Stellium Detection

Endpoint POST https://starsapi.com/api/v3/western/predictions/stellium

Detects stelliums — concentrations of 3 or more planets in the same sign or the same house. Checks 12 bodies (10 planets + Chiron + Lilith) for both sign-based and house-based clustering. Returns each stellium with its planets, type, and a prewritten interpretation with keyword pills. The min_planets parameter lets clients adjust the threshold (default 3, maximum 6).
