account
Get account
Identity, plan, entitlements, and the credential making the call. Call this first: one request tells you everything you are allowed to do, including whether batch creation exists yet (capabilities.batch_creation).
GET/v1/account
Call this first after authentication. It identifies the workspace and reports what the credential and current platform version can actually do.
Requires account:read. It changes nothing and consumes no credits. Check capabilities.batch_creation rather than assuming that upload or translation start is available.
