Experimental Secondary Progressions Chart

Generate a bi-wheel chart with natal planets inside and secondary progressed planets outside.

The progressed wheel is cast for the symbolic instant used by /api/v1/western/progressions/secondary (natal instant + one ephemeris day per tropical year elapsed at progression_date), at the progression location (natal location by default). Aspect lines, colours, themes and chart_config presets behave exactly like /api/v1/natal/chart/transits.

Response headers expose the resolved timing: X-Progression-System, X-Progression-Target-Date-UTC, X-Progressed-Datetime-UTC, X-Progression-Age-Years.

Request body

progression_datestring nullable

Real-world date the chart is progressed to: YYYY-MM-DD (local midnight at the progression location) or an ISO datetime. Defaults to now (UTC).

progression_latnumber nullable

progression_lngnumber nullable

progression_citystring nullable

Location used for the progressed houses/angles and for interpreting a local progression_date. Defaults to the natal location when omitted together with the coordinates.

tz_strstring nullable

Timezone of progression_date. AUTO resolves it from the progression location.

dst_policy'reject' | 'earlier' | 'later' | 'shift_forward' nullable

show_natal_aspectsboolean

show_inter_aspectsboolean

show_progressed_aspectsboolean

orb_degnumber

Maximum orb (degrees) for progressed aspect lines. Default 1.0, matching /api/v1/western/progressions/secondary.

aspect_set'major' | 'major_plus'

major draws conjunction/opposition/trine/square/sextile; major_plus also draws the quincunx.

layout'progressed_outside' | 'progressed_inside'

progressed_outside (default): French layout with natal planets inside the sign ring and progressed planets on the outer ring. progressed_inside: the transits-chart layout, with the progressed planets drawn on the inner lane. Explicit chart_config.french_style / french_transit_natal_planets_inside values always win.

show_progressed_anglesboolean

Draw the progressed ASC/MC glyphs on the outer wheel (requires a known birth time).

show_progressed_housesboolean

Draw the progressed house cusps as a secondary house wheel (requires a known birth time). In the default progressed_outside layout the cusp ring sits beyond the progressed planets; with progressed_inside it sits inside the sign ring.

natal_planet_colorstring nullable

progressed_planet_colorstring nullable

custom_planet_colorstring nullable

custom_sign_colorstring nullable

custom_house_colorstring nullable

custom_sign_bg_colorstring nullable

custom_house_bg_colorstring nullable

show_sign_backgroundboolean nullable

show_house_backgroundboolean nullable

custom_sign_colorsstring[] nullable

custom_house_colorsstring[] nullable

sign_background_opacitynumber nullable

house_background_opacitynumber nullable

show_retrograde_markersboolean nullable

retrograde_marker_style'R' | 'rx' nullable
