# API End Points

We've focussed on documenting the following API end points initially:

* [Julian](https://docs.radiantdrift.com/julian-day) to Date; Date to Julian Day
* [Delta T](https://docs.radiantdrift.com/delta-t) for Date
* [Rise/Transit/Set](https://docs.radiantdrift.com/rise-transit-set-times) (Sun, Moon, Galactic Center)
* [Body Position](https://docs.radiantdrift.com/body-position) (Sun, Moon, Galactic Center, or for an arbitrary right ascension and declination)
* [Solar Eclipses](https://docs.radiantdrift.com/solar-eclipses)
* [The Moon](https://docs.radiantdrift.com/the-moon) (libration and lunar limb profile)
* [Geodesic](https://docs.radiantdrift.com/geospatial/geodesic) - calculate points along the great circle between any two points
* [Elevation](https://docs.radiantdrift.com/geospatial/elevation) - elevation at one or more latitude/longitudes, and elevation profiles along an arbitrary great circle

We have a number of other API endpoints just waiting to be documented (you may find them already in our [OpenAPI](https://docs.radiantdrift.com/getting-started/openapi-specification) spec). You can expect to see the following added soon:

* Az/Alt Search - search for a times when a body is at a given azimuth/altitude, or in a certain range of az/alt values
* Celestial Events - Moon phases, solstices, equinoxes, lunar eclipses, solar eclipse general circumstances
* Meteor Showers
* Solar Irradiation - solar intensity, instantaneous irradiation, and daily and monthly clear sky insolation estimates for modules at an arbitrary tilt/azimuth

If you have other APIs you'd like to see, let us know.
