• calendar Chinese calendar for a date: lunar date (with leap month), zodiac, day officer 建除, yellow/black path, six-day cycle — computed on Beijing time
• ganzhi Four pillars (BaZi) for a date+hour, returned under BOTH year conventions (Lichun vs Lunar New Year) × BOTH day boundaries (midnight vs 23:00) — differences are
• solar_terms All 24 solar terms of a year with exact Beijing instants. Model: VSOP87D apparent solar longitude + nutation + aberration + ΔT; root tolerance 1e-7 day (~8.6 ms
• sun_position Sun azimuth/elevation for a location and instant (solar compass numeric base): azimuth 0=north clockwise, geometric vs apparent (Sæmundsson refraction) elevatio
• kua_number Ming Gua (Kua number) from birth date + gender, with the Lichun year boundary computed astronomically, five-yellow substitution conventions, and eight favourabl
• flying_star_chart Xuan Kong flying star natal chart: nine palaces with mountain/facing/period stars plus classical pattern labels (e.g. 旺山旺向). Period from a construction date, or

• terrain_white_tiger White tiger elevation check (白虎抬头) from a DEM-derived 360-bin skyline: compares the right (white tiger) vs left (azure dragon) sector elevation within ±45° of t
• replay Verifiability as an API call: recompute a stored request and compare its SHA-256 input digest (JCS-canonicalised) against an expected value — byte-identical rep
