# 使用 API 密钥

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/rest-api-v0/buy-on-rest-api/use-api-key/get-internal-account-info.md)
2. [获取订单簿](/chinese/developer/rest-api-v0/buy-on-rest-api/use-api-key/get-order-book.md)
3. [获取估算 TRX (Estimate TRX)](/chinese/developer/rest-api-v0/buy-on-rest-api/use-api-key/use-signed-transaction.md)
4. [购买能源](/chinese/developer/rest-api-v0/buy-on-rest-api/use-api-key/buy-energy.md)
5. [获取单个订单详情](/chinese/developer/rest-api-v0/buy-on-rest-api/use-api-key/get-one-order-details.md)
6. [获取内部账户订单历史](/chinese/developer/rest-api-v0/buy-on-rest-api/use-api-key/get-internal-account-order-history.md)

## **使用API密钥购买能源流程**

## **步骤 1：创建内部账户并存入资金**

* 创建一个内部账户。
* 将TRX存入内部账户。

[按照完整的指南获取API密钥](/chinese/developer/get-api-key.md)

### **步骤 2：检查账户信息**

* 使用[获取内部账户信息 API](/chinese/developer/rest-api-v0/buy-on-rest-api/use-api-key/get-internal-account-info.md)验证您的账户余额和状态。

### **步骤 3：检查可用能源**

* 调用[获取订单簿 API](/chinese/developer/rest-api-v0/buy-on-rest-api/use-api-key/get-order-book.md)查看系统中可用的能源数量。

### **步骤 4：估算所需的TRX**

* 在[获取估算 TRX API](/chinese/developer/rest-api-v0/buy-on-rest-api/use-api-key/use-signed-transaction.md)中输入所需的能源数量和租赁时长，以计算所需的TRX。

### **步骤 5：执行购买交易**

* 将计算出的TRX金额输入[创建订单 API](/chinese/developer/rest-api-v0/buy-on-rest-api/use-api-key/buy-energy.md)并发送请求。

### **步骤 6：检查订单详情和历史记录**

* 使用[获取单个订单详情 API](/chinese/developer/rest-api-v0/buy-on-rest-api/use-api-key/get-one-order-details.md)查看您的购买详情。
* 使用[获取内部账户订单历史 API](/chinese/developer/rest-api-v0/buy-on-rest-api/use-api-key/get-internal-account-order-history.md)检查您的交易历史记录。
