The service provides continuously updated information about locations and pricing of available parking in selected areas of San Francisco. DataSF, the city government's open data initiative, collects and distributes the information to help drivers choose when to drive and when to choose other transportation options. Data is provided by off-street parking providers and by sensors that report status of individual street parking spaces as occupied or vacant.
API methods support submission of search parameters, including location (latitude/longitude and preferred radius), type of parking desired (street or off-street), and whether or not to include rate information. Returned data include the locations of currently available parking, the type, and the applicable rate, if requested.
