What problem does it solve?

FR content is publicly accessible without authentication, enabling programmatic discovery and retrieval of proposed rules, final rules, notices, and related regulatory documents from 1994 to present to support regulatory tracking and compliance research.

Core Features & Use Cases

• Document Search (GET /api/v1/documents.json) with flexible filters and fields to tailor responses for regulatory monitoring and research workflows.
• Single Document Detail and Multi-Document Batch endpoints for rapid lookups, batch processing, and cross-document analysis.
• Faceted Counts and Public Inspection endpoints to summarize content and monitor pre-publication status across agencies.
• Agencies Lookup to obtain agency slugs and metadata for precise scoping of queries.

Typical use cases include tracking open comment periods for procurement rules, researching FAR case histories, and cross-referencing CFR parts affected with docket IDs.
