Check the remaining prepaid balance on the account behind the API key, in credits and dollars.
Returns the caller's remaining balance as both `free_balance_credits` (raw integer credits) and `free_balance_display` (a dollar string). The account is identified entirely by the API key, so this endpoint takes no request body. Free. Use it to check funds before a pricier call, or to surface a live balance in your own dashboard.
