-d '{"date_time":"2026-09-01T06:00:00+05:30","timezone_as_float":5.5,"latitude":26.9124,"longitude":75.7873}'Tara bala: which of the twenty-seven birth nakshatras are well placed against the nakshatra the Moon is transiting. Returns the favourable nakshatras grouped by tier along with when the assessment stops being valid - the Moon changes nakshatra roughly every day, so this is a same-day answer. Use it to tell a user with a known birth nakshatra whether today favours them.
| Field | Type | Required | Notes |
|---|---|---|---|
| date_time | string (date-time) | required | The moment to calculate for, ISO 8601. ALWAYS include an offset or a trailing Z - a value with no zone is read as Asia/Kolkata (UTC+05:30), not UTC, and can return the previous day's result with a 200. '2026-09-01T06:00:00Z' and '2026-09-01 06:00:00' are different instants and give different answers. |
| latitude | number (double) | required | Latitude of the place, in decimal degrees. Positive is north, negative is south. Example: 26.9124 for Jaipur, 40.7128 for New York. Minutes and seconds are not accepted - convert first. min -89.9 · max 89.9 |
| longitude | number (double) | required | Longitude of the place, in decimal degrees. Positive is east, negative is west. Example: 75.7873 for Jaipur, -74.0060 for New York. Note the sign: a missing minus puts New York in China. min -180 · max 180 |
| timezone_as_float | number (double) | required | UTC offset of the place, in hours, as a decimal. Example: 5.5 for India (UTC+05:30), -5 for New York in winter, 5.75 for Nepal. This is NOT validated against date_time - if the two disagree you get a successful response for the wrong moment, so derive both from the same source. Use the offset in force on that date, not today's: a summer birth in a country with daylight saving needs the summer offset. min -12 · max 14 |
| dhuma_vyatipata_relation | string | optional | 360_minus_dhumadhuma_plus_53_20 |
| eccentric_anomaly | number (double) | optional | |

| gulika_portion | string | optional | saturneighth |
| gulika_rises_at | string | optional | beginningmiddleend |
| kala_mrityu_rise_at | string | optional | beginningmiddleend |
| keys | array | optional | Which calculations to return, as a list of names. See the key table for this endpoint; an unrecognised name rejects the whole request. One call costs one credit however many keys you ask for, so request everything you need at once rather than making several calls. |

| mandi_rises_at | string | optional | beginningmiddleend |
| mean_anomaly | number (double) | optional | |
