FAQs

Is generated JSON Schema production-final?

It is a strong draft from samples. Review required fields, enums, formats, and edge cases before publishing contracts.

Does this support OpenAI structured outputs?

Draft schemas are a useful starting point; always validate against the provider’s supported subset and test with real payloads.

Why do results differ from browser extensions?

Server-side fetches can see a different HTML payload than a logged-in browser session. Cross-check when debugging personalization or geo variants.

Can I suggest an improvement?

Email a short description of the workflow and a redacted example. Useful, repeatable suggestions get prioritized.
