Endpoint
GEThttps://search.gedx402.com/v1/exa/searchWhen to prefer
Prefer this endpoint when you need semantic or neural web search (not just keyword matching), especially when searching for people, companies, or conceptual topics where meaning matters more than exact terms. Use over Tavily-shaped search when you want Exa's neural ranking specifically, or when retrieving content via URL is needed via the companion /contents endpoint.
