# Overview

> Issue and manage virtual cards, inspect transactions, and fund card accounts.

The Cards API lets you issue virtual cards, configure spending limits and 3DS behavior, fund cards via a holding account, and retrieve transaction history.

All endpoints are authenticated with the `x-api-key` header. Read operations typically require access level 1; write operations require access level 2 or higher, and sensitive operations (freeze, PIN update) require access level 3.

<Note>The minimum deposit amount for Cards is **10 USD**.</Note>
