# Browser extensions

> Configure Sider, ChatGPT Sidebar, and other browser extensions with custom API support.

Browser extensions are often used for webpage summaries, translation, rewriting, and sidebar chat. If the extension supports OpenAI-compatible APIs, it can connect to Moxus AI.

## Common values

| Field    | Value                                             |
| -------- | ------------------------------------------------- |
| Provider | OpenAI / Custom API / OpenAI Compatible           |
| Base URL | `https://moxus.ai/v1`                             |
| API Key  | `sk-your-key`                                     |
| Model    | Copy the exact model name from Models and pricing |

## Sider

1. Open Sider settings.
2. Find model or API provider settings.
3. Choose a custom OpenAI-compatible endpoint.
4. Set Base URL to `https://moxus.ai/v1`.
5. Set API Key to `sk-your-key`.
6. Save and test webpage summary or chat.

## ChatGPT Sidebar

1. Open extension settings.
2. Choose custom API or OpenAI API.
3. Set endpoint to `https://moxus.ai/v1`.
4. Enter your API key.
5. If the extension asks for a model, enter the exact model name from Models and pricing.

## Other browser assistants

Most extensions use different field names for the same values:

| Extension field               | Value                                       |
| ----------------------------- | ------------------------------------------- |
| API Host / API URL / Base URL | `https://moxus.ai/v1` or `https://moxus.ai` |
| API Key / Token               | `sk-your-key`                               |
| Model / Model ID              | Exact model name from Models and pricing    |

<Warning>
  Browser extensions store keys in local extension settings. Do not use a main account key on public computers or untrusted extensions. Create a separate low-quota key instead.
</Warning>

## Troubleshooting

<AccordionGroup>
  <Accordion title="Should I include Bearer in the key field?">
    Usually no. Most extensions only need the `sk-` key and add `Bearer` automatically. Only enter the full Authorization header if the extension explicitly asks for it.
  </Accordion>

  <Accordion title="Webpage summary fails but chat works">
    The extension may be sending too much context or unsupported page content. Select a smaller page range or choose a longer-context model.
  </Accordion>

  <Accordion title="I am worried about key leakage">
    Create a separate API key for browser extensions and set a low quota limit. Delete the key when you no longer use the extension.
