`api.idempotency_invalid`

API idempotency is not an Idempotency.

Area 7, HTTP; not declinable; the next step is usually the agent's.

An API that refuses writes without an Idempotency-Key says so with an Idempotency:

example

application {    apis: {        main: {            prefix: /v1            idempotency: true        }    }}
