#icao

NATO phonetic alphabet conversion as an API, computed locally and deterministically. The spell endpoint turns any text into the international radiotelephony spelling alphabet used by aviation, the military, emergency services and call centres — letters become Alfa, Bravo, Charlie and so on (case-insensitive), digits use the ICAO forms (Niner for nine), spaces are marked, and unknown characters pass through — so SOS becomes “Sierra Oscar Sierra” and ABC123 becomes “Alfa Bravo Charlie One Two Three”. The decode endpoint reverses it, turning a string of phonetic words back into the original characters and accepting common spelling variants (Alpha or Alfa, X-ray or Xray, Juliet or Juliett, Nine or Niner), flagging any words it does not recognise. Everything is computed locally and deterministically, so it is instant and private. Ideal for aviation, radio, telecom, call-centre, customer-support, accessibility and voice app developers, spelling-out and read-back tools, and IVR systems. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 2 endpoints. This is the NATO/ICAO spelling alphabet; for Morse code use a Morse API.

Resolve and search aircraft type designators — turn the IATA (e.g. 738) and ICAO (e.g. B738) aircraft codes returned by flight-data APIs into readable model names like "Boeing 737-800". Look up by IATA code, ICAO code or name, search 240+ aircraft types, or fetch the whole list. Bundled, fast and always available — a handy companion to flight, airline and airport data.

Search a database of 6,000+ airlines worldwide (OpenFlights open dataset). Find carriers by name and country, look one up by its IATA (2-letter) or ICAO (3-letter) code, and browse counts per country. Each record includes the airline name, codes, radio callsign, country and active status — ideal for travel apps, booking flows, flight dashboards and aviation tooling.

A worldwide airport database in one fast API: roughly 7,700 airports with IATA and ICAO codes, name, city, country, latitude and longitude, altitude and time zone. Look up any airport by its IATA (3-letter) or ICAO (4-letter) code, search by name, city or country, find the airports nearest to any coordinate within a radius (with great-circle distances, optionally only those with IATA codes), or list every airport in a country. Built on the open OpenFlights/OurAirports dataset and served entirely in-memory, so responses are instant and the service is always available. Ideal for travel and booking apps, flight trackers, logistics and routing, maps and location features.
