As you might surmise from its name, APIFinder is a resource to help developers find and learn about using APIs (application programming interfaces). The site is a growing index of various APIs—both open source and proprietary, free and for sale. The APIs listed on the site come from just about anywhere and everywhere. Each API entry tells you a little about what the API does so you can decide whether it will serve your needs. The entries include a link to the API's provider (creator) so that you can find the API to try it out. We think it beats the heck out of hunting and pecking across the Internet using keywords!

As great as it is to have a one-stop-shop for finding hundreds of APIs, we know that sometimes it's great to get help and ideas from other developers about implementing APIs in useful and unique ways. Therefore, APIFinder also features articles (more information in the "Articles" section below).

The API Index
You can browse our API index by its "function" (i.e. what it does, for example "search") or by the languages that it supports. Because of the popularity these days of Web 2.0-style APIs—free Web service-based APIs that allows you to pull a service into your application over the Web using XML—you'll find the largest number of APIs today listed under Web services. But we can include a listing for any kind of API, including Visual Basic, Java, Windows, Apple, and more. You can browse the API index for these types of APIs using the "language" categories, which on this site is used loosely to describe the platform or environment an API is suited for.

We don't have every API ever made listed in our index—not by a long shot. There are lots of APIs out there that you might know about that we haven't seen yet. So please help us by using the "Submit an API" form to tell us about an API that we can add. The form is quick to fill out; just register with a log in name and email address and you can start submitting APIs right away.

Articles
While the API index itself is a great resource, we also want to provide support to help you succeed in using APIs. For that reason the site also includes articles. An article can be documentation, reviews, mashups, examples, or even an interview or opinion. Anything that will help another developer get ideas about how to implement an API or will give them more context about a given API. An article doesn't need to be long. A few paragraphs and maybe a screen shot or some code may be just enough to help someone else get their own code flowing.

Each article is semantically related to the API(s)s that it is about. So you can see whether we have any articles about a given API just by going to the API's page on the site.

Your ideas, implementations, opinions, and mashups are exactly the kind of content that we want for articles. And it's simple to add them. Use the "Add an Article" link to contribute an article to the site. We have an easy-to-use, robust Web form that will let you input text, images, and code. Just tell us which APIs your article relates to and submit it to an editor. We'll review your submission, and after a short evaluation period, your article will be shared with the rest of the APIFinder community! Before you submit an article, please just make sure that the API(s) about which you are writing is already included on the site. If it isn't there, please submit it before submitting your article.

Your Usability on APIFinder
Every submission, whether an API or an article, will be reviewed promptly by an editor. Once the content has been reviewed for accuracy (and to keep out spam), we will make your submission live. Everything that you submit will be attributed to you by your user name so that others who use this site know who to thank for the assistance. Your submissions are always editable by you using your "My Profile" page. You can even list a bio for yourself so that others can learn more about you and what you do.

Finally, this site is supported by two forums, which you can use to talk about API programming with other users of the site. (At this time, please be aware that the forums require a separate registration/login.)
