Data Sources, Crawling & Technical Behavior

Last updated: November 4, 2026

Can the API return the final URL after redirects, the retrieval time or cache age, and the original vs. updated publication date?

  • Please see our API documentation at docs.tavily.com for the fields available in each response.

Do results come from Tavily's own crawler or from third-party indexes? Are pages fetched at query time or served from an index?

  • Both. Tavily primarily use it's own index and queries independent third-party indexes only as a fallback when our index can't return what's needed.

Does server-side retrieval block private or internal network destinations and check every redirect (SSRF protection)? Does include_domains limit redirects?
