Stripe and Mailgun and Twitter are some of the best documented, clearest to use APIs.

The Google Maps API i can usually get cool stuff happening with quickly.

My favorites overall are probably Sunlight labs APIs though: http://services.sunlightlabs.com/

The sunlight labs stuff looks cool.

I still think the Amazon S3 API is really nice.
Google analytics API. We use it, have been for a few months and its excellent.
Zencoder's api is solid and easy to work with.
I don't think we've even scratched the surface of the things we can do with Twitter's API. After playing with tons of them, Twitter's potential to inform so many projects, publicly or privately, is huge. I love it.
