Instructions
Calculate a full Human Design I Ching hexagram chart from birth data. Returns the person's Type (Generator, Manifesting Generator, Projector, Manifestor, Reflector), Strategy, Authority, Profile (e.g. 1/3, 2/4), defined and undefined Centers, activated Gates and Channels, Incarnation Cross, and both Personality (conscious) and Design (unconscious) planetary positions.
CREDIT COST: 2 credits per call.
Human Design uses two calculation moments: the birth time (Personality) and ~88° of Sun motion before birth (~3 months prior, the Design calculation). The API handles this automatically.
IMPORTANT: The datetime should be in UTC. If you have local birth time, convert to UTC first.
EXAMPLE: Get the Human Design chart for someone born April 15, 1990 at 7:30 PM UTC: datetime='1990-04-15T19:30:00Z', latitude=41.8781, longitude=-87.6298

| latitude | No | Latitude of birth location in decimal degrees (positive = North). | |
| longitude | No | Longitude of birth location in decimal degrees (positive = East). | |
