mirrored listing x402 eip155:8453

Combines coordinate-level current weather from Open-Meteo, nearby worldwide METAR observat

Combines coordinate-level current weather from Open-Meteo, nearby worldwide METAR observations and worldwide SIGMETs from the U.S. Aviation Weather Center, official FAA TFR NOTAM polygons with time and vertical limits, plus broader NOTAMs when an authorized official API is configured. FAA TFR coverage is reported separately from full NOTAM coverage. Missing coverage remains unknown rather than falsely clear.
