API Evangelist Federal Agencies Roundup

Kin Lane's 2026-05-05 roundup at apievangelist.com indexes 211 U.S. federal agencies and their public-facing APIs, RSS feeds, open-data surfaces, and referenced internal systems. Each agency has its own api-evangelist GitHub repo with apis.yml, controlled vocabulary, and where applicable OpenAPI specs. This public-sector topic repo serves as the umbrella catalog binding those agency profiles to the broader federal / state / local / civic-tech landscape.
