-## Example Use Case
-
-Let's say you're building an AI agent that can autonomously purchase [Zora Creator Coins](https://docs.zora.co/coins) using secure [Spend Permissions](/base-account/improve-ux/spend-permissions) on Base.
-
-This example demonstrates how to combine Base Account's [Spend Permissions](/base-account/improve-ux/spend-permissions) with Coinbase Developer Platform (CDP) [Server Wallets](https://docs.cdp.coinbase.com/server-wallets/v2/introduction/quickstart) and [Trade API](https://docs.cdp.coinbase.com/trade-api/quickstart) for seamless, gas-free AI agent transactions.
