The Data APIs provide programmatic access to select data sets.
About the Data APIs
To use the APIs, you must register for a key at api.data.gov. Registering is simple—just provide your name and valid email address. You’ll gain universal access to any Open Government data using the service, and receive notification of updates and new releases.
After obtaining your key, get the ARMS API.
Getting started with the Data APIs
Code snippets for the ARMS API are available in R (or REST).
