Coverage and Scope
Occult API computes deterministic systems from a birth moment, a date, or a question, and serves all of them on one key. This page is the boundary.
Why a system may be absent
Two reasons:
1. It is licensed. Some modern systems are copyrighted works owned by a living author or publisher, licensed only through that publisher. Occult API does not serve those.
2. It is not built. Some traditional systems carry no licensing question and are simply not in the catalog today. Chakra systems and runes sit here.
Gene Keys
Occult API does not serve Gene Keys. Gene Keys is a copyrighted body of work by Richard Rudd, published by Gene Keys Publishing Ltd. The published terms allow commercial use only under a formal licence covering teaching and referral rather than redistribution through software. No endpoint returns a hologenetic profile, the Shadow, Gift and Siddhi naming, the spheres, or the sequences.
The hexagram layer underneath IS computable. Gene Keys, Human Design and the I Ching all read the same 64 hexagram wheel. Occult API computes that layer with Occult Ephemeris, verified against NASA JPL Horizons. POST /human-design/bodygraph returns gates with ichingHexagram data. GET /iching/hexagrams/[number] returns the full reading.
Dreamspell and the 13 Moon calendar
Occult API serves the classical Maya day count only. The Mesoamerican domain is built and served: Tzolkin day signs, Haab year, Calendar Round and Long Count. What is not served is Dreamspell (13 Moon calendar), which freezes its count on 29 February and has drifted from the classical count. No endpoint returns a Dreamspell kin number, galactic signature, tone, or 13 Moon date.
POST /mesoamerican-astrology/mayan/chart returns the classical count with conventions naming the correlation constant used.
No prakriti questionnaire
Occult API serves the Ayurveda that is computed, and nothing that asks a user about their own body. The Ayurveda API is built and served: vata, pitta and kapha constitution from a verified sidereal birth chart, dinacharya day from real sunrise, ritucharya season from real solar ingress. What is not served is a questionnaire that infers constitution from answers about a body. The constitution call takes birth data and nothing else.
POST /ayurveda/constitution returns the reading with meta.disclaimer for general wellness, not medical advice.
Frequently asked questions
Does Occult API have Gene Keys? No. Copyrighted work, registered trademark, formal licence required.
Can I build a Gene Keys style profile from Occult API data? Yes, the calculated layer (gate, line, hexagram) from POST /human-design/bodygraph. Any naming layer on top is yours to license.
Why do the gate and line in my chart match my Gene Keys profile? Same calculation. Both read the 64 hexagram wheel from the same two moments.
Why does my Mayan sign differ from a 13 Moon app? Two different counts. Occult API runs the classical Maya day count; Dreamspell freezes on 29 February.
What other systems does Occult API not cover? Traditional systems not built include chakra systems and runes. Any modern system whose text and terminology are owned and licensed by a publisher is out of scope.
Does Occult API reproduce copyrighted interpretation text? No. Every interpretation is written for Occult API and checked against named authorities.
What if I need a system you do not cover? Ask. Contact with the system and what you are building.
