If you've ever tried adding astrology features to an app, you know the pain.
Most APIs on the market give you daily horoscopes for 12 zodiac signs and charge $30+/month for the privilege. Need natal charts? Synastry? Hellenistic techniques? Good luck — you're stitching together 3 different services, writing custom calculation logic, and still getting 2-3 second response times.
We built Astrology API to fix that.
What Astrology API Actually Does
One API. 100+ calculation types. Here's a quick breakdown:
| Category | What You Get |
|---|---|
| Raw Data | Planetary positions, house cusps (23 systems), aspects, lunar metrics, eclipses |
| Chart Analysis | Natal, synastry, composite, transit, solar return, lunar return, progressions |
| Hellenistic | Essential dignities, annual profections, Arabic parts (97+), sect analysis |
| Astrocartography | Planetary lines on world maps, relocation scoring, parans |
| Reports | AI-powered interpretations for natal, synastry, career, life areas — in 9+ languages |
| Horoscopes | Daily/weekly/monthly/yearly — sun-sign AND personalized |
| Numerology | Pythagorean + Chaldean systems, life path, expression numbers |
| Visual Charts | SVG natal wheels, aspect grids, astrocartography maps |
A Quick Example
Get a full natal chart with one call:
curl -X POST https://astrology-api.io/api/v1/natal-chart \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"date": "1990-06-15",
"time": "14:30",
"location": "New York"
}'
That's it. No timezone lookups, no coordinate conversions. Pass a city name — we handle geocoding automatically.
Response time? Under 300ms for this. Competitors typically take 2-5 seconds for the same calculation.

Why Developers Actually Use This
1. Zero Astrology Knowledge Required
Every endpoint has a built-in glossary system. Your frontend devs don't need to know what "annual profections" are — the API returns human-readable labels and explanations alongside raw data.
2. The Documentation Is Actually Good
Interactive API docs via RapiDoc, plus a Postman collection with 113+ pre-built examples. Import it and start testing in 30 seconds.
3. It Scales
No hard request caps that suddenly break your app. Batch processing for bulk operations. Webhook support for async calculations. The architecture handles spikes without you thinking about it.
4. AI-Powered Interpretations
Raw planetary data is great for astrology nerds. But if you're building a consumer app, you need readable content. Our interpretation engine uses LLMs to generate personalized, nuanced reports — not the generic "Mercury is in retrograde" copy-paste.
Who's Using It
- Astrology apps — natal charts, daily horoscopes, compatibility features
- Dating apps — zodiac-based matching and synastry compatibility scores
- Wellness platforms — moon phase tracking, personalized timing recommendations
- Content platforms — automated horoscope content in multiple languages
- Trading tools — yes, really — planetary cycle analysis for market timing
