Transportation APIs cover transit schedules, real-time vehicle positions, flight data, fuel prices, and EV-charging locations. Public agencies worldwide publish free GTFS-style feeds, while mobility platforms like Uber and Amadeus operate commercial marketplaces. Real-time endpoints update every few seconds, so cache aggressively and respect published polling intervals.

Start with pricing and auth: free tiers and no-auth APIs are fastest to prototype with. Then check CORS if your app calls the API from the browser, and health before you commit — a great API that's been down for a week will block your launch. Each profile below shows all of these signals plus rate limits where documented.
