Answers one open research question from the live web in at most 80 words with up to 3 source URLs, returned as {answer, sources}, usually in 4 to 9 seconds. Use it for a synthesized answer; use web.search for raw links or research.factcheck to verify a claim. Name the people, places and dates the question depends on, and ask one question per call: several in one call get one blended answer. Read-o

Checks one factual claim against the live web and returns {verdict, explanation, sources}, where verdict is supported, contradicted or unclear, usually in 4 to 9 seconds. Write the claim as a plain statement such as 'The Eiffel Tower is in Berlin' and split a compound claim into separate calls. Use research.answer for open questions. For several claims, call once per claim. Read-only. Paid per cal

Condenses one public web page into an 80-word summary with up to 4 key points, returned as {url, summary, key_points}, usually in 3 to 6 seconds. The page is fetched live, so the summary reflects it now; pages behind a login or paywall may return little. Pass the address of the specific page, not a site's home page. Use page.extract for the page's own text. Read-only. Paid per call with x402; if t

Runs a web search and returns ranked results as {query, results: [{title, url, snippet}]}. Use it for raw links to read yourself; use research.answer for a written answer. Plain phrases work as well as keywords; since and until (YYYY-MM-DD) limit results to a publish-date range, which suits recent news. Needs an x402 payment per call; if the search fails or finds nothing, you are not charged.

Returns the main text of one public web page as clean markdown, unchanged and not summarized, up to 8,000 characters, as {url, markdown, truncated}, usually in 2 to 5 seconds. Pass the address of the specific page, not a site's home page; pages that need a login cannot be read, and longer pages are cut and flagged truncated. Use page.summarize for a short version. To read several pages, or to craw

Returns recent news on one topic, person, company or event as {query, window_days, summary, developments: [{headline, date, source}]}: a summary of about 50 words and up to 4 dated developments, newest first, usually in 3 to 7 seconds. A short topic or name works better than a full question; days sets the look-back from today (1 to 30, default 7), so a quiet topic needs a larger value. Use web.sea

Builds an evidence brief for a prediction-market question (Kalshi, Polymarket or similar) from the live web: {question, as_of, summary, evidence_for, evidence_against, key_dates, resolution_notes, sources}, usually in 5 to 8 seconds. Pass the question as the market words it, including its date or threshold (for example 'by Dec 31, 2026' or 'above 4.5%'). It reports evidence and what decides resolu

Returns a short sourced brief on one company as {company, summary, what_it_does, facts, recent, sources}, usually in 5 to 8 seconds. Pass a website address such as stripe.com to avoid name clashes; a bare name resolves to the best-known company with that name and the summary says when the name is ambiguous. Facts such as founding year, location, size, funding or leadership appear only when the sou
