Use this when no exact URL is known and current information must be discovered across the public web. Complementary queries may run in parallel when multiple evidence lanes are needed. Stop after an authoritative source answers the question; deepen only for missing or conflicting evidence. For X-only content use x_search. After finding a page whose contents must be verified, call web_fetch with its exact URL. Returns the raw xAI Responses API body.

Use this for current X posts, accounts, threads, replies, and trends. Prefer it over web_search for X content. Complementary X queries may run in parallel. Stop when the requested official post or account result is found; deepen only if evidence is missing or conflicting. If a post links to an external page that must be read, call web_fetch with that URL. Returns the raw xAI Responses API body.

Use this when an exact HTTP(S) URL is known, including URLs returned by web_search or x_search, and the task is to read, quote, summarize, or verify page text. Prefer it over Browser, curl, or shell when no login, click, form interaction, or visual inspection is required. Do not use it to discover URLs. Returns raw Markdown from Jina Reader.
