Vextorium Airport Distance Calculator
x402
Vextorium Airport Distance Calculator is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-15).
Calculates the straight-line distance, approximate flight time, bearing, and CO2 emissions between two airports identified by IATA or ICAO code.

How this service works
Great-circle distance between two airports by IATA or ICAO code in km, miles and nautical miles, bearing, approximate flight time and estimated economy-class CO2 per passenger.
Output
Returns a JSON object with full metadata for both origin and destination airports (IATA, ICAO, name, city, country, region, lat/lon, altitude, type, regular flights flag), plus computed values: distance in km, miles, and nautical miles; approximate flight time in hours; initial bearing in degrees; and estimated CO2 per passenger in kg. Includes a note that the straight-line distance is typically 3–8% shorter than the actual route.
Example use cases
Flight carbon footprint estimator
“I'm planning a trip from London Heathrow (LHR) to Tokyo Narita (NRT) — can you tell me the distance in km and the approximate CO2 emissions per passenger for that flight?”
Airline route planning distance check
“We're evaluating a new route between Dubai (DXB) and São Paulo Guarulhos (GRU) — what's the straight-line distance in nautical miles, the initial bearing, and the approximate flight time?”
Travel time comparison between airports
“How does the flight distance and estimated travel time from Chicago O'Hare (ORD) to Sydney (SYD) compare to flying from Los Angeles (LAX) to Sydney (SYD)?”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/airport-distance?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, structured, pay-per-call airport distance data including CO2 estimates and bearing without relying on a full flight search API. Ideal for agents that need geospatial aviation data without flight availability or pricing — e.g. carbon calculators, route planners, logistics tools, or travel apps needing distance enrichment. Prefer over generic geocoding APIs when the inputs are airport codes and aviation-specific output (nautical miles, bearing, CO2) is needed.
Side effects
- Unknown or invalid IATA/ICAO code returns an error or null airport metadata
- Missing required origin or destination field returns a 400 validation error
- Ambiguous airport identifier may resolve to the wrong airport
- CO2 and flight time values are estimates and may not reflect actual airline routing
