Live airport operational status with weather-driven delay-risk verdict API

Current operational status for an airport (IATA or ICAO code) for travel agents, composed from LIVE keyless aviation weather: the latest METAR observation plus the TAF forecast from aviationweather.gov (NOAA Aviation Weather Center). It parses flight category (VFR / MVFR / IFR / LIFR) from ceiling and visibility, reads surface wind and gusts, scans the TAF for a deteriorating trend, and collapses it all into the read a travel agent actually needs: a 0-100 delay-risk score with a LOW / MODERATE / HIGH / SEVERE band, the specific drivers (low ceiling/visibility, gusty winds, worsening forecast), the parsed conditions, the forecast trend, and a plain-English summary. The value-add: turning raw METAR/TAF fields no LLM can reliably decode into an actionable 'will this airport cause delays right now?' verdict. Answers 'What is the operational status of JFK?', 'Is there a weather delay risk at LHR?', 'What is the flight category at KSFO?', 'Will weather delay flights at this airport today?'.
