# Purchasing API Credits

> How to purchase and manage API credits

API credits can be purchased in one of two ways:

* **Enterprise API plans** – In [**Settings → API**](https://wiza.co/app/settings/api), click **Contact Sales** to inquire about larger credit plans that include volume discounts. Alternatively, you can book directly using [this link](https://schedule.wiza.co/meet/kj-chow/call).
* **Direct purchase via UI** – Use the [slider in the User Interface](https://wiza.co/app/settings/api) to buy smaller amounts of credits. Ensure a valid credit card is on file in the [**Billing**](https://wiza.co/app/settings/billing) tab to process the payment and apply the credits.

<Note>
  API credits have a validity of **12 months**.
