Open311 allows developers to create third-party apps to report and view citizen neighborhood issues such as potholes to graffiti and more using a city's 311 reporting system. Now on version 1, the RESTful Inquiry API is the tool used to query the 311 database. HTTP GET calls can be sent to the API to list services and expand details on specific services. Information for specific cities accessible with Open311 can be found in the wiki. The API is heavily supported in New York City. The Inquiry API supports XML and JSON formats.
