Natal-Transit Aspects

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

Computes degree-orb aspects between transiting planets and natal planet positions over a date range. For each aspect found, returns entry, exact, and exit dates. This is a sidereal, orb-based model (5 major aspects) — the Vedic counterpart of the western natal-transit-aspects endpoint.

Natal targets include the 9 classical planets plus chart angles (Ascendant/Lagna and Descendant). Parashari whole-sign has no MC/IC, so those are omitted.

For sign-based Parashari graha drishti between transiting planets (no natal chart), use aspects.

Authentication

Required. See basic → Authentication.

Request body

natal (required)

Birth data for the natal chart:

Field	Type	Required	Description
`year`	integer	Yes	Birth year.
`month`	integer	Yes	Birth month, 1–12.
`day`	integer	Yes	Birth day.
`hour`	integer	Yes	Birth hour (24h clock).
`minute`	integer	Yes	Birth minute.
`second`	integer	No	Default `0`.
`latitude`	number	Yes	Birth place latitude.
`longitude`	number	Yes	Birth place longitude.
`timezone`	string	Yes	IANA timezone of birth place.

Transit parameters

Field	Type	Required	Description
`query_type`	string	No	`range` (default) or `date` (single day).
`start_date`	string	*	`YYYY-MM-DD`. Required for `range`.
`end_date`	string	*	`YYYY-MM-DD`. Max 366 days from start. Required for `range`.
`date`	string	*	`YYYY-MM-DD`. Required for `date`.
`timezone`	string	No	Transit timezone. Defaults to natal timezone.
`ayanamsa`	string	No	Default `lahiri`.
`node_type`	string	No	`mean` (default) or `true`.
`transit_planets`	string[]	No	Filter transiting planets. Default: all.
`natal_planets`	string[]	No	Filter natal targets. Default: all (planets + Ascendant + Descendant).
`orbs`	object	No	Custom orb overrides per aspect type (e.g. `{"conjunction": 8}`).

Response shape

natal_chart

Echo of the computed natal chart with sidereal planet longitudes, signs, and degrees.

Each aspect

Field	Type	Description
`transit_planet`	string	The transiting planet.
`natal_planet`	string	The natal target (planet or angle).
`aspect_type`	string	`conjunction`, `opposition`, `trine`, `square`, `sextile`.
`aspect_angle`	integer	Aspect angle in degrees (0, 180, 120, 90, 60).
`orb`	number	Maximum orb distance (degrees).
`entry_date`	string	When the aspect enters orb.
`exact_date`	string	When the aspect is exact (0° orb).
`exit_date`	string	When the aspect leaves orb.
`is_applying`	boolean	`true` if the transit planet is approaching exact.
`transit_sign`	string	Sign of the transiting planet at exactitude.
`natal_sign`	string	Sign of the natal planet.

Use cases

Personal transit forecast — show which natal planets are being activated by current transits.
Saturn return / Jupiter return — detect when Saturn/Jupiter conjuncts its natal position.
Transit timeline — build a month-by-month aspect calendar for a client.
Push notifications — alert users when a major transit aspect enters orb.

Errors

HTTP	Code	Cause
400	`MISSING_FIELD`	Missing natal birth data field.
400	`VALIDATION_ERROR`	Date range exceeds 366 days, or malformed dates.
400	`INVALID_PARAM`	Invalid `query_type`, `node_type`, or orb values.
500	`CALCULATION_ERROR`	Natal chart calculation failed.
