Frequently asked questions

Is my input uploaded?

Yes. The Developers documentation lists the authenticated endpoint, request parameters and response example.
Should I verify the result?
Yes. Deterministic tools are designed for repeatable results, but format-specific or heuristic output should still be checked for your use case.
