Felt recently launched its API, receiving over 15,000 calls in just two weeks, and its capabilities were showcased during an internal hackathon with three notable projects. The first project, a live weather map developed by Kyle and Damon, integrates hourly NOAA NOMADS API data with Felt's live data refresh, featuring interactive layers like cloudiness and temperature for real-time weather monitoring. The second project by Tom and Isaac is an interactive map-based adaptation of the 1983 Global Thermonuclear War game, utilizing the API's element creation and webhook features to simulate global strategies, demonstrating the API's potential for building complex applications. Lastly, Chris's elevation profile generator aids route planning by generating elevation profiles for routes using the API's features, exemplified by its application to the Tour de France but applicable to various users needing detailed elevation data. These projects illustrate Felt API's versatility and potential for inspiring future innovations in real-time data integration, interactive gaming, and advanced geospatial analysis.
