get_human_design_centers_idread-only | Look up the static reference data for one of the nine Human Design centers by its id: the display name, whether it is a motor or awareness center, and what it means both defined and undefined. A pure reference endpoint with no birth data required. |
get_human_design_gates_numberread-only | Look up the static reference data for a Human Design gate by its number from 1 to 64: the gate keynote name, the center it sits in, the matching I-Ching hexagram, and the gates that form a channel with it. A pure reference endpoint with no birth data required. |
post_human_design_bodygraphread-only | Generate a complete Human Design bodygraph from a birth date, time, and timezone. Returns the energy type, strategy, inner authority, signature, not-self theme, profile, definition, incarnation cross, all nine centers with defined state and active gates, the defined channels, and all 26 planetary activations across the Personality and Design sides. The single endpoint for a full chart in one call, built for Human Design apps, readings, and coaching tools. |
post_human_design_centersread-only | Calculate the state of all nine Human Design centers for a birth moment: whether each is defined or open, whether it is a motor or an awareness center, its theme, and the active gates it holds. The data layer behind a rendered bodygraph where defined centers are colored and open centers are white. |
post_human_design_channelsread-only | Calculate the defined channels for a birth moment. A channel is defined when both of its gates are activated, and it wires together the two centers it connects. Returns each defined channel with its gates, name, circuit family, and connected centers, plus the full set of centers those channels define. Built for bodygraph rendering and definition analysis. |
post_human_design_connectionread-only | Calculate a Human Design connection chart by overlaying two bodygraphs. For each of the 36 channels the dynamic between the two people is classified as electromagnetic, dominance, compromise, or companionship, the four mechanics of how two designs meet. Also returns the nine centers as defined or open in the combined bodygraph with which person defines each, the combined definition, and a count of each dynamic. Built for relationship, dating, and coaching tools. |
post_human_design_gatesread-only | Calculate the 26 gate activations for a birth moment, split into the 13 conscious Personality activations at birth and the 13 unconscious Design activations 88 degrees of solar arc earlier. Each activation reports the planet, gate, line, gate keynote, and the matching I-Ching hexagram. Built for activation columns and detailed chart views. |
post_human_design_pentaread-only | Calculate the Human Design Penta (BG5, Base Group 5) for a small group of three to five people. The Penta is a trans-auric form built from a fixed set of six channels running only between the Sacral, the G Center, and the Throat. It reports which of the twelve Penta gates are filled and by whom, which of the six channels are defined Strengths, the upper leadership channels versus the lower generative channels, the 2/14 material core, and the functional gaps where no member supplies a role. Built for team, family, and group analysis tools. Below three people no Penta forms and above five a second Penta emerges, so the group size must be three to five. |
post_human_design_profileread-only | Calculate the Human Design profile for a birth moment: the conscious Personality Sun line over the unconscious Design Sun line, with the keynote for each. The profile is the geometry of the life role, for example 5/1 the Heretic Investigator. Verified against NASA JPL Horizons positions. |
post_human_design_transitread-only | Overlay the current or any given planetary positions on a natal Human Design bodygraph to see which channels the transit temporarily completes. Returns the 13 transiting body activations with gate and line, the channels the transit completes beyond the natal definition split into personal channels where the transit supplies the partner gate of a natal gate and educational channels where the transit supplies both gates, the natally open centers those channels temporarily define, and a short factual summary. A transit is a single moment, so there is no Design side. When date and time are omitted the overlay is computed for now in UTC. Built for daily Human Design apps, transit widgets, and notification tools. |
post_human_design_typeread-only | Calculate the core Human Design identity from a birth moment: the energy type, the aura strategy, the inner authority, the signature and not-self themes, and the profile. The fast lookup for type-and-authority features without the full bodygraph payload. Verified against NASA JPL Horizons positions. |
post_human_design_variablesread-only | Calculate the four Human Design Variable arrows for a birth moment: Determination and Environment on the design side, Perspective and Motivation on the personality side. Each arrow returns its Color, Tone, and Base numbers from the hexagram-line substructure, the left or right direction set by the Tone, and the sourced Color and direction labels. This is the advanced Rave Variables and Primary Health System layer beneath Type, Strategy, Authority, and Profile. Color, Tone, and Base shift with tiny differences in birth time, so each arrow carries a confidence flag that turns false near a Color or Tone boundary, and a precise birth time is essential. Built for Human Design apps offering PHS, diet, environment, and Rave Psychology readings. |
