What the create route takes

What POST /api/v0/assets/create takes beyond its documented body, by capability name. create-idempotency-keys: every server of this Athena honours the create’s Idempotency-Key, so a create whose answer was lost (a timeout, a dropped connection, a gateway’s 502, 503 or 504) may be sent again with the same key and is answered with the asset the first request made. A server names nothing for 30 minutes after it starts, longer than a rollout takes, so a client never sends a create again while a server that would create a second asset can still receive it. The answer says what this Athena’s code does, never anything about you or your data, and is never cached.
