Longevity factors

Marakas, maheshwara, rudra, brahma and the trishoola rasis — the classical longevity indicators. Marakas, maheshwara and rudra are each returned in both of the forms the engine computes, one derived from the chart as a whole and one from the planet positions directly, because the texts disagree about which to use and presenting only one would be taking a side silently. These are house and planet indicators. Nothing here predicts when anyone dies.

Request fields

FieldTypeRequiredNotes
date_timestring (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.

latitudenumber (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 -90 · max 90

longitudenumber (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_floatnumber (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.

keysarrayoptional

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.
