Measured tools (12)

• post_human_design_bodygraph read-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.

  Parameters:

  • date (required) — string — Birth date in YYYY-MM-DD format. The anchor for both the Personality activations at birth and the Design activations 88 degrees of solar arc earlier.
  • time (required) — string — Birth time in 24-hour HH:MM:SS format. Precision matters: the profile lines and gate boundaries shift with the exact minute of birth.
  • timezone (required) — IANA name (e.g. "America/New_York", "Europe/London", "UTC"), decimal hours (e.g. -5 for EST, 1 for CET), or a fixed UTC offset (e.g. "-05:00", "+01:00"). Prefer the IANA name: it is resolved to the offset in force at the birth date and time, historical daylight-saving rules included, while a fixed offset or decimal is taken literally and will be wrong if it does not match the daylight-saving state at that moment. On a transition day a time in the repeated hour is read as its first occurrence and a time in the skipped hour is moved forward past the gap. Invalid timezones return 400 with a validation error.
  • lang — string — Response language (BCP 47). Supported: en, tr, de, es, hi, pt, fr, ru, zh-Hans, zh-Hant. Defaults to en. Coverage varies by domain, and a field with no translation in the requested language returns English.
  • compact — boolean — Set true for the same data in a compact shape: arrays of same-shaped objects arrive columnar as {"__cols":[names],"__rows":[[values]]}. Lossless, typically 40 to 52 percent fewer tokens.
  • latitude — number — Birth latitude in decimal degrees. Optional and does not affect the bodygraph, which depends only on ecliptic longitudes. Defaults to 0.
  • nodeType — string — Lunar node convention. "mean" is the smoothed average node, which always moves retrograde; "true" is the osculating node, which tracks the real perturbed node, oscillates up to about 1.5 degrees either side of the mean on a 173-day cycle, and can briefly turn direct. Neither is more correct and they almost always fall in the same sign. Applies to the North and South Node activations. True is what professional Human Design software uses (HumanDesign.ai, Total Human Design) and is the value RoxyAPI verifies against, so leave it unset for a standard chart. It matters only when a node sits on a gate boundary, where the choice moves a node gate. Because a gate can be half of a channel, that can change the completed channels and, with them, whether a center reads defined or open, plus the definition, authority, profile or type. A chart where only one center disagrees is the usual shape, since the type and profile often survive unchanged. If another calculator disagrees on any of those, it is almost certainly using the mean node: pass "mean" to match it. Defaults to "true".
  • longitude — number — Birth longitude in decimal degrees. Optional and does not affect the bodygraph. Defaults to 0.

• post_human_design_connection read-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. Returns every active gate for each person, including hanging gates, 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.

  Parameters:

  • personA (required) — object — Birth moment of the first person in the connection.
  • personB (required) — object — Birth moment of the second person in the connection.
  • lang — string — Response language (BCP 47). Supported: en, tr, de, es, hi, pt, fr, ru, zh-Hans, zh-Hant. Defaults to en. Coverage varies by domain, and a field with no translation in the requested language returns English.
  • compact — boolean — Set true for the same data in a compact shape: arrays of same-shaped objects arrive columnar as {"__cols":[names],"__rows":[[values]]}. Lossless, typically 40 to 52 percent fewer tokens.

• post_human_design_penta read-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.

  Parameters:

  • members (required) — array — Birth moments of the three to five people in the group. Below three no Penta forms; above five a second Penta emerges.
  • lang — string — Response language (BCP 47). Supported: en, tr, de, es, hi, pt, fr, ru, zh-Hans, zh-Hant. Defaults to en. Coverage varies by domain, and a field with no translation in the requested language returns English.
  • compact — boolean — Set true for the same data in a compact shape: arrays of same-shaped objects arrive columnar as {"__cols":[names],"__rows":[[values]]}. Lossless, typically 40 to 52 percent fewer tokens.

• post_human_design_transit read-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.

  Parameters:

  • birthData (required) — object — Birth moment whose natal bodygraph the transit is overlaid on.
  • date — string — Transit date in YYYY-MM-DD UTC. Optional. Defaults to today in UTC when omitted, giving the just-now transit.
  • lang — string — Response language (BCP 47). Supported: en, tr, de, es, hi, pt, fr, ru, zh-Hans, zh-Hant. Defaults to en. Coverage varies by domain, and a field with no translation in the requested language returns English.
  • time — string — Transit time in HH:MM:SS UTC. Optional. Defaults to the current UTC time when omitted. Precision matters: the Moon moves through a gate in roughly half a day.
  • compact — boolean — Set true for the same data in a compact shape: arrays of same-shaped objects arrive columnar as {"__cols":[names],"__rows":[[values]]}. Lossless, typically 40 to 52 percent fewer tokens.

• post_human_design_variables read-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.

  Parameters:
