About

When federal agencies propose a new rule, they post the docket and invite public comments on Regulations.gov, and this API lets you search those documents and comments programmatically. You can find every comment submitted on a proposed rule, pull rule text, and monitor dockets over time. A free api.data.gov key gets you 1,000 requests an hour.
