# How are API calls billed?

API usage is billed by the amount of images **rendered** using [Render API](/api-reference/render-api.md).

`1 rendered image = 1 credit`

Credits are bought through a **monthly** or a **yearly** subscription. Subscriptions also remove watermarks that show on a FREE plan.

Check pricing options by visiting [this link](https://dynamicmockups.com/pricing/).

{% hint style="info" %}
API calls that result in an error will **not** consume a credit.
{% endhint %}

You can track the remaining credits in your [Subscription](https://app.dynamicmockups.com/subscription) page or the sidebar.
