Shameless plug - Use the new JobServe Web API to search for jobs your way

As my signature states - I work for JobServe in the UK.  Over the past few months I have been working on a new REST API (using the ASP.Net Web API from pre-beta to RTM) and it is now in official public beta.
Now of course, this isn't just so your good selves can start running your own job searches using whatever web-enabled client takes your fancy, but that is one of the cool benefits that has come out of it - and that's why we're calling it a public beta.
At the time of writing, you can use the API to run almost any job search that you can on the website.  As you would expect, you can get the results in XML or JSON (also GET requests with search parameters in the query-string are supported as well).  Note that JSONP is not currently supported - but it's slated for a future release.

Sounds great, how do I get in?

In order to get cracking with this - you need to request an API token.  This is not an automated process but we should be able to get you set up in a day or two at most.  When filling out this form it's important to be honest about what you intend to do with the API.  That way, we'll know what kind of request patterns to look for and are less likely to revoke access at a later date.

…And then what?

Once you've got your API token - just follow the documentation that I've put together on the JobServe Web API mini-site to get started.  You can contact the support team by email from the site if you have a problem - but please don't contact us looking for code on how to make HTTP requests; that's outside our remit!
If you're environment is .Net, and you don't mind sending/receiving XML, we are making available DataContractSerializer-compatible classes that are generated live from the latest API Types schema.  These are available from the Source Code download page.  These code files (C# and VB.Net available) give you compatible types for all the types used by the API.  Note that these classes aren't, however, natively suitable for JSON - some might work with Json.Net, for example, but they're not intended to.
The most likely usage of this API is to extract the Permalink for a desirable job.  This will take you straight to that job on the JobServe website, from which point you can then apply in the browser as normal.  The sharp-eyed among you will notice in the API types list that clearly we have got objects that can manage the application process outside the browser - but at the moment I'm sorry to say that we have no plans to make that bit public - this is chiefly for the security of our users instead of bloody-mindedness.
So, get yourself signed up for an API token and start writing!  Will you setup an azure service to notify you of jobs?  Perhaps you'll write yourself a personalised search app?  If you want to share any code with us to help others (we might put it on the aforementioned source code page), then please do.

Can I use SSL?

If you're concerned about security - SSL endpoints are available for all operations - just use https://services.jobserve.com instead of http://services.jobserve.com.

Any code samples on the way?

I will try and put together a code example for accessing the service in C# 5 with the 'modern' HttpClient using async/await.  If you do have problems making HTTP requests - then I can also heartily recommend StackOverflow (I am known to hang around there a bit, so I might even see your question) as a great source of help.  Provided, that is, you try your best solve your problem first!

Happy coding!  Oh, and happy job hunting!
