Solar Return Chart Data Endpoint #

POST /api/v5/chart-data/solar-return #

View Complete Example

Calculates the Solar Return chart for the return happening on or after the specified date, without generating an SVG chart. The Solar Return occurs when the Sun returns to the exact same ecliptic longitude as in the natal chart.

Search parameters (provide year or iso_datetime):

• year (integer, required unless iso_datetime is set): Calendar year to search for the next return (1-3000).
• month (integer, optional): Month (1-12) to start the search from. Requires year.
• day (integer, optional): Day (1-31) to start the search from. Defaults to 1. Requires month and year.
• iso_datetime (string, optional): ISO 8601 formatted datetime to start the search from. E.g. "2025-05-01T00:00:00+00:00". Alternative to year/month/day.

Return-specific options (optional):

• wheel_type (string): "dual" (default) or "single".

  • "dual": Returns both natal and return charts (bi-wheel data model with first_subject and second_subject).
  • "single": Returns only the return chart (single chart data model with subject).

• include_house_comparison (boolean): Include house overlay comparison for dual wheel. Default: true. Automatically set to false when wheel_type is "single".

• return_location (object, optional): Override the location for the return chart. If omitted, the natal subject’s location is used.

  Field	Type	Description
  city	string	Target city name. Falls back to natal city if omitted.
  nation	string	Two-letter ISO country code. Falls back to natal nation if omitted.
  longitude	float	Longitude (-180 to 180).
  latitude	float	Latitude (-90 to 90).
  timezone	string	IANA timezone identifier.
  altitude	float	Altitude in meters.
  geonames_username	string	GeoNames username to resolve location from city/nation.

  Provide all three of latitude, longitude, and timezone for offline mode, or use geonames_username for online resolution.

Computation options (optional, at request body root level):

• active_points (array of strings): Override which celestial points are included. See Active Points.
• active_aspects (array of objects): Override which aspects are calculated and their orbs. See Active Aspects.
• distribution_method (string): "weighted" (default) or "pure_count".
• custom_distribution_weights (object): Custom weights map for weighted distribution.
