**APIs profiled:** 1

WindBorne Systems operates a global constellation of long-duration Global Sounding Balloons and pairs that proprietary in-situ atmospheric data with WeatherMesh, its AI-based numerical weather forecast model. The WindBorne Data API serves real-time balloon observations, soundings, super-observations, constellation and flight-path metadata, point and gridded WeatherMesh forecasts, tropical-cyclone tracks, and population-weighted heating/cooling degree-day insights. Access is via a Bearer API key over REST, an official Python library and CLI, and a hosted Model Context Protocol server for AI agents.
