Accounts API

The Accounts API is the public identity and account query surface. Market makers and ISV/IB partners use it to learn who they are trading as and which accounts they can use.
Account creation is not a public REST call. ISV/IB trading accounts are provisioned when KYC is approved — see Accounts. Market-maker accounts are provisioned during onboarding.

User vs Account

A user can have multiple accounts (e.g., for different strategies or purposes).
