# 如何设置限制
了解如何在 Oxylabs 控制面板中为您的产品实例设置使用量或支出限额。
限额限制实例可使用的资源量。这样可以防止某个项目用尽你的全部余额。
创建实例时，打开“限额与支出”并启用限额。输入你偏好的限额，然后设置限额类型和周期。限额会根据你选择的周期自动重置，例如，日限额会在 00:00 UTC 重置。
选择当超出限额时会发生什么。实例可以被停用，也可以发送电子邮件，或两者都执行。要通知其他人，请将他们的地址添加为电子邮件收件人。
之后你可以随时返回并编辑限额。打开你的实例并选择 **设置限额**。这会打开一个窗口，你可以在其中启用限额、输入你偏好的限额，并设置限额类型和周期。相同设置也可在以下位置找到 **配置器 → 限额与支出**.
🔎 对于代理，你将以 GB 为单位设置限额。对于 Web API，你将按请求次数设置限额。

## 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/chan-pin-yu-gong-neng/how-to-set-up-limitations.md?ask=&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.
