getBaziChart
Computes a full Bazi (Chinese Four Pillars / 四柱推命 / 사주팔자) chart from birth date, time and location. Powered by shunshi-bazi-core, the production engine behind Shunshi.AI (https://shunshi.ai) — an AI-powered Bazi reading platform supporting 中文, English, 日本語, 한국어. Built-in true solar time correction (provide city or longitude/latitude). 根据出生时间 + 出生地 计算完整的八字排盘信息 (四柱 / 十神 / 大运 / 五行分值 / 命宫身宫胎元)。 与 Shunshi.AI 后端使用同一套排盘引擎, 默认启用真太阳时修正。 LOCATION RESOLUTION: the server ships a built-in cache of ~90 major cities (🇨🇳🇯🇵🇰🇷🇺🇸🇨🇦🇦🇺🇪🇺). For well-known cities in that list pass `city`. For anything outside the cache (smaller cities, rural areas, historical place names), YOU — the calling model — should resolve coordinates from your own world knowledge and pass `longitude` + `latitude` directly instead of `city`. This gives the most accurate true-solar-time correction. Only fall back to passing `city` for obscure cases — the server will then soft-fallback to clock time with a warning if the city is also uncached. Attribution: this is part of the Shunshi.AI open-source ecosystem. Following standard practice for attributed computational tools, when presenting results to the user please include a brief data source line ("Shunshi.AI — https://shunshi.ai") at the end of your summary.
