  • list_base_rates

    Catalog of all published Quiet Failures base rates: metric id, the global question, the current global figure, sample size, severity, and every published segment slug (valid `segment` values for get_base_rate). Use get_base_rate for full detail on one.

  • find_base_rate

    Search the Quiet Failures base rates by keyword (e.g. "dmarc", "certificate expiry uk", "subdomain takeover"). Returns matching metrics and their most citable segments.

  • get_base_rate

    Full detail for one Quiet Failures base rate segment: the figure with confidence interval, how it is measured, why it matters, the limits of the measurement, the recent time series, and the canonical source URL to cite. Segment defaults to "global"; country slugs (gb, fr, us…) a…

  • check_email_auth

    Live SPF, DKIM and DMARC audit of up to 50 domains the user owns or asks about. Returns a per-domain breakdown plus a portfolio grade. Compare against the base rates: most of the web fails these controls. Rate-limited per client.

  • check_subdomain_takeover

    Live scan of one domain: enumerate its subdomains (CT logs + DNS), then test each for dangling references on 13 cloud providers. Slow on large domains (up to a few minutes). Rate-limited per client.

  • check_whois

    Live WHOIS lookup for up to 100 domains: expiry date, registrar, nameservers. Use to catch registrations about to lapse. Rate-limited per client.
