电商可以通过使用API接口获取商品信息数据。API是应用程序编程接口的缩写，它允许程序之间进行通信和数据传输。为了获取商品信息数据，电商可以利用API接口向商品供应商的数据库发送请求，然后接收并解析返回的数据。
具体来说，电商可以按照以下步骤利用API接口获取商品信息数据：
1. 找到需要的API接口：首先，电商需要找到支持查询商品信息的API接口。
2. 注册并获取API密钥：在使用API接口之前，电商需要注册并获取API密钥。API密钥是识别电商身份的唯一标识符。每个API接口都有自己的注册、认证和授权过程，因此需要根据提供商的要求执行相应的操作。
3. 发送请求：一旦获取了API密钥，电商就可以利用API接口向商品供应商的数据库发送请求。请求的内容可能包括需要查询的商品、价格、库存等信息，也可能包括其他参数，如时间范围、排序方式等。
4. 解析返回数据：供应商的数据库会返回一个响应，响应通常以JSON或XML格式返回。电商需要使用相应的解析器（如XML解析器或JSON解析器）将响应解读为易于理解的数据格式。然后，电商可以将数据用于网站或应用程序中。
需要注意的是，电商需要确保API接口的使用符合供应商的条款和服务协议。同时还需要确保数据的安全性和隐私性，以避免泄露用户敏感信息或对用户造成损失。
