Location No Auth Free & Open location open_data

Space has a hostile radiation environment that increases the risk of cancers in humans and malfunctions in spacecraft electronics. The types of space radiation of primary concern are: Galactic Cosmic Rays from outside our solar system generated by supernovae and other phenomena; Solar Energetic Particles produced by the Sun during intense and sporadic bursts of activity; and Trapped Radiation: energet

What can you build with Space Radiation API?

Space Radiation API is a Location API. Developers commonly use location APIs for:

tracking assets and vehicles in real time
building delivery and logistics apps
finding nearby businesses or services
geo-fencing and location-based notifications
address validation and autocomplete

No authentication required. This API is open — no signup or key needed. Ideal for quick prototypes and public-facing features. Space Radiation API is free to use, making it a low-risk choice to experiment with.
