Response schema:

   "accounts" : [
         // Balances in dollars
         "availableBalance" : number,
         "currentBalance" : number,
         "createdAt" : date-time,
         "id" : string,
         "status": "active" | "deleted" | "pending" | "archived",

The id field returned here is a valid argument to /accounts endpoints, such as /accounts/:id/transactions, where you can fetch deposits and withdrawals from Treasury.

However, Treasury-specific events, such as dividend payments, price changes, and changes or assessments to a fee schedule are not represented as transactions, and will be available in forthcoming api endpoints specific to Treasury.
