Tools
| Tool | Description | Behaviour |
|---|---|---|
| contextfetch_answer | Answer a question with passages quoted verbatim from the web, never generated: searches, scores every passage of the top pages with a cross-encoder and returns the best ones with [n] citations to their sources. Use it for quick factual lookups; the quotes may not fully answer an open-ended question. Costs $0.001 ($1 per 1,000). | Read-only |
| contextfetch_auto_reload | Turn auto top-up on or off, or change it: when the balance drops below `threshold_usd`, the saved card adds `amount_usd`, up to `monthly_max_usd` per month. Needs an API key and a card saved at checkout. The monthly cap cannot be raised above $500 here. | Changes data |
| contextfetch_balance | Show the API key's balance in dollars, daily burn rate (7-day average) and auto top-up settings, including the last auto-reload error if a payment failed. Needs an API key (Authorization: Bearer); free. | Read-only |
| contextfetch_crawl | Crawl one website from a start URL and get its pages as Markdown: same-site links only, up to `max_depth` hops (<= 3) and `limit` pages (<= 50). Pass `query` to rank the pages by relevance and return only their relevant passages. Costs $0.001 per page returned ($1 per 1,000). | Read-only |
| contextfetch_deep_research | Deep research in one call, no LLM: a deep search of the question, its sub-topics (or your sub_queries) as searches of their own, and the pages its list and index results link to, returned as one cited report: summary, key facts, a section per sub-topic and the sources, every passage quoted verbatim with [n]. Costs $0.003 a report ($3 per 1,000). For a quick evidence pack use contextfetch_research. | Read-only |
| contextfetch_extract_url | Fetch a public web page (docs, articles, GitHub files, arXiv papers) as clean Markdown with tables preserved. Pass `query` to get only the passages relevant to it instead of the whole page. | Read-only |
| contextfetch_find_similar | Find pages similar to a given URL (alternatives, related docs, competing libraries), excluding the source domain. Returns titles, URLs and the most relevant passages as Markdown. | Read-only |
| contextfetch_get_free_key | Get a free ContextFetch API key (no signup, no payment) with a $2.50 starter balance, for when the keyless daily limit runs out. One key per network, ever: keep the key it returns and use it as `Authorization: Bearer <key>`. | Changes data |
| contextfetch_map | List a website's URLs without fetching its pages: its sitemaps (from robots.txt, else /sitemap.xml) plus the start page's links, same site only, up to `limit` (<= 5,000). Use it to find the right pages before contextfetch_extract_url or contextfetch_crawl. Costs $0.001 ($1 per 1,000). | Read-only |
| contextfetch_research | Research a question in one call, server-side: runs up to 5 web searches (sub-queries) concurrently, dedupes the pages by URL, ranks them all against the question with a cross-encoder and returns one Markdown evidence pack with numbered [n] sources and their query-pruned passages, quoted verbatim (no generated text). Costs $0.001 per sub-query that runs ($1 per 1,000). Pass your own `sub_queries` (distinct angles on the question) for better coverage; if omitted they are derived from `query`: the query, query + "documentation", and query + "benchmark" (speed or comparison questions) or + "example". | Read-only |
| contextfetch_search | Search the web and get LLM-ready Markdown. Each result has its title, URL and only the passages relevant to the query (cross-encoder pruned context), so it costs far fewer tokens than raw pages. Use for current events, documentation, APIs, research and fact checking. | Read-only |
| fetch | Fetch the full text of a search result by its id (a URL). Returns {id, title, text, url, metadata} as JSON. | Read-only |
| search | Search the web. Returns {results: [{id, title, url}]} as JSON; pass an id to `fetch` for the page text. | Read-only |
