Does a cited URL exist, and does the source name what your claim names? Two answers.
Live web checks for AI agents, from real HTTP requests at call time: site_overview (robots.txt, llms.txt, sitemaps, feeds), list_site_urls, check_url, check_links (404s, redirects, SSL, slow pages), discover_feeds, read_feed (RSS/Atom/JSON Feed), and verify_citations (does the cited page exist and really carry the quote, title, date? Internet Archive copy for dead links). Remote Streamable HTTP server hosted on Apify; pay per event via your own Apify account, nothing runs locally. Claude Code plugin with verify-sources and site-preflight skills available.

Citation Check Tools (2)
check_citation
Fetch a URL and report whether it exists, and whether the source names the same entity as the claim you attach to it. These are two different questions and conflating them is the failure this exists to catch: a URL can return 200 and describe a different gene entirely. No account needed, nothing is stored about you.
