# API Keys

Use an API key to authenticate requests to the Gateway API.

### Team API Key

Within workspace:

1. Open **Settings**.
2. Select **Teams**.
3. Choose the team you want.
4. Open **API Keys**.
5. Select **Generate API Key**.

Make sure you save this API Key - you won't be able to access it again after closing the dialog.

{% hint style="info" %}
Each team can have its API Key with custom settings: models enabled, fallbacks, etc.
{% endhint %}

If needed, you can rotate the API Key within API keys tab settings. This will rotate the API Key so the old one is deprecated, and you can change it to a new one.

### User API Key

Within workspace:

1. Open **Settings** from the left sidebar.
2. Open **API Keys**.
3. Select **Generate API Key**.

Make sure you save this API Key - you won't be able to access it again after closing the dialog.

{% hint style="info" %}
Your API Key is set with custom settings: models enabled, fallbacks, etc. based on the team settings (made by org owner).
{% endhint %}

If needed, you can rotate the API Key within API keys tab settings. This will rotate the API Key so the old one is deprecated, and you can change it to a new one.

### Requirements

{% hint style="info" %}
API usage requires both a paid subscription and purchased API credits.

API credits are not included in your subscription.
{% endhint %}

## 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://docs.nexos.ai/gateway-api/api-keys.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.
