I saw that there were many questions tagged with api (more than 100 at the moment).
I feel that for most of these questions, this is sort of a meta tag, and could be replaced by a tag for a specific API.
There are a few questions where this tags make sense, but most of those are 'shopping' question, asking
What API can I use to do X?
and these types of questions aren't exactly on-topic either.
Does the community feel that this tag is useful?
