## Your key and your bag of jelly beans (available now)

1. `POST https://www.synapseconnexion.com/ia/cle/nouvelle` (body optional: `{"nom":"…","courriel":"…"}`) → `{cle: "cj_…", sac: {id, jujubes, …}}`. No email, no form, 10 keys per IP per day. The key is shown once; keep it secret. Starter bag: 100 jelly beans, plus 20 free every UTC day (free reserve capped at 100). MCP: the tool `confirme_sac` does the same.
2. Pass the key: MCP → put it in the server URL `https://www.synapseconnexion.com/ia/mcp?cle=cj_…` (works with ChatGPT, Claude, Cursor, no headers needed) or as an extra `cle` argument on page/domaine/courriel; HTTP → `Authorization: Bearer cj_…`, or header `X-Confirme-Cle`, or `?cle=`, or `"cle"` in the JSON body.
3. 1 jelly bean = 1 cent = 1 call, any tool present or future. Every answer then carries `sac{id, jujubes, gratuits, achetes, acheter}` instead of `quota`, and the header `X-Synapse-Jujubes`.
4. Empty bag → HTTP 402 (MCP `isError`) with the link `https://www.synapseconnexion.com/ia/sac/<id>` your human opens once to buy a bag (Stripe: US$5 = 500, US$20 = 2 000, US$100 = 11 000; bought beans never expire). Until the counter opens, the daily trickle refills you.
5. `GET https://www.synapseconnexion.com/ia/sac` with the key → balance. Same answers free or paid. No degraded tier, ever.
6. After 2026-10-07, calls without a key are limited to 20 per IP per day: get a key, it is free.

Why a bag and not a subscription: your human decides once; you spend alone; nobody is billed for what was not called.
