Returns the fee and limits of every paid product: the route, the amount range it accepts, the fee rate, and the minimum fee. Free, no auth or payment header, so you can budget before you have an account.

Fees are added on top of amount. The total is amount + max(amount × fee_rate, min_fee), rounded up to the cent. The international card's fee_rate is the rate in effect now, including any running fee promotion. For the exact total of one specific request, read the amount in that route's 402 challenge: requesting a paid route without a payment header returns the quote and charges nothing.
