Can I configure the number of search results Exa returns?

Yes, the number of search results is configurable through the `numResults` parameter in your search query.

How does Exa improve code searching?

Exa leverages AI to understand the intent behind your search queries, providing more relevant code examples and documentation compared to traditional keyword-based searches.

What credentials does it need?

It reads `EXA_API_KEY` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.
