### 基于信用额度的计费如何运作？

了解基于信用额度的计费如何运作。&#x20;

您支付的一切 **都通过一个信用余额进行结算**。以下是其运作方式，以及如何随着需求变化进行调整。

使用基于信用额度的计费时，您购买的是一个方案，即固定美元金额的订阅。该金额会添加到一个单一信用余额中，并在您所有自助产品之间共享。您无需为每个产品分别订阅，而是从一个余额中为 [住宅代理](https://developers.oxylabs.io/products/proxies/residential-proxies), [数据中心代理](https://developers.oxylabs.io/products/proxies/datacenter-proxies), [Web API](https://developers.oxylabs.io/products/web-api), [网页解锁器](https://developers.oxylabs.io/products/web-unblocker), [Agent Browser](https://developers.oxylabs.io/products/headless-browser)以及其他产品。

* 您方案中设定的金额会在每个计费周期全额扣费并添加到您的余额中。
* 您在使用时，会按照各产品的费率扣除信用额度。
* 未使用的信用额度会在周期结束时过期，不会自动结转，升级时除外（见下文）。
* 使用自助产品需要有效方案；在评估期间，欢迎信用额度除外。

在以下位置跟踪您的余额、支出和使用情况： **计费与支出** 在仪表板中。

# 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 by asking a question.

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

```
GET https://developers.oxylabs.io/help-center/cn/ji-fei-yu-fu-kuan/gou-mai-chan-pin.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.
