Exa

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 for full documentation.

Supports both managed (Lava’s API keys) and unmanaged (bring your own credentials) mode.
