Gemstone Suggestion

Endpoint POST https://starsapi.com/api/v3/vedic/predictions/gemstone-suggestion

Returns personalized gemstone recommendations based on the Lagna lord, Yogakaraka, and functional benefics. Each recommendation includes the gemstone, substitute, weight, metal, finger, wearing day/time/nakshatra, activation mantra (English + Devanagari), and step-by-step wearing procedure. Up to 3 stones are recommended; a fallback ensures the response is never empty.

Notes

Selection priority: Lagna lord > Yogakaraka > Functional benefics. Only planets in good dignity (exalted, mooltrikona, own sign, or normal) are eligible.
Fallback logic ensures a non-empty response: if no benefic qualifies, the Lagna lord stone is recommended regardless of dignity, optionally paired with the 9th lord.
Each stone includes both primary gemstone and affordable substitute.
