Alchemy API's transaction usage is returned under a response body property called usage. Alchemy API is being put to bed in favour of Watson NLU and its friends. While porting code from using Alchemy to Watson I noticed I do not see usage being returned in responses from Watson. Am I missing something or does anyone know how to count Watson transaction usage?
I've searched pretty hard in their docs and online but there doesn't seem to be any mention of this. I've also watched responses received by their Node SDK here and could see no trace of usage in the response body or headers. Any pointers much appreciated.
