Expo, Live.com’s socially-networked classifieds site has launched an API. This adds them to the growing list of MS sites that have web services available for public consumption. You can see the current list on MSDN (and sometime soon on Live’s own dev center).
The API is available in both a REST and SOAP interface. The REST interface returns modified RSS. All of the listings are geo-tagged for easy map integration and all of the user calls rely on Expo’s public facing user nickname (not the lister’s Passport).
The API includes the following calls:
ListingsByCategoryKeywordLocation
This function returns Expo listings filtered by keyword, category and location.
ListingsByUser
This function returns listings posted by a particular user, identified by their nickname.
GetCategories
This function returns all of the available categories and attributes on the site.
You can learn more anout the Expo API on MSDN.
This marks the first API by MSN.com/Live.com to be released with a RESTful interface. MSN Search (my former team) has RSS feeds, but their formal developer API is SOAP. It’s good to see Live.com move towards the preferred interface of the web hacker.
