NASA Open APIs
NASA Open APIs is the National Aeronautics and Space Administration's unified, public developer portal exposing space, earth science, planetary, heliophysics, and bioscience datasets at api.nasa.gov. A single API key issued through api.data.gov authenticates the family of APIs including APOD, Asteroids NeoWs, DONKI, Earth, EONET, EPIC, Exoplanet Archive, InSight, Mars Rover Photos, NASA Image and Video Library, TechPort, TechTransfer, SSD/CNEOS, Satellite Situation Center, GeneLab, TLE, and the Vesta/Moon/Mars Trek WMTS services. Together with 617+ open-source repositories on github.com/nasa they represent one of the most comprehensive open federal API surfaces in the world. As a US federal civilian agency NASA's data and software products are generally in the public domain, supporting a global ecosystem of researchers, educators, developers, and citizen scientists.
