Trikona Reduction

Endpoint POST https://starsapi.com/api/v3/vedic/ashtakvarga/trikona-reduction

Returns Trikona Shodhana (trine reduction) for each planet’s BAV — within each trine (1-5-9, 2-6-10, 3-7-11, 4-8-12) the minimum of the three signs is subtracted from all three. The first of the two classical reductions on the path to Shodhya Pinda. Per classical doctrine the reduction applies to each planet’s BAV only; the SAV is never reduced.
