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

1. Call the API using {baseDir}/scripts/astro-api.sh:

```

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

```

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

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
