all prices excl. VAT.

### 4.1.1 Subscription duration

Subscriptions are issued on an annual basis and are payable monthly or annually in advance. To ensure uninterrupted service and unless otherwise stated, the subscription will automatically renew for 12 months after expiration. You will receive an automatic notification to a specified email address of your choice when the subscription limit is reached.

### 4.1.2 Soft limit

Exceeding the number of API requests per day over the number of calls included in the subscription is possible and does not lead to an interruption of the service. Excess requests will be charged quarterly for the exact number of calls exceeding the package volume at €X.XXX per call.

### 4.1.3 General

Day is defined as day UTC. Unused API requests are not transferred to the next day.
