Since that time LinkedIn has gone public (LNKD anyone?). And perhaps more importantly for developers, they’ve also released an update to their APIs including the addition of new Jobs and Companies APIs. LinkedIn notes that you can use the new Companies API to:
Display a detailed overview of company information in combination with LinkedIn data. Search across company profiles by industry, location, size, and more. Enable your users to follow a company and see suggested companies to follow.
and the Jobs API like so:
Search LinkedIn’s jobs by company, industry and more to display relevant jobs to your users. Post and retrieve LinkedIn jobs for a company, and enable people to save jobs to their LinkedIn accounts and retrieve job suggestions.
LinkedIn provides a number of example calls on the API overview page. As of this writing, it doesn’t appear that the LinkedIn Apigee console has been updated for these new APIs yet, so for now you’ll need to try them out outside of that tool.
