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. params: none |
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. params: query* |
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…) and company cuts (gb-companies, gb-small…) are also published. params: metric*, segment |
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. params: domains* |
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. params: domain* |
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. params: domains* |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
