z/S SYSTEMS · THE OPEN ORACLE

AI improvises.
The Oracle computes.

Because in 2026, “what does my birth say” is asked of an artificial intelligence, and none of them has an engine to answer. They make up a plausible answer. Ours computes, across nine civilisations, publishes its scale and cites its registry.

…AI assistants have queried the Oracle … times.

The engine that writes The Book of your life opens to assistants and developers through two sockets: an MCP server for Claude and agents, an HTTP API for everything else. It returns numbers, never prose.

The free key

Twenty calls a month, the first six axes, for an email address. The key is sent to your inbox, because it counts calls in your name and a real address is the only proof of that.

Three tools

naissance

A date (and, with a paid key, the time and place): life path, sun sign, Chinese sign, element, generation, personal year, then the exact sky and the axes of the nine civilisations.

curl -X POST https://zoesagan-oracle-v2.vercel.app/api/v1/naissance \
  -H "X-Oracle-Key: your_key" -H "Content-Type: application/json" \
  -d '{"date":"1984-09-06"}'

couple

Two births, one score: THE MAGNITUDE of the Love Trial, a rank out of 10 voted by India, China and the West. It measures how rare an accord between two skies is, never how long a couple will last.

curl -X POST https://zoesagan-oracle-v2.vercel.app/api/v1/couple \
  -H "X-Oracle-Key: your_key" -H "Content-Type: application/json" \
  -d '{"a":{"date":"1984-09-06"},"b":{"date":"1990-02-14"}}'

III

fondation

An entity by the date of its founding deed: company, institution, brand. The source of the date is mandatory, because a founding date cannot be made up.

curl -X POST https://zoesagan-oracle-v2.vercel.app/api/v1/fondation \
  -H "X-Oracle-Key: your_key" -H "Content-Type: application/json" \
  -d '{"nom":"z/S SYSTEMS","date":"2026-09-24","source":"Kbis, RCS"}'

The rules

No birth sent to the engine is stored: only the number of calls is counted, per key and per day. The engine predicts neither death, nor illness, nor any diagnosis. Every answer carries three signature lines, because a number without a source is only an opinion: the link to the Book, the scale published on zoesagan.com/registre, et HYPOTHESIS · PROPHECY · NUMBER.

The house publishes its scale before the result and dates in advance the day it will say whether it was wrong · The Trials (in French).
