How this service works
Interactive Bitcoin 4-year halving cycle chart on a polar disc. Live price, 200W MA, Mayer Multiple, RSI, MACD, Pi Cycle and optional paid cycle projections.
Output
A JSON object containing a count of aircraft found (capped at 200), an array of aircraft records each with ICAO24 hex address, latitude, longitude, heading in degrees, callsign, on-ground boolean, barometric altitude in meters, and velocity in m/s, plus an attribution string crediting adsb.lol under ODbL 1.0.
Example use cases
Live airspace awareness near airport
“Show me all aircraft currently flying within 100 nautical miles of JFK airport (latitude 40.6413, longitude -73.7781) — I want their callsigns, altitudes, and whether they're airborne or on the ground.”
Drone operator airspace check
“I'm at coordinates 51.5 latitude, -0.12 longitude in central London — are there any aircraft within 50 nautical miles of me right now that I should know about before flying my drone?”
Aviation enthusiast spot tracking
“Can you find all planes within 200 nautical miles of latitude 48.85, longitude 2.35 over Paris and list their ICAO codes, speeds, and headings so I can track interesting flights?”
Technical details
Endpoint
GEThttps://4yearcycle.com/x402/flights?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need live, real-time aircraft positions around a specific geographic point using crowd-sourced ADS-B data from adsb.lol. It is ideal for proximity-based queries (radius search) rather than tracking a specific flight by route or airline. Prefer it over airline schedule APIs when you need actual current positions rather than planned schedules, and over radar apps when you need machine-readable JSON output for programmatic use.
Side effects
- Missing lat or lon parameters returns a validation error
- Radius value above 250 is silently capped at 250 nautical miles
- No aircraft in range returns count 0 with empty aircraft array
- Invalid coordinate format (outside -90/90 or -180/180 range) may return error or empty result
- Payment failure (x402) returns 402 before any aircraft data is returned
