Germany Payments (Mollie — Klarna / SEPA)

Create a payment link in EUR for Germany via Mollie. Buyer pays with cards, PayPal, Klarna, SEPA bank transfer, and other methods enabled on the Mollie account. Returns a hosted checkout URL the buyer opens to pay — payment completes automatically, no confirm step. Bring your own credentials via HTTP header (x-mollie-api-key; free test credentials from my.mollie.com never move real money). Money always flows buyer→Mollie→merchant; this service never touches funds.

Check whether a Germany payment (created by create_payment_link) has been paid. Queries Mollie directly — pull-based, no webhook needed. paid=true when status is PAID.

Refund a paid payment (created by create_payment_link). Full refund by default; pass amount for a partial refund where supported. Refunds respect the same owner policy guardrails (x-agentpay-max-amount) as payments — the amount is checked before anything is sent to the gateway.
