# City

Traffic routed through this parameter is billed at double the standard rate

Add a `city` parameter to narrow down to city-level targeting. 

For example, `cr.es;city.madrid,barcelona` means that a proxy from Madrid, Barcelona, and Spain will handle the query. 

Here are a few examples of valid combinations of country and city parameters:

`cr.de;city.berlin`

`cr.br;city.salvador`

**Code example**

In this example, a query to gw\.dataimpulse.com is performed from an IP address from Berlin, Germany:

```
curl -x "http://login__cr.de;city.berlin:password@gw.dataimpulse.com:823" https://api.ipify.org/
```

We cannot guarantee the availability of proxies from a specific city at any given time. However, most popular cities are well covered.

{% hint style="info" %}
It's important to note that selecting a country is mandatory to specify city, state, ZIP code, and ASN targeting.
{% endhint %}

***

You can now exclude specific cities using the `nocity` parameter.

**Example:** To target Germany but exclude Berlin, use:

`cr.de;nocity.berlin`

{% hint style="info" %}
Traffic routed through the `nocity` parameter, as well as `city` parameter is billed at double the standard rate.
{% endhint %}

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.dataimpulse.com/proxies/parameters/city.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
