get_birth_chart
ChatGPTAnalyze a birth chart using Western, Vedic, or Korean Saju astrology. Returns an 8-axis personality radar (Wealth, Career, Health, Love, Family, Mind, Creativity, Spirit) with letter grades (SS/S/A/B/C), plus the tradition-specific birth chart (Western wheel, Vedic grid, or Saju four pillars). Uses Swiss Ephemeris for astronomical precision. All three traditions are calculated — the
system parameter controls which chart format is returned. A cross-system insight from another tradition is included as a teaser. Requires: birth_date (YYYY-MM-DD), birth_time (HH:MM 24h, use '12:00' if unknown), latitude/longitude of birth location, city, country. Timezone is optional — derived automatically from coordinates. System selection: infer from conversation context. 'western' for birth chart / sun sign / horoscope questions. 'vedic' for kundli / rashi / dasha / jyotish. 'saju' for 사주 / sajupuli / four pillars. Default: 'western'. Locale: set 'locale' based on the user's conversation language. 'en' English, 'ko' Korean, 'ja' Japanese, 'hi' Hindi, 'es' Spanish, 'fr' French. Default: 'en'.
