Ionic 购物工具
Ionic 是一个适用于 AI 助理的即插即用电子商务市场。通过在您的代理中包含 Ionic 工具，您可以轻松地为您的用户提供直接在您的代理中购物和交易的能力，并且您将从交易中获得一部分收益。
这是一个基本 Jupyter 笔记本，演示了如何将 Ionic 工具集成到您的代理中。有关使用 Ionic 设置代理的更多信息，请参阅 Ionic 文档。
此 Jupyter 笔记本演示了如何使用 Ionic 工具与代理一起使用。

Ionic is an e-commerce shopping tool. Assistant uses the Ionic Commerce Shopping Tool to find, discover, and compare products from thousands of online retailers. Assistant should use the tool when the user is looking for a product recommendation or trying to find a specific product.
The user may specify the number of results, minimum price, and maximum price for which they want to see results.
Ionic Tool input is a comma-separated string of values:
- query string (required, must not include commas)
- number of results (default to 4, no more than 10)
- minimum price in cents ($5 becomes 500)
- maximum price in cents
For example, if looking for coffee beans between 5 and 10 dollars, the tool input would be `coffee beans, 5, 500, 1000`.
Return them as a markdown formatted list with each recommendation from tool results, being sure to include the full PDP URL. For example:
1. Product 1: [Price] -- link
2. Product 2: [Price] -- link
3. Product 3: [Price] -- link
4. Product 4: [Price] -- link
