Keyless web retrieval: search + scrape + dedup, returning the top FULL-TEXT sources for a query WITHOUT writing an answer — so YOU (the calling model) read the evidence and reason over it yourself.

Use this to research a question: call it several times with different focused sub-queries, read the numbered [Source N] blocks it returns, cross-reference them, then write the answer yourself with citations. If the sources don't contain the answer, gather more or say you don't know — do not guess. No API key required.

Args: query: One focused search query (issue several calls for a multi-part question) max_sources: How many sources to return (default 10; bounded to 1-20) chars_per_source: Max characters of text per source (default 7000; bounded to 500-10000) ranker: lexical (default), flashrank (optional extra), or none (retrieval order) render_thin_pages: Send thin-page URLs to Jina Reader (default false)

Return a structured, keyless SourceBundle without synthesizing an answer.

This is the programmatic form of gather_sources, intended for agents and pipelines that need stable evidence identifiers and retrieval provenance. Passage/source relevance defaults to the dependency-free lexical_v1 ranker. FlashRank is optional and falls back to lexical_v1 with an explicit diagnostic. Source quality remains null until a separate quality evaluator computes it. Follow diagnostics.recommended_action; only "synthesize" permits synthesis.

Args: query: One focused search query max_sources: How many sources to return (default 10; bounded to 1-20) chars_per_source: Max characters per evidence passage (default 7000; bounded to 500-10000) ranker: lexical (default), flashrank (optional extra), or none (retrieval order) render_thin_pages: Send thin-page URLs to Jina Reader (default false)

Run a bounded evidence loop while leaving planning and synthesis to the host.

Start with question only. For a complex question, use the returned loop_id and call this tool again with one atomic query. Continue according to next_action. When the returned steps cover the question, call with finish=true and list the synthesis-ready E-step IDs that support the answer. Only status="ready" permits synthesis. Loops expire after ten minutes and allow at most four retrieval calls.

Args: question: Original research question; use only when starting a loop loop_id: Existing loop identifier for a continuation or finish call query: One new atomic retrieval query for an existing loop finish: Validate selected steps and close the loop for synthesis supporting_step_ids: Synthesis-ready step IDs used to finish the loop max_steps: Retrieval budget for a new loop (default 3; bounded to 1-4) max_sources: Sources per retrieval call (default 10; bounded to 1-20) chars_per_source: Characters per evidence passage (default 7000) ranker: lexical (default), flashrank, or none render_thin_pages: Send thin-page URLs to Jina Reader

Quick web search without deep analysis. Returns raw search results.

Args: query: What to search for max_results: Maximum number of results (default 5)

Read and extract clean text content from a URL.

Fetches the page, strips navigation/scripts/ads, and returns the main article or body text. Useful for reading a specific source in detail before or after running research().

Returns the page title, URL, and up to 8000 characters of clean text. Handles retries, anti-bot protection, and Google Cache fallback.

Args: url: The full URL to read (e.g. "https://www.reuters.com/article/...")
