A single endpoint takes a birth date, a place, and a 9-feature body description — and returns the most likely birth-time windows, ranked. Free, open source, and ready to drop into your own app.
/api/Calculate/FindBirthTimeByMachineLearningTopK
Returns a Payload array of ranked candidates, each with a time Range, the
RisingSign at that time, a FinalScore, and the classical body rules that matched.
The server always computes with the RAMAN ayanamsa.
The date and location are known — only the time of day is missing. The time field below is ignored by the API (it scans the whole day).
Nine physical features. Each maps to a classical Vedic rising-sign rule.
Leave blank for the free tier (IP-throttled to 15 requests/min). Add a key for unlimited calls.
