple question: "Can this external data be safely used?". It returns a deterministic verdict — same input, same output. Always. Zero LLM, stateless, designed to integrate into your automated pipelines.
Input
Send a POST request with a JSON payload. See the example on the right.
Output
The response contains a verdict and explanatory signals. See the example on the right.
Verdicts
| Verdict | Meaning |
|---|---|
| USABLE | Data can be safely used. |
