Exversion is hoping the need to access wide-ranging open datasets has matured enough to create a viable business as an open data marketplace. Their new Exversion API provides developers with a RESTful interface to search and access the open datasets stored on the Exversion data platform. At present, the API returns queries in JSON or XML format, with full XML support to be provided in the near future.
In addition to the the new APIs we highlighted earlier this week, there are plenty of other new entries in our API directory. Some other notable new APIs include a location based advertising API from Placecast, an open platform for data sharing from Socrata, and a new service from Sony Ericsson for music identification and music chart access.
