A Korean Saju (사주) and Chinese BaZi (八字) four pillars calculator: give it a birth date and time and get a full structured reading back — four pillars, Five Elements, Ten Gods, luck cycles, and daily/annual fortune — as clean JSON, in batch, with zero external API calls (pure computation, runs entirely on Apify's cloud). Ideal as a Saju / BaZi / four-pillars-of-destiny API for astrology apps, fortune-telling sites, and data pipelines.

Built and maintained by KunStudio (also publishers of the Saju API on API.market, Zyla, and RapidAPI, and sajuapp.app).

Input

{
"births": [
{ "year": 1990, "month": 5, "day": 15, "hour": 14, "gender": "male", "label": "me" }
],
"include": ["pillars", "elements", "yongsin"],
"language": "en"
}
  • births — array (max 1000). year 1920–2050, month 1–12, day 1–31, hour 0–23 (omit or -1 if unknown → defaults to noon), gender male/female.
  • include — sections to return; empty = all.
  • language — label language for the Five Elements block (en/ko/ja/zh). Raw Korean/Hanja keys are always present.

Solar (Gregorian) calendar input; the engine converts to lunar internally.

Output

One dataset item per birth record. Invalid records return { ok: false, error } instead of failing the whole run, so a batch of 1000 never dies on one bad row.

Pricing

Pay-per-result: you are charged once per successfully analyzed birth record. No subscription, no free-trial trap — pay only for what you compute.
