Halowerk Karte Airspace Check
x402
Halowerk Karte Airspace Check is a paid API for AI agents from karte.halowerk.com, paid per call via x402, $0.008/call, status unknown (last checked 2026-10-11).
Checks a coordinate, altitude, and time for current weather (Open-Meteo), nearby METAR observations, worldwide SIGMETs, FAA TFR NOTAM polygons with vertical/time limits, and broader NOTAMs if configured

How this service works
HALOWERK kartenwerk — bezahlte Endpunkte nach x402. Preise in USDC auf Base Mainnet.
Output
Returns current weather data from Open-Meteo, nearby METAR station observations, active worldwide SIGMETs from the AWC, any FAA TFR NOTAM polygons intersecting the queried location/altitude/time with their vertical and time limits, broader NOTAMs if an authorized API is configured, and explicit flags distinguishing FAA TFR coverage from full NOTAM coverage — unknown coverage is reported as unknown rather than falsely clear.
Example use cases
Pre-flight drone safety check
“I'm about to fly my drone at 40.6892° N, 74.0445° W tomorrow at 15:00 UTC — can you check for any active TFRs, SIGMETs, or NOTAMs within 5 km up to 400 feet AGL?”
Event TFR avoidance planning
“There's a large event in Los Angeles this Sunday at 34.0522° N, 118.2437° W — check if any temporary flight restrictions are active between 18:00 and 22:00 UTC within 10 km and up to 3000 meters MSL.”
Aviation weather and SIGMET briefing
“Can you pull current METAR observations and any active SIGMETs near 51.5074° N, 0.1278° W right now, within a 20 km radius, for a flight at 1500 meters MSL?”
Technical details
Endpoint
POSThttps://karte.halowerk.com/v1/airspace-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a unified pre-flight or drone-launch airspace and weather check combining real-time weather (Open-Meteo), METAR, SIGMETs, and FAA TFR NOTAMs in a single call. Prefer it over manual AWC or FAA NOTAM lookups when you need coordinate-precise, altitude-aware, time-specific airspace status — especially for UAV/drone operations or general aviation pre-flight planning at a specific GPS point.
Side effects
- Missing latitude or longitude returns a 400 validation error
- Altitude outside 0–20000m range is rejected
- Radius outside 1–100 km is rejected
- If no authorized NOTAM API is configured, full NOTAM data is unavailable and coverage is flagged as unknown
- AWC or Open-Meteo upstream outages may result in partial data with missing weather or SIGMET fields
- Payment failure via x402 results in 402 response before any data is returned
