Aspects

Endpoint POST https://starsapi.com/api/v3/transit/vedic/aspects

Computes Parashari graha drishti (sign-based planetary aspects) between all transiting grahas at a given moment. Returns aspects organized both by_source (what each planet aspects) and as a flat aspects list, plus a summary with totals and mutual aspects.

This uses the classical sign-based aspect model (7th for all, plus special aspects for Mars/Jupiter/Saturn) — not a degree-orb model. For degree-orb transit-to-natal aspects, use natal-transit-aspects.

Authentication

Required. See basic → Authentication.

Request body

Field	Type	Required	Description
`latitude`	number	Yes	Observer latitude.
`longitude`	number	Yes	Observer longitude.
`timezone`	string	Yes	IANA timezone.
`year`…`second`	integer	No	Defaults to now.
`ayanamsa`	string	No	Default `lahiri`.
`node_type`	string	No	`mean` (default) or `true`.
`include_nodes`	boolean	No	Include Rahu/Ketu in aspect calculations. Default `true`.

Response shape

planets

Map of planet names to their sidereal longitudes (0–360), used for the aspect calculation.

by_source

Keyed by the aspecting planet. Each entry lists all planets it aspects.

Field	Type	Description
`target`	string	Planet being aspected.
`type`	string	Aspect type: `7th_aspect`, `4th_aspect` (Mars), `5th_aspect` (Jupiter), `3rd_aspect` (Saturn), etc.
`strength`	string	`full` for Parashari sign-based aspects.
`source_sign`	string	Sign of the aspecting planet.
`target_sign`	string	Sign of the aspected planet.

aspects (flat list)

Same data as by_source but flattened. Each object adds source (aspecting planet name).

summary

Field	Type	Description
`total_aspects`	integer	Total aspect count.
`mutual_aspects`	integer	Pairs where A aspects B and B aspects A.

Special aspects (Parashari)

All planets cast the standard 7th aspect. Additionally:

Mars — special 4th and 8th house aspects.
Jupiter — special 5th and 9th house aspects.
Saturn — special 3rd and 10th house aspects.

Use cases

Transit aspect grid — render a planet-vs-planet aspect matrix.
Mutual aspect alerts — highlight powerful mutual aspects between slow planets (Jupiter-Saturn, etc.).
Transit yoga detection — combine aspect data with dignity from advanced to identify transit yogas.

Errors

Same error set as basic.
