AviationWeather vs wttr.in
The legacy Text Data Server referenced by the original dataserver URL has been discontinued and replaced by the new Aviation Weather Center Data API, reachable at aviationweather.gov/data/api. It serves worldwide METAR/TAF, US/North-Atlantic PIREPs, global SIGMETs, and CONUS G-AIRMETs (which replaced text AIRMETs in January 2025) in raw text, JSON, GeoJSON, CSV, XML, or IWXXM, with no authentication but a 100-requests/minute rate limit.
wttr.in returns weather reports as ASCII art directly to curl, wget, or a plain browser request, so there's no client UI to build. It's a standalone open-source Go service with plain-text, colorized ANSI, PNG, and JSON output modes, and needs no signup or API key.
