Fetch one web page through the stealth browser and return clean, grounded content with provenance.

Hidden text injected for models but invisible to humans is stripped by default and reported in threats. Use this to ground answers in live web content, including sites that block plain fetchers.

Reads a URL you already have: use search to find URLs, or research to search and read in one call. Fetches are rate limited per domain (5s apart by default), so several pages from one site are not instant.

Search the web and return ranked passages drawn from several sources.

One call does what search + repeated read_url would: finds pages, reads them through the stealth browser, and returns the passages most relevant to query — each attributed to its source, with that source's provenance receipt and any stripped injection payloads. A source that fails is reported in sources rather than failing the whole call.

Prefer read_url when you already have the URL, and search when you only want links. This reads max_sources pages, rate limited per domain, so it is the slowest of the three and the one to avoid for a single known page.

Search the web and return ranked hits (title, url, snippet, engine).

Not for reading: it returns links, never page content. Use read_url for one known URL, or research when you want the answer rather than the links.

Use this to find pages, then pass the URLs you want to read_url for safe, grounded content. Results come from a self-hosted SearXNG instance when SEARXNG_URL is set, otherwise from a search page rendered through the stealth browser. Hits are links only — nothing is fetched until you ask.

Check whether Groundhog can reach the stealth browser. Call this to diagnose setup before fetching: if browser_reachable is false, follow hint to start the browser, then retry.
