Tools
| Tool | Description | Behaviour |
|---|---|---|
| bob_extract | 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. Use it when you need the page's own words; use bob_summarize for a short version. Pages that need a login cannot be read; long pages are cut at 8,000 characters and flagged truncated. Each call needs an x402 payment; if the page cannot be read or the URL is invalid, it fails and you are not charged. | Read-only |
| bob_factcheck | 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. Use it to verify a specific statement; use bob_research for open questions. Check one claim per call, phrased as a plain statement such as 'The Eiffel Tower is in Berlin'; split a compound claim into separate calls. Each call needs an x402 payment; if it cannot answer in time or the input is invalid, it fails and you are not charged. | Read-only |
| bob_research | Answers one open research question from the live web with a short written answer and source URLs, usually in 4 to 9 seconds. Use it for a synthesized answer; use bob_search for raw links or bob_factcheck to verify a claim. Works best with one specific question, e.g. 'How do facilitators settle x402 payments?'; several questions per call tend to get one blended answer. Returns {answer, sources}. Needs an x402 payment per call; if it cannot answer in time or the input is invalid, you are not charged. | Read-only |
| bob_search | Runs a web search and returns ranked results as {query, results: [{title, url, snippet}]}. Use it for raw links to read yourself; use bob_research 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. | Read-only |
| bob_summarize | 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. Use it when you want the gist; use bob_extract to get the page's own text instead. Pages that need a login cannot be read. Each call needs an x402 payment; if the page cannot be read in time or the URL is invalid, it fails and you are not charged. | Read-only |
