adsb.lol API
Community-run, fully open ADS-B flight tracking: query live aircraft by hex, callsign, registration, military flag, or lat/lon radius, no key.
adsb.lol is an open-source, community-fed flight tracker that publishes ODbL-licensed live aircraft data through a free REST API. It is designed as a drop-in replacement for the ADSB-Exchange RapidAPI shape, exposing v2 endpoints to fetch aircraft by ICAO hex, callsign, registration, type, squawk, by military/LADD/PIA filters, or within a radius of a point. No API key is required today. Great for keyless flight-tracking skills and bounded-area automations.
Free tier
Free and open (ODbL data). No paid tier. Funded by the community of feeders.Rate limits
Dynamic, based on server load; not published. Heavy or malformed requests return 4xx. The project notes an API key may be required in future (obtainable by feeding data to the network).Auth
