# Exa

> Semantic search engine that finds web pages by meaning rather than keywords, with built-in content extraction.

Semantic search engine that finds web pages by meaning rather than keywords, with built-in content extraction. Best for discovering conceptually similar content, research synthesis, and extracting clean text from found pages. Unlike keyword-based engines (Serper, Brave), Exa uses neural embeddings to match intent — ideal when the right search terms aren't obvious.

3 endpoints available through Lava's AI Gateway. See the [Exa API docs](https://exa.ai/docs/reference/quickstart) for full documentation.

<Info>Supports both **managed** (Lava's API keys) and **unmanaged** (bring your own credentials) mode.</Info>
