Free Human Design API with BodyGraph, Types (Generator, Projector, Manifestor, MG, Reflector), and Swiss Ephemeris precision

Looking for a Human Design chart API for developers?

Our BodyGraph API delivers: (1) Send birth data via HTTP, (2) Get Personality + Design (88° solar arc) calculations via Swiss Ephemeris, (3) Full BodyGraph response in <300ms. Free tier: 50 requests/month. Paid from $21/month (Pro Plus), or $37/month Ultra for 11,000 BodyGraphs. Compare to humandesignapi.com ($25-200/mo), humandesignapi.nl (€229-269 one-time), totalhumandesign ($180-220 one-time). The only API combining Human Design with 100+ Astrology endpoints including transit overlays, compatibility scoring, and AI interpretations.

01

How does Human Design BodyGraph calculation work?

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).

What are the 5 Human Design Types?

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.

Human Design Compatibility: How relationship matching works

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.

Human Design Transit Chart: Daily activations explained

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.
