An API is a set of methods to use a particular program. For example, if redbox wants you to be able to search for videos, they would build an API method for that (instead of leaving you to figure out how to do it for yourself).
Anything else, you'd need to be more specific. "What can I do with an API?" is a bit like asking "What can I do with a piece of paper?"
Twitter for example has an API (i.e a feed of data) - when you embed Twitter on your site you're basically using their API/grabbing the data, similarly to other services.
How you integrate and use the data/output is up to you most of the time, with Twitter for example you pull the tweets in and can then place them and style them however you want.
What are Api's for and what could I do with one? For example if I used redbox API what could I do with it?
You can retrieve data from them.
For Redbox you can get their data such as all the movies they have and list them or whatever you choose to do with it.
I hope I got that right.

ha, I wouldn't say that too loudly when twitter is listening.
Twitter can kiss my ass! :P
