Prastharaka Ashtakvarga

Endpoint POST https://starsapi.com/api/v3/vedic/ashtakvarga/prastharaka

Returns the full Prastharaka spread — the astrologer-grade detail behind every BAV figure: for each sign, exactly which of the 8 contributors (7 planets + Lagna) granted the bindu. Also includes the complete Shodhana pipeline (Trikona and Ekadhipatya reductions per planet) and the final Shodhya Pinda strength values (Rashi Pinda + Graha Pinda), computed by the classical occupancy-based method and verified against standard references.

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
`contributor_order`	array	The 8 contributors: Sun…Saturn, Lagna.
`prastara.{Planet}.total_points`	integer	Planet’s BAV total.
`prastara.{Planet}.spread.{Sign}`	object	`bindus` (count) and `contributors` — 1/0 per contributor showing exactly who granted each point.
`shodhana.trikona.{Planet}`	object	Trikona-reduced figures: `points_by_sign`, `total`.
`shodhana.ekadhipatya.{Planet}`	object	Shuddha bindus after the classical occupancy-based dual-lordship reduction.
`shodhana.shodhya_pinda.{Planet}`	object	`shuddha_bindus` (per sign), `rashi_pinda`, `graha_pinda`, `shodhya_pinda` (= rashi + graha). Used for transit strength and longevity techniques.

Methodology

Trikona Shodhana subtracts the minimum within each trine (1-5-9, 2-6-10, 3-7-11, 4-8-12). Ekadhipatya Shodhana then applies the classical occupancy rules to each same-lord sign pair: pairs where either sign has 0 bindus, or both signs hold planets, are untouched; both-unoccupied pairs reduce to the lower value (to 0 when equal); occupied-vs-unoccupied pairs reduce only the unoccupied sign. Rashi Pinda weights the shuddha bindus by each sign’s classical multiplier; Graha Pinda weights the bindus of each occupied sign by the occupying planet’s multiplier.

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.
