KP House Significators
Computes KP house significators for all 12 houses. For each house returns: occupants (cusp-to-cusp), the sign lord of the cusp, planets in the nakshatra of an occupant, and planets in the nakshatra of the sign lord. Krishnamurti ranks them strongest first as: planets in the star of occupants, occupants, planets in the star of the sign lord, the sign lord; strength_order lists them in that order. all_significators keeps its original order (occupants, sign lord, star of occupants, star of sign lord) and is not a ranking. Planet house is the KP (cusp-to-cusp) house: a planet is in house h from cusp h up to, not including, cusp h+1 of the sidereal Placidus cusps, and a planet exactly on a cusp is in the house that cusp starts (no orb before a cusp). rasi_house is the whole-sign house from the lagna sign. Inside the polar circles, where Placidus cusps do not exist, the request fails with 422 validation_error instead of returning another house system; its details item has type and issue no_quadrant_houses_at_this_latitude and input_format_ok: true (the input is valid; the sky has no Placidus cusps there). Request JSON follows BirthInput: name, date (YYYY-MM-DD), time (HH:MM, required), either location or latitude/longitude/timezone. ayanamsa is accepted but ignored: KP always uses the Krishnamurti ayanamsa.
Request parameters
timezone would give. Use it when the birth record states the offset, or for historical local times the IANA database cannot represent.
