To use the Brave Search functionality within Quivr, you need to configure the BRAVE_SEARCH_API_KEY in your environment. Here’s how to obtain and set up your API key:

  1. Create a Brave Search Account: Visit Brave Search and sign up for an account if you haven’t already.
  2. Obtain API Key: Once logged in, navigate to the developer settings or API section to generate a new API key for your application.
  3. Configure .env File: Add the following line to your .env file in the root of the Quivr project:
    Replace your_brave_search_api_key_here with the actual API key you obtained from Brave Search.

By configuring the BRAVE_SEARCH_API_KEY, you enable Quivr to perform web searches using Brave Search’s capabilities directly from within the application.
