Calculations

Calculate a selected house system

Current unversioned gateway response. Equal and Whole Sign are stable; Placidus, Porphyry, Meridian, Campanus, Regiomontanus, Alcabitius, Koch, Morinus, Topocentric, Sripati, and Vehlow are current opt-in systems that reject undefined geometry without fallback. Regiomontanus, Alcabitius, Koch, Morinus, Topocentric, Sripati, and Vehlow are calculation-only and are not admitted by saved profiles or other chart routes.

Each admitted request reserves one monthly usage unit before route validation or engine work; failed or timed-out admitted attempts are not refunded. Do not automatically retry. Historical mode uses an explicit BCE/CE date object and UT1 conventions. Its response is the versioned historical envelope, not the modern UTC envelope. Read result for calculation fields and metadata for limits and uncertainty.
