Create a subscription checkout
POST/subscription-checkoutsCreate a single-use intent that authorizes a customer to start a recurring subscription. The merchant declares the per-cycle budget (required) and an optional per-charge cap. Returns a checkout_url — redirect the customer there to complete the subscribe and first-charge flow. No signed request is needed at creation; the customer's on-chain signature authorizes the subscription and first charge atomically.
