Can it answer customer support questions on API's cryptic error messages? E.g. Give hints on changes needed in the request payload.

Assuming you can link the source code for the API's logic - that should work. Mileage may vary depending on exactly how vague the message are. For example if a single error message could mean 10 disjointed things, might not be able to exhaustively list them.
