Ekadhipatya Reduction

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

Returns Ekadhipatya Shodhana (dual-lordship reduction) for each planet’s BAV, computed on the Trikona-reduced figures using the classical occupancy-based rules. The result is the shuddha (purified) bindus used for Shodhya Pinda. Sun and Moon, owning a single sign each, are exempt; per classical doctrine the reduction applies to each planet’s BAV only, never to the SAV.

Authentication

Method	Example
Header (recommended)	`X-Api-Key: am_live_xxxxxxxxxxxx`

Query	`?api_key=am_live_xxxxxxxxxxxx`

Request body

Field	Type	Required	Description
`name`	string	No	Echoed in the response.
`year`	integer	Yes	Birth year.
`month`	integer	Yes	Birth month, 1–12.
`day`	integer	Yes	Day of month.
`hour`	integer	Yes	Hour, 24-hour.
`minute`	integer	Yes	Minute.
`second`	integer	No	Default `0`.
`latitude`	number	Yes	Decimal degrees.
`longitude`	number	Yes	Decimal degrees.
`timezone`	string	Yes	IANA timezone.
`ayanamsa`	string	No	Default `lahiri`.
`node_type`	string	No	`mean` (default) or `true`.

Response shape

Field	Type	Description
`lordship_pairs`	object	The five same-lord sign pairs: Mars (Aries/Scorpio), Venus (Taurus/Libra), Mercury (Gemini/Virgo), Jupiter (Sagittarius/Pisces), Saturn (Capricorn/Aquarius).
`bhinnashtakavarga.{Planet}.original`	object	Raw BAV per sign.
`bhinnashtakavarga.{Planet}.trikona`	object	After Trikona Shodhana.
`bhinnashtakavarga.{Planet}.ekadhipatya`	object	Shuddha bindus after the occupancy rules.
`bhinnashtakavarga.{Planet}.total_*`	integer	Totals at each stage.

Occupancy rules

For each same-lord pair, examined on the Trikona-reduced figures with planet occupancy (Rahu/Ketu excluded): if either sign has 0 bindus, or both signs are occupied, no change is made. If both signs are unoccupied, both reduce to the lower of the two values (both to 0 when equal). If one sign is occupied and the other is not, only the unoccupied sign is reduced — by the occupied sign’s value when greater, otherwise to 0.

Errors

HTTP	Code	Cause
400	`MISSING_FIELD`	Required field absent.
400	`INVALID_DATE`	Bad calendar date.
400	`INVALID_TIME`	Hour/minute/second out of range.
400	`INVALID_TIMEZONE`	Non-IANA timezone.
400	`INVALID_COORDINATE`	Lat/lon out of range.
400	`INVALID_PARAM`	Bad ayanamsa or node_type.
405	`METHOD_NOT_ALLOWED`	Non-POST request.
