It’s demo time for the two dozen startups from incubator Y Combinator. Though there are many that have yet to launch publicly, the focus of the program is to get quickly from idea to product. It’s notable how many have used APIs, either to boost their features or as a forward-thinking move to invite developer collaboration.
Notifo provides “mobile notifications for everything.” Right now, that means push messages via its iPhone app. Rather than alerts that are specific to an app, it creates a platform upon which developers can build. Push.ly is an example implementation, which connects Notifo to Twitter search, sending a notification whenever someone references you in a tweet.
Crocodoc is a service to help people collaborate on documents. The editor can be embedded into a web page. Then, with the Crocodoc API, you can upload, embed and delete documents programmatically.

That means your site can accept uploads and then let Zencoder worry about formats. We wrote about services that take care of the harder stuff in Infrastructure APIs: New Site in a Box.
In addition to those above with APIs, a healthy percentage of Y Combinator companies are using APIs. Some examples:
