RoxyAPI

RoxyAPI Chinese Astrology API

Calculate BaZi Four Pillars charts, Chinese zodiac signs, and the Chinese lunisolar calendar from any birth moment: year, month, day and hour pillars with hidden stems, Na Yin and Ten God relations, luck pillars, day master strength, and animal compatibility. The school splits that make two calculators disagree are typed parameters rather than hidden defaults, and every chart echoes the conventions it was computed under. Solar terms come back as astronomical instants, lunar dates convert in both directions with leap months placed correctly, and the Tong Shu almanac covers day officers, lunar mansions and date selection. One key covers every RoxyAPI domain, with Remote MCP and typed SDKs.
