## Pricing

from $30.00 / 1,000 calculations

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.

## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js/docs.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python/docs.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## Korean Saju (Four Pillars) Calculator

**Turn a birth date and time into a precise Korean Saju (사주 / BaZi) chart — deterministic, astronomically grounded, no LLM guesswork.** Returns the four pillars plus five elements, ten gods, sinsal, and luck cycles as clean structured JSON.

Large language models are unreliable at this exact task — computing the ganzhi calendar, solar-term boundaries, true solar time, and lunar leap months. This Actor does it **correctly**, using real astronomical calculation (Meeus algorithms), so agents and apps can offload it with confidence.

### What it does

- 🎴 **Four Pillars (연·월·일·시주)** — heavenly stems, earthly branches, hidden stems
- 🌗 **True solar time correction** — longitude + equation-of-time, historical Korea timezones (incl. 1908/1954 offsets, DST periods)
- 🔮 **Full analysis** — five elements (오행) %, ten gods (십성), strength (신강/신약), useful god (용신), interactions (형충회합), sinsal (신살)
- 📅 **Luck cycles** — great luck (대운), yearly (세운), monthly (월운)
- 🌙 **Solar & lunar input** — including leap months
- 🧮 **Deterministic** — same input, same output; correctness is the moat, not an LLM

### How to use

Provide the birth details; get the full chart back as a dataset item.

```json
{
  "calendar": "solar",
  "y": 1990, "m": 5, "d": 16,
  "hour": 9, "minute": 30,
  "gender": "F"
}
````

### Input

| Field | Type | Description |
|---|---|---|
| `calendar` | enum | `solar` (default) or `lunar` |
| `y` `m` `d` | integer | Birth year (1900–2100), month, day |
| `hour` `minute` | integer | Birth time, 24h (default 0) |
| `gender` | enum | `M` or `F` (sets luck-cycle direction) |
| `isLeap` | boolean | Lunar leap month (음력 윤달) |
| `longitude` | integer | Birthplace longitude for true-solar-time (default 127 ≈ Seoul) |

### Output

A dataset item with the full chart:

```json
{
  "출생": { "입력": "...", "진태양시": "09:02 (경도보정 −32분 · 균시차 +4분)" },
  "명식": { "일간": "辛(음금)", "연주": { ... }, "월주": { ... }, "일주": { ... }, "시주": { ... } },
  "분석": { "오행": [...], "십성": [...], "신강약": {...}, "용신": "토(土)", "신살": [...] },
  "대운": { ... }, "세운": { ... }, "월운": [ ... ]
}
```

### Pricing

**Pay per event** — $0.03 per successful calculation. Failed inputs are not charged.

### Use cases

- Power a **saju / fortune-telling app** with an accurate calendar engine (no reimplementation)
- Give an **AI agent** a reliable tool for Korean birth-chart data instead of hallucinating pillars
- Generate structured saju data for **research, content, or personalization**

### FAQ

**Why not just ask an LLM?** LLMs routinely get ganzhi, solar-term boundaries, true solar time, and leap months wrong. This is deterministic astronomical computation.

**What range is supported?** Lunar↔solar conversion is reliable for 1900–2100.

**Is the output in Korean?** Yes — the chart uses standard Korean myeongri terminology (한자 + 한글). Downstream translation/narration is up to the caller.
