API e Astrologjisë

#What the Astrology API does

The Astrology API provides 12 specialized endpoints covering the full spectrum of astrological computation and interpretation. From natal chart calculations with AI-powered readings to raw planetary position data, transit forecasts, synastry compatibility analysis, and detailed lunar metrics — everything an astrology app, horoscope service, or wellness platform needs.

#Endpoints at a glance

#Natal charts & birth data

A natal chart (birth chart) maps the positions of the Sun, Moon, planets, and zodiac signs at the exact moment and location of birth. The natal-chart endpoint calculates all of this and returns both the raw computed data and an AI-generated interpretation.

• Sun sign: Core personality and life direction
• Moon sign: Emotional world and inner self
• Rising sign (Ascendant): How others perceive you (requires birth time)
• Planetary positions: Mercury, Venus, Mars, Jupiter, Saturn, and outer planets
• Aspects: Angular relationships between planets (conjunction, trine, square, opposition, sextile)

#POST /v1/astrology/natal-chart

• Best for: Full birth chart generation with personalized AI interpretation
• Required: birth_date (YYYY-MM-DD)
• Optional: birth_time (HH:MM), location (city name or coordinates), language
• Returns: Computed planetary data + AI reading (sun sign, moon sign, rising sign, key aspects, overall analysis)

#POST /v1/astrology/planetary-positions

• Best for: Raw astronomical data for any date — no AI processing
• Required: birth_date or date (YYYY-MM-DD)
• Returns: Sign, degree, and retrograde status for Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn
• Use case: Build your own chart renderer, populate dashboards, power custom interpretations

#Transit forecasts

Transits describe the current movement of planets through the zodiac and how they interact with natal chart positions. The API provides two categories: generic transits (by zodiac sign) and personalized natal transits (compared to your birth chart).

#Generic transits (by sign)

These endpoints produce horoscope-style readings for a zodiac sign. No birth data needed — just pass the sign parameter.

• daily-transit — Today’s forecast covering love, career, and energy level
• weekly-transit — Week overview with highlights, best day, and challenge day
• monthly-transit — Month outlook with career, love, health themes and key dates

#Personalized natal transits

These endpoints compare current planetary positions against your actual natal chart for highly personalized readings. They require birth_date at minimum.

• natal-daily-transit — Exact transit-to-natal aspects for today, with the most significant aspect highlighted
• natal-weekly-transit — Day-by-day personalized outlook for the coming week
• life-forecast — Long-range forecast covering 3 to 12 months with monthly themes and key periods

#Synastry & compatibility

The synastry endpoint compares two natal charts to analyze relationship compatibility. It calculates cross-aspects between both charts and produces numerical scores alongside AI-powered interpretation.

• Cross-aspects: How Person A’s planets interact with Person B’s (conjunctions, trines, squares, etc.)
• Scores: Overall compatibility, romance, communication, and longevity scores (0–100)
• Interpretation: AI reading of strengths, challenges, and practical advice
• Required: birth_date_a and birth_date_b

#Data-only vs AI-powered endpoints

#Real-world use cases

#Daily horoscope app

Challenge: Serve personalized daily horoscopes to millions of users
Solution: Use daily-transit for generic forecasts (cache per sign per day), and natal-daily-transit for premium personalized readings

#Dating app compatibility

Challenge: Show astrological compatibility between matched users
Solution: synastry endpoint returns scores for romance, communication, and longevity — perfect for compatibility badges and detailed reports

#Wellness & planning platform

Challenge: Integrate moon phase data into a wellness/gardening/planning app
Solution: moon-calendar for monthly views, moon-phase for today’s widget, lunar-metrics for detailed astronomical data

#Content generation

Challenge: Generate weekly astrology content for a blog or newsletter
Solution: Loop through 12 signs with weekly-transit or monthly-transit, use the language parameter for multilingual publishing

#Best practices

1. Cache generic transits: Daily/weekly/monthly forecasts are the same for all users of a sign — cache them aggressively
2. Always send birth_time when available: Rising sign and house placements make readings significantly more accurate
3. Use data-only endpoints for dashboards: planetary-positions, moon-phase, and lunar-metrics are fast and cheap
4. Batch moon calendar requests: One moon-calendar call covers up to 31 days, avoiding repeated single-day lookups
5. Use the language parameter: AI endpoints support multilingual output — generate readings in the user’s locale
6. Handle rate limits: Implement exponential backoff for 429 responses
7. Store birth data securely: Birth date + time + location is sensitive personal data — encrypt at rest

#Error handling

• 401: Invalid or missing API key
• 402: Insufficient credits
• 422: Missing required parameters or invalid format (e.g. invalid date, unknown sign)
• 429: Rate limit exceeded
• 500: Server error (retry with exponential backoff)

// Common error responses
