I'm building an app using a free United States API (no auth needed).

API: Federal Register API ~ US government documents, rules & notices
Provider: U.S. Office of the Federal Register / GPO
Endpoint: GET https://www.federalregister.gov/api/v1/documents.json?per_page=5
It returns JSON.

Source: U.S. Office of the Federal Register / GPO (https://www.federalregister.gov/developers/documentation/api/v1)
Source type: Curated source
Endpoint type: Provider API base URL
Integration difficulty: Copy-paste ready
Last checked: 2026-06-30
Production caveat: Still handle empty rows, schema changes, pagination, stale coverage, and temporary upstream failures.

Help me fetch this and build a simple page that displays it nicely. Include basic production safeguards for errors, empty responses, schema changes, caching, and rate limits.
