POS
The current EXZIX implementation does not expose a merchant POS, branch, terminal or cashier product contract.
Availability
There are no documented or implemented merchant routes for POS sessions, branches, terminals, devices, shifts or cashier identities in the current runtime. This page is an availability boundary, not an API contract.
What remains authoritative
If a merchant builds a presentation or checkout client, it may request a Payment Intent through the documented merchant API. A POS, terminal, branch or cashier cannot confirm a blockchain payment, change Payment Intent status, or bypass merchant ownership, API-key scope, idempotency, observer confirmation or Test/Live separation.
When support is needed
Do not send device secrets, wallet signing material or API keys to support. Provide the request_id, environment, public merchant identifier and relevant Payment Intent public identifier instead.
