Amounts and receipts
Amounts are integers in minor units (1500 = 15.00) and currencies are ISO-4217 codes. Every call in this group answers 201 with a receipt `{reference, amount, currency, status}`; the money settles a moment later and the status moves to `completed` (see Transactions). Errors answer 4xx with `{error}`, e.g. `insufficient_funds`, `invalid_amount`, `identity_verification_required`, `cannot_pay_self`.
