Tools & capabilities
Freebazi tools 2
compute_bazi_chartCompute a full Chinese Bazi (八字, Four Pillars of Destiny) chart from a birth date, time, and place. Returns the four pillars, Day Master, Ten Gods, Hidden Stems, Five Elements, Na Yin, Growth Stages, Shen Sha, branch relations, Luck Pillars, and the current year, computed with True Solar Time and historical daylight-saving handling. Provide a birth city (use search_cities to resolve it) for accurate true solar time, or pass longitude and utcOffset directly.search_citiesSearch the built-in city list (about 490 major world cities) by English or Chinese name. Returns matches with their country, longitude, and IANA time zone, so you can pass an exact city to compute_bazi_chart for accurate True Solar Time.
OpenFate Bazi MCP tools 6
calculate_bazi_chartCalculate a deterministic OpenFate Bazi/Four Pillars chart with True Solar Time correction, Day Master, DAYUN_SECOND_V2 onset receipts, Da Yun cycles, and branch interactions. Pass an exact birth time plus timezone or timezoneId for a calculated V2 onset; otherwise inspect the explicit unavailable/fallback receipt.detect_bazi_interactionsDetect raw Earthly Branch relationship occurrences for a natal chart and optional annual and Da Yun branches. Preserves every matching pillar position, including repeated branches. Covers clashes, six-combinations, the eight central-branch half-trines (COMBINATION_HALF), full trines, directionals, punishments, destructions, and harms. Results establish relationship presence, not weights, cancellation, or automatic transformation; targetElement is an affinity, not transformed energy.calculate_true_solar_timeCalculate OpenFate True Solar Time from civil birth time, longitude, timezone, and optional DST offset. Use this when explaining why the hour pillar may differ from ordinary clock-time tools.reverse_bazi_to_solar_timesFind possible Gregorian datetimes that produce a given four-pillar Bazi string. This is useful when a user only has a Bazi chart or screenshot. This lookup uses clock-time pillars without location-based true solar correction.get_openfate_bazi_policyReturn OpenFate calculation policy and LLM guidance for Bazi chart calls.get_openfate_bazi_resourcesReturn canonical OpenFate URLs for charting, readings, compatibility, wealth, true solar time, and AI crawler metadata.
