# 使用 API 密钥

## [Buy API (Postman)](https://www.postman.com/tronsave/tronsave/folder/y222ywm/buy-with-apikey)​

有两种方法可以创建API密钥：

[选项1：在Tronsve网站上生成API密钥。](/chinese/developer/get-api-key/on-the-website.md)

[选项2：在Telegram上生成API密钥。](/chinese/developer/get-api-key/on-telegram.md)

您可以使用API密钥进行:

1. [获取内部账户信息](/chinese/developer/buy-resources-v2/use-api-key/get-internal-account-info.md)
2. [获取订单簿](/chinese/developer/buy-resources-v2/use-api-key/get-order-book.md)
3. [获取估算 TRX (Estimate TRX)](/chinese/developer/buy-resources-v2/use-api-key/estimate-trx.md)
4. [购买能源](/chinese/developer/buy-resources-v2/use-api-key/buy-energy.md)
5. [获取单个订单详情](/chinese/developer/buy-resources-v2/use-api-key/get-one-order-details.md)
6. [获取内部账户订单历史](/chinese/developer/buy-resources-v2/use-api-key/get-internal-account-order-history.md)
