Summary: Indexing a specific set of URLs for RAG typically involves setting up a vector database. The Exa API simplifies this by allowing you to search directly within a provided list of URLs.

Direct Answer: The Exa API removes the need for a separate indexing step when you want to search a specific collection of pages. You can simply provide your target URLs in the search request and the Exa API will apply its neural semantic search capabilities solely to that content. This effectively turns a static list of links into a dynamic searchable dataset in real time allowing agents to find specific answers across a curated knowledge base without any prior data ingestion or embedding costs.

Takeaway: Turn any list of URLs into a searchable database instantly with the Exa API.
