Sun Sign

Endpoint POST https://starsapi.com/api/v3/vedic/natal/sun-sign

Returns the sidereal Sun sign (Surya Rashi) — the zodiac sign occupied by the Sun at the moment of birth. The sidereal Sun sign differs from the tropical (Western) Sun sign by roughly one sign due to the precession of equinoxes. In Vedic astrology the Sun sign indicates the native’s soul nature, authority, vitality, and relationship with the father.

The response includes the sign (English and Hindi), sign lord, element, quality, and the Sun’s exact sidereal longitude.
