# Astrology API Skill

## When to Use

Use this skill when the user asks about:

- Birth charts, natal charts, horoscopes
- Zodiac compatibility, synastry, relationship analysis
- Planetary positions, transits, aspects
- Moon phases, lunar metrics, void of course
- Solar/lunar returns, progressions, directions
- Tarot card readings, spreads, interpretations
- Numerology (core numbers, compatibility, comprehensive)
- Vedic astrology (kundli, doshas, dashas, panchang)
- Chinese astrology (bazi, ming gua, feng shui)
- Human design (bodygraph, type, channels, gates)
- Kabbalah (tree of life, birth angels, gematria)
- Astrocartography (relocation, power zones, lines)
- Fixed stars (positions, conjunctions)
- Eclipses (upcoming, natal impact)
- Palmistry (palm analysis, reading)
- Daily/weekly/monthly/yearly horoscopes
- Career, health, spiritual, psychological analysis
- Chart rendering (SVG, PNG images)

## Prerequisites

Before making any API call, verify:

1. `$ASTROLOGY_API_KEY` environment variable is set
2. `curl` is available on PATH

If the API key is missing, ask the user to set it:

```
export ASTROLOGY_API_KEY="your_token_here"
```

## How It Works

1. **Gather data** from the user depending on the request type:
   - For natal/personal: name, birth date (year, month, day), birth time (hour, minute), birth city + country code (2-letter ISO)
   - For synastry/compatibility: birth data for TWO people
   - For transits: natal data + transit date/time
   - For horoscopes by sign: just the zodiac sign name
   - For tarot: question or spread type
   - For numerology: full name + birth date

2. **Call the API** using `{baseDir}/scripts/astro-api.sh`:

   ```
   bash {baseDir}/scripts/astro-api.sh POST /api/v3/charts/natal '{ ... }'
   ```

3. **Present results** in a human-friendly format, highlighting key findings.

> **Full endpoint reference:** Read `{baseDir}/references/api-endpoints.md` for all 190+ endpoints with detailed parameters.

## Default Options

When the user doesn't specify preferences, use these defaults:

- **House system:** `P` (Placidus) — most common in Western astrology
- **Zodiac type:** `Tropic` (Tropical) — Western standard
- **Language:** `EN` (English) — override based on user's language
- **Tradition:** `universal` — broadest coverage

## Output Format

When presenting results to the user:

1. **Start with the highlights**: Sun sign, Moon sign, Ascendant (Rising)
2. **Use plain language** — translate astrological jargon
3. **Format positions as tables** when showing multiple planets
4. **Highlight notable aspects** (conjunctions, oppositions, squares, trines)
5. **For compatibility**: lead with the overall score/summary
6. **For horoscopes**: present the text naturally, don't dump raw JSON
7. **For chart images (SVG/render)**: save to a file and inform the user

## Edge Cases

- **Birth time unknown**: Use noon (12:00) and note that house positions and Moon degree may be less accurate
- **City not found**: Ask for latitude/longitude instead. Use `latitude` and `longitude` fields instead of `city`/`country_code`
- **API errors (400/422)**: Parse the error message and explain to the user what's wrong (e.g., invalid date, missing field)
- **Large responses**: For analysis reports, summarize the key points rather than showing everything
- **Language support**: The API supports EN, RU, FR, DE, ES, IT, PT, and more — match the user's language when possible
