Check Twilio balance from API

Does anyone know how to programmatically check account balances in Twilio (via API)? Was it not implemented?

How do I check twilio usage?

Twilio's Usage page can be found in Console using the following methods: Access the Usage page directly at twilio.com/console/usage. Click View all product usage from the Billing Overview page's Usage Summary module.

Is twilio an API?

Twilio, as an API company, provides many different APIs to our customers to help them build applications that communicate.

You can get Twilio Account details and then make a request to get balance using subresource_uris.balance from Account response

{
  "status": "active",
  "subresource_uris": {
     ...
     "balance": "/2010-04-01/Accounts/ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX/Balance.json"
  },
  "type": "Full",
  ...
}
