Description

AI Translation Available

An HTTP endpoint intended for provisioning enterprise and reseller organisations is reachable without any session. The authentication middleware is bound only to an explicit list of controllers, and the enterprise controller is not on that list, so no authentication runs for these routes.

The endpoint's only check is that the request body carries a token bearing a valid signature from the instance secret. It does not check what that token was issued for. Login tokens are signed with the same secret and carry no purpose, audience or expiry claim, so an ordinary user's own session token satisfies the check.

Presented with such a token, the endpoint creates a new organisation holding the highest subscription tier, flagged as lifetime and with a channel allowance far above any sold plan, creates an organisation-owner account alongside it, and returns the new organisation's API key in the response body. That key is immediately valid against the public API.
