National Broadband Map is a website providing information about broadband availability throughout the United States. It is a service of the National Telecommunications and Information Administration and part of the State Broadband Initiative, which aims to bring improved broadband and information technology to state and local economies.
The National Broadband Map website was built on a suite of APIs and the suite has been opened for public use. Among the APIs available are the Broadband Provider API and Provider Statistics API, Geography Lookup API, Speed Test API, Wireless Broadband API, and more. Each API is then divided further, for accessing information based on geographic indicators and other parameters. Most APIs are RESTful and return responses in XML and JSON.
