Spiritual Intelligence API
Fifteen calculation systems.
One REST API.
Astrology, Human Design, Numerology, Gene Keys, BaZi and more — as precise, documented endpoints for your platform. No ephemeris libraries, no edge cases.
One call. A complete chart.
What normally takes weeks — compiling ephemeris libraries, handling timezone edge cases, validating against reference data — is a single HTTP request.

Built by someone who uses it daily
I'm René — a computer science engineer with 25+ years in requirements engineering and solution design, and a Human Design practitioner. That combination is the point: the API isn't a wrapper someone built from documentation. Every endpoint exists because I needed it for my own readings, reports and clients first.
Building something that needs this data?
The API is in closed beta. Free access while it lasts, all endpoints unlocked, and a direct line to the person who built it.
