When it comes to the Translate API, you're better off posting in the Translate API forum. I would post a link, but it seems you've found it already. If I'm mistaken in that, just let us know, and we'll dig up the link.

Trying to do Hello World with google translate. Have enabled the translate api on the project and created a billing account.
But I get nothing but errors when using the sample code provided. Project console shows the errors so the key appears to be valid. It also shows I have a quota so the billing appears to be valid.
What steps can I take to debug this? Judging by the sheer volume of posts on this subject it would appear that this is a very frequent problem for new users.
