Overview
The NextBus XML feed API provides US transit data — agencies, routes, and predictions (per the docs PDF).
⚠️ Status (verified 2026-08): a guessed path (
/api/public/agencies) returned HTTP 404 (the site serves a frontend) — the XML feed routes differ. Check the NextBus XML feed docs for current paths.
