The service provides listings and locations for stations providing fuel for vehicles powered by technologies other than gasoline and diesel engines. These alternative fuel stations can be rare and widely distributed, making them difficult to find and reducing the appeal of the technologies. The service is intended to counterbalance that effect by publicizing the locations of alternative fuel stops.
API methods support queries against a database of alternative fuel stations. Results can provide either complete listings or the locations of the stations within a particular radius or nearest a location specified by street address, city and state, Zip Code, or latitude and longitude. Returned data provide the station name and location along with particulars like fuel types available and payment methods accepted.
