要开发一个API数据接口用于抓取淘宝详情页的商品信息，包括优惠券信息、券后价、销量等参数，通常需要以下步骤：

  1. 需求分析: 确定你需要抓取哪些具体的数据，例如商品名称、价格、销量、优惠券信息等。

  2. 环境准备: 准备好开发环境，如安装所需的开发工具和库。

  3. 注册开放平台账号: 注册并创建应用以获取必要的API密钥（Api Key和Api Secret）。

  4. 选择API: 根据需要选择淘宝提供的相关API。

  5. 调用API: 使用API密钥调用淘宝的接口，发送HTTP请求获取数据。

  6. 解析数据: 处理返回的JSON或XML格式的数据，提取所需信息。

  7. 数据存储: 将解析后的数据存储到数据库中。

  8. 接口封装: 将上述逻辑封装成自己的API接口，供前端或其他服务调用。

  9. 测试: 对API接口进行测试，确保数据的准确性和接口的稳定性。

  10. 部署上线: 将开发完成的API接口部署到服务器上，使其可以处理实际的请求。

  11. 文档编写: 编写API接口的文档，说明如何调用接口、参数含义以及返回数据的格式。

以下是一个简单的API请求演示示例，假设我们使用Python的requests库来调用淘宝的API接口：

# coding:utf-8
"""
Compatible for python2.x and python3.x
requirement: pip install requests
"""
from __future__ import print_function
import requests
# 请求示例 url 默认请求参数已经做URL编码
url = "https://item_get_app/?key=<您自己的apiKey>&secret=<您自己的apiSecret>&num_iid=10335871600"
headers = {
    "Accept-Encoding": "gzip",
    "Connection": "close"
}
if __name__ == "__main__":
    r = requests.get(url, headers=headers)
    json_obj = r.json()
    print(json_obj)

请注意，以上代码仅为示例，实际开发中需要根据开放平台的具体API文档来调整URL、参数和数据处理逻辑。此外，由于淘宝API可能涉及到反爬虫策略和频率限制，你可能还需要处理这些情况。
