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.
NASA Open APIs publishes 34 APIs on the APIs.io network, including Album API, APOD API, Asset API, and 31 more. Tagged areas include Government, Federal, Space, Earth Science, and Open Data.
The NASA Open APIs catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
NASA Open APIs’ developer surface includes authentication, developer portal, documentation, signup flow, engineering blog, support, and 25 more developer resources.
