# 城市

我们支持将IP精准至城市级定位，只需要使用`city参数`。例如：`country-US-city-houston`表示来自美国休斯顿的IP。

我们愿意为全球范围内的任何城市提供支持，但我们不保证在所有城市都设有代理。在大多数热门城市中，我们的覆盖率良好，并且提供了诸多代理选择。

以下是一些城市参数的有效示例：

| 国家-城市  | 国家-城市参数                   |
| ------ | ------------------------- |
| 德国-慕尼黑 | `country-DE-city-munich`  |
| 印度-新德里 | `country-IN-city-delhi`   |
| 泰国-曼谷  | `country-TH-city-bangkok` |
| 韩国-首尔  | `country-KR-city-seoul`   |
| 日本-东京  | `country-JP-city-tokyo`   |

**代码示例：**

使用来自美国休斯顿的随机IP地址对`ipinfo.thordata.com`执行查询

# Agent Instructions: 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:

```
GET https://doc.thordata.com/doc/zh/proxies/residential-proxies/location-settings/city.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
