Upcoming

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

A forward-looking, chronologically-merged timeline of upcoming transit and panchang events. Aggregates sign ingress, retrograde stations, combustion windows, nakshatra transits, eclipses, and (when location is provided) panchang events like Ekadashi, Purnima, and Amavasya — all sorted by date into a single stream.

Powers forecast views, transit calendars, and per-user notification feeds.

Authentication

Required. See basic → Authentication.

Request body

Core parameters

Field	Type	Required	Description
`window`	string	No	Preset window: `7d`, `30d`, `3m`, `6m`, `12m`. Default `30d`.
`days`	integer	No	Custom window in days (overrides `window`). Positive integer, capped at ~2 years.
`timezone`	string	No	IANA timezone. Default `UTC`.
`from_date`	string	No	Start date (`YYYY-MM-DD`). Default: today in the given timezone.
`event_types`	string[]	No	Filter to specific event types. Default: all types.
`planet`	string	No	Planet filter or `all` (default).
`include_moon`	boolean	No	Include Moon ingress/nakshatra events. Default `false` (Moon transits are high-frequency).

Location (enables panchang events)

Providing latitude and longitude enables panchang events (Ekadashi, Purnima, Amavasya). Both must be provided together, or both omitted.

Field	Type	Required	Description
`latitude`	number	No	Observer latitude (−90…90).
`longitude`	number	No	Observer longitude (−180…180).

Panchang options

These only take effect when location is provided:

Field	Type	Required	Description
`maas_system`	string	No	`purnimant` (default, North Indian) or `amant` (South Indian).
`tradition`	string	No	`vaishnava` (default) or `smarta`. Affects Ekadashi calculation.
`paksha`	string	No	Filter Ekadashi by `shukla` or `krishna` paksha. Omit for both.

Available event types

Type	Category	Requires location	Description
`sign_ingress`	Planetary	No	Planet enters a new sign.
`retrograde`	Planetary	No	Planet turns retrograde or direct.
`combust`	Planetary	No	Planet enters/exits combustion.
`nakshatra`	Planetary	No	Planet enters a new nakshatra.
`eclipse`	Astronomical	No	Solar or lunar eclipse.
`ekadashi`	Panchang	Yes	Ekadashi tithi.
`purnima`	Panchang	Yes	Full Moon (Purnima).
`amavasya`	Panchang	Yes	New Moon (Amavasya).

Response shape

query

Echo of all resolved parameters including computed to_date and active event_types.

events (chronological)

A flat array of event objects, sorted by date. Every event has at minimum:

Field	Type	Description
`event_type`	string	One of the event type keys above.
`date`	string	Event date (`YYYY-MM-DD`).
`time`	string	Event time (`HH:MM:SS`) in the requested timezone.
`description`	string	Human-readable summary.

Additional fields vary by event type: planetary events include planet and sign/motion details; panchang events include paksha, tithi, and Moon position; eclipses include type and subtype.

Use cases

Transit calendar — render a month-view calendar with all transit events.
Notification feed — power daily/weekly transit alerts for users.
Panchang + transit integration — combine astronomical transits with religious observances in one view.
Forecast reports — generate a “what’s coming” section for transit reports.

Errors

HTTP	Code	Cause
400	`INVALID_WINDOW`	Unrecognised `window` value.
400	`INVALID_EVENT_TYPE`	No valid event types in `event_types` array.
400	`INVALID_PARAM`	Invalid `maas_system`, `tradition`, or `paksha`.
400	`VALIDATION_ERROR`	Latitude/longitude provided without the other.
400	`INVALID_TIMEZONE`	Numeric or non-IANA timezone.

Plus standard auth errors.
