Moon Sign

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

Returns the Moon sign (Chandra Rashi) — the sidereal zodiac sign occupied by the Moon at the moment of birth. In Vedic astrology the Moon sign is often considered more important than the Sun sign: it governs the native’s emotional nature, mind, and is the basis for horoscope predictions, dasha analysis, and transit readings.

The response includes the sign (English and Hindi), sign lord, element, quality, and the Moon’s exact longitude. For the full nakshatra breakdown (deity, symbol, pada), call /natal/nakshatra.
