answers 402

Build the full per-period amortization schedule for a fully-amortizing loan. Each row reports the period number, payment, the principal vs. interest split for that payment, and the remaining balance after that payment. Use this when the user wants to see how interest tapers over the life of the loan, or to model an extra-payment scenario by reading the balance at any period.

We sent a real POST request to this endpoint and it answered 402 with payment requirements we could parse.
