I'm writing a first draft of an API for Jobpic.com. Mostly just for fun, I have a friend who is going to write an app for us.

I love developer friendly APIs.

I want to model ours after a great one. What are some of your favorites?

I like 37signals Basecamp API (not as much Highrise and Campfire), but a standout for me is Wufoo's:

http://wufoo.com/docs/api/

Really nicely documented.

Amazon's product advertising API is nice. You can't help but get startup ideas browsing through the documentation.

It's not a web service, but I always thought Qt had one of the best APIs out there in terms of style, consistency, and documentation. It's worth looking at just from a packaging perspective.

Just keep it simple..that's the most important thing. Simple POST name/value pairs and JSON output. I don't care if it's technically REST or not. One big long document describing every call and response (makes it easy to search with CTRL-F). Lots of examples. Complete example code. High level libraries that implement the boring parts. A direct email address to the developer.

The Last.fm API (http://www.last.fm/api/intro) is the best one I've come across.

It has the most comprehensive and intuitive documentation of all the APIs I've used. Their format for API documentation should become a standard.

Not SOAP :) It's a pain to consume compared to POX (plain old XML) or JSON.

While this doesn't directly answer your question, I've found this to be helpful in the past: The Little Manual of API Design - http://chaos.troll.no/~shausman/api-design/api-design.pdf

awesome. I've been looking for something that talks about api design...

I also like this josh bloch google tech talk video "How to design a good API and why it matters.": http://www.youtube.com/watch?v=aAb7hSCtvGw

Twilio's REST API (http://www.twilio.com/docs/api_reference/REST/) is really easy to understand, very sensible. It's practically self-documenting, but it's backed up with thorough documentation and examples. One can get up and running very quickly because of that. They have clearly spent a lot of time getting the API right.

Paypal has one of the worst APIs I've ever used. It's a useful model of what to avoid, particularly its multiple formats and its flakey and often outdated sandbox testing servers.

Take a look at Friendfeed's API V2 (http://friendfeed.com/api/documentation). Not only does it use very intuitive RESTful architecture, but it also has very awesome documentation and libraries.

Of course, now that they're with Facebook the developer support will likely not be as good, but the API is great as it is regardless.

I suggest taking your time when you implement the first version of your API. Nothing is worst than developing based on a rushed v1 API, which later gets modified without you knowing. No one wants to be caught calling a deprecated function that then gets removed.

Furthermore, try to keep all of your API libraries up-to-date. For example, I was almost driven crazy by Google's v1.0 Python Spreadsheet library's lack of support for insertion based on case-sensitive row names (See http://code.google.com/apis/spreadsheets/data/1.0/developers...). There is no documentation regarding the requirement that the row name must contain only lower case characters. The .NET library is v3.0 and appears to offer much greater support for this type of basic functionality.

Amazon has the most useful APIs out there. Don't copy them though.

So many small companies put out giant behemoth APIs with crazy security hoops because that's what Amazon does and Amazon's stuff is really cool. As a result, nobody outside the dev team can figure out how to authenticate, so nobody actually uses the API.

Check out Twiddla's API (http://www.twiddla.com/API/) for an example of how to keep things lightweight. 2 POST endpoints and an IFRAME syntax. Only the bare minimum security, and a huge emphasis on getting your thing up and running without having to sweat the API.

My favorite is Flickr API

http://www.flickr.com/services/api/

Provides a lot of functionality. Basically anything you can do on the website you can do through the API. The names of the calls are intuitive. Provides different formats.

And most importantly has libraries available for different languages that will make the calls for you.

I think Twitter's is great, and digg's isn't half bad either.

On the other side of the coin, Google's GData APIs (e.g., Calendar, YouTube), Paypal and Facebook are cumbersome IMHO.

ivankirigin• 17 years ago

A good test is how easy it is to get started. If you can just make a call to curl to get started, awesome.

If things change without warning, that is bad.

If the site is down often, that is bad.

While users are awesome, and it is great to have a developer community, depending too much on them to do your QA is asking a lot.

Take a look at Webmachine http://bitbucket.org/justin/webmachine/.

If you're writing a RESTful API try using webmachine. At the very least, you'll feel like you're writing the best API ever.

*NOTE: I have no relation to webmachine, just really impressed with the elegance how it is written and the API's it help produce.

I really admire the Sun Kenai (Cloud) API:

http://kenai.com/projects/suncloudapis/pages/HelloCloud

It's a delightfully clean RESTful JSON API.

Twitter -- it's a popular service, and there are libraries for most of the languages I've tried to write Twitter-related applications in.

Tumblr -- it's simple, it's clean, it returns a Tumblelog as XML over an HTTP request. You can also write posts over HTTP as well.

I recently integrated with Zendesk and it was painless. Simple and straightforward.

a sub-question: could someone comment on other types of apis like windows (win32) or posix api?

_pius• 17 years ago

Definitely read what Joshua Bloch has to say about API design. I'd highly recommend this talk he gave: http://www.infoq.com/presentations/effective-api-design

Typically he talks about APIs more in the sense of library design than web service design, but he's very relevant nontheless.

Any of Amazon's APIs - Product Advertising, AWS, et al.
