Data.gov doesn’t just catalog raw data, it also includes APIs from across government. You can browse the current catalog for APIs, but expect this listing to grow as agencies include more of their APIs as part of their data.json metadata in Project Open Data. You can also find an extensive list of Federal Government APIs here on this page. This has been added to the tools section of Research Resources Subject Tracer™ Information Blog. This will be added to Script Resources Subject Tracer™. This will be added to Statistics Resources and Big Data Subject Tracer™.
