The First Professional Human Design API

The BodyGraph calculation involves two moments: (1) Personality side - planetary positions at exact birth time, (2) Design side - planetary positions ~88 days before birth (when Sun is 88° behind natal position).

Our API uses Swiss Ephemeris (NASA JPL DE431 data) for sub-arcminute precision.

Each planet activates a specific Gate (1-64) based on its zodiacal position.

These Gates connect to Centers, forming Channels when both ends are activated.

The result: your unique energetic blueprint including Type (how you exchange energy), Strategy (how to make decisions), Authority (your decision-making center), and Profile (your life role).

Human Design defines 5 energy Types: (1) Manifestors (~9%) - defined Throat connected to Motor center, not Sacral.

Strategy: Inform before acting.

(2) Generators (~37%) - defined Sacral center.

Strategy: Wait to respond.

(3) Manifesting Generators (~33%) - defined Sacral AND Throat-Motor connection.

Strategy: Wait to respond, then inform.

(4) Projectors (~20%) - no Sacral, no Throat-Motor connection.

Strategy: Wait for invitation.

(5) Reflectors (~1%) - all 9 Centers undefined.

Strategy: Wait lunar cycle.

Our API instantly determines Type with the /type endpoint in ~100ms.

We're the only platform combining Human Design with a complete Astrology ecosystem: (1) 100+ Astrology endpoints alongside Human Design, (2) Transit overlays showing real-time BodyGraph activations, (3) Compatibility analysis with scoring system for relationships, (4) AI interpretations via GPT-4/Claude - not static text, (5) 13+ language support vs competitors' English-only, (6) Swiss Ephemeris precision vs simplified calculations, (7) $11/month vs $25-200/month competitors.

Plus: built-in glossaries for Gates, Channels, Types - no need for separate reference data.

Integration is straightforward: (1) Get API key from dashboard (instant, no approval), (2) POST birth data to /human-design/bodygraph endpoint, (3) Receive JSON with complete BodyGraph in <300ms.

Quick endpoints available: /type for Type-only (~100ms), /design-date for Design moment calculation.

SDKs available for JavaScript, Python, PHP, Ruby.

Example use cases: astrology apps adding HD features, dating apps using compatibility, wellness platforms showing daily transits, coaching tools with full BodyGraph analysis.

Our compatibility API analyzes two BodyGraphs for relationship dynamics.

It calculates: electromagnetic connections (where your definitions attract), compromise channels (potential friction points), dominance patterns (who leads in which areas), and composite definition (combined energy flow).

Returns compatibility scores for emotional, mental, and physical connection.

Perfect for dating apps seeking deeper matching than sun signs, coaching platforms analyzing team dynamics, or relationship counseling tools.

Response includes interpretations explaining each connection type.

Transits show how current planetary positions temporarily activate your BodyGraph.

Our /transits endpoint overlays today's gates on your natal chart, showing: which centers are temporarily defined, new channels forming, and how your Type might shift.

Includes 24-hour forecast showing upcoming activations.

Use cases: daily guidance features, tracking specific gates (like Gate 51 for shock/initiation), building transit calendars.

Transit overlays combined with natal charts create personalized daily readings - a key feature for wellness and self-discovery apps.
