Asteroid Astrology API

Calculate the natal positions of the four classical asteroid goddesses, Ceres, Pallas, Juno, and Vesta, for any birth moment. Each asteroid returns its tropical zodiac sign, degree, house placement, daily speed, retrograde status, and a plain language interpretation of its meaning in the chart. Chiron is available through the natal chart endpoint, so this endpoint stays focused on the four asteroid goddesses for natal reports and relationship astrology.
