Tools as reported by the server

• cited_brief
  Answers a question from 1-5 web pages you name. Every claim comes with a verbatim quote that is re-checked on the live page; claims that fail are dropped, and if none pass you are not charged. Price: $0.10 USDC per call (x402).
• check_quote
  Checks whether 1-10 quotes really appear on a web page (ignoring case, spacing, and quote or dash styles) and returns the surrounding text. Use it to catch made-up citations. No AI involved; if the page can't be read you are not charged. Price: $0.01 USDC per call (x402).
• page_text
  Fetches a public web page and returns its title and readable text, without scripts, styles or markup (up to 100,000 characters). If the page can't be read you are not charged. Price: $0.01 USDC per call (x402).
• check_links
  Checks 1-10 URLs: HTTP status, where redirects end, the page title, and a warning when a "200" page is really a not-found page. Use it to catch dead or made-up citations. No AI involved; a dead link is a valid answer, but a request with no usable URL is not charged. Price: $0.01 USDC per call (x402)
• check_doi
  Looks up 1-10 DOIs or arXiv ids: does the paper exist, its title, authors, year and venue, how often it is cited, and whether it has been retracted. Pass the titles you cited to see if they match the real ones. Catches made-up references. No AI involved; if the lookup services are down you are not c
• domain_check
  Domain age and registration facts (created, expires, registrar, status, nameservers) from the registry's RDAP or WHOIS service, plus live DNS (address records, mail servers, SPF, DMARC) and plain flags such as "registered only 9 days ago". Use it to judge how trustworthy a site is. No AI involved. W
• robots_check
  Reads the site's robots.txt and says whether a crawler may fetch a URL (RFC 9309: the longest matching rule wins, Allow wins a tie), with the matching rule, crawl-delay and sitemaps. No AI involved; if robots.txt cannot be read you are not charged. Price: $0.01 USDC per call (x402).
