# Invoke Operation

`POST /v1/op/{operation_id}`

Invoke a kernel operation. Body = the operation's typed input.

Auth is OPTIONAL at the adapter — the kernel's Authenticate stage is the single
enforcement point: it 401s a non-public op with no principal, and lets a public
op through with an anonymous (sharer-attributed) principal.
