# 基本查詢

基本查詢僅需要輸入`USERNAME`和`PASSWORD`，無需其他任何參數。對於基本查詢，是通過隨機IP地址發送請求，每次新的請求都會使用不同的代理。

**代碼示例**

在下方示例中，通過隨機IP執行對`ipinfo.thordata.com`的查詢

{% tabs %}
{% tab title="cURL" %}

```sh
curl -x t.pr.thordata.net:5555 -U "td-customer-USERNAME:PASSWORD" ipinfo.thordata.com
```

{% endtab %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://doc.thordata.com/doc/zh-hk/dai-li/yi-dong-dai-li/ji-ben-cha-xun.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
