The Calculation Layer, Bundled for Builders

The hard part of any serious esoteric product is not the interface — it is the maths: accurate ephemeris positions, house systems, Human Design bodygraph logic, numerology reductions, destiny-matrix arcana. The Esoteric Developer Bundle gives you all of that behind a single API key, so you can build your own apps, bots and sites on engines that already produce correct, defensible output.

What’s Inside

· Natal Chart engine — planetary positions, houses, aspects (Swiss-ephemeris-grade).

· Human Design engine — full bodygraph: type, authority, centres, channels, gates.

· Numerology engine — Pythagorean and Chaldean reductions, personal cycles.

· Destiny Matrix engine — 22-arcana chart with positional interpretations.

· Tarot engine — deck logic, spreads and draw endpoints.

Who It’s For

Developers and studios building metaphysical products who want to ship on a stable calculation core rather than reverse-engineer ephemeris tables. One key, one set of docs, consistent output shapes across every engine.

Licensing
