Kit Rx

Company card for a domain or name. From Wikidata: QID, label, description, websites, inception, industries, headquarters, country, latest employee count, parent organizations, stock listings and tickers, founders (names only), legal form, LEI. From GLEIF when an LEI is known or a legal name matches exactly: legal name, jurisdiction, entity and registration status, legal and HQ city/country, parents. With match method and confidence. Sources: Wikidata, GLEIF (CC0). Price: $0.01 per successful call, paid in USDC with x402 v2; failed calls and calls that match nothing are not charged.

Current DNS records for a hostname from Cloudflare DNS over HTTPS: A, AAAA, CNAME chain, MX with priority and null-MX flag, NS, TXT (up to 25 records of at most 400 characters, email addresses redacted), CAA as flag, tag and value, and SOA primary nameserver, serial and timers, each with its minimum TTL. An optional type parameter limits the answer to one record type. For subdomains without their own zone, NS and SOA come from the registrable domain. Price: $0.003 per successful call, paid in USDC with x402 v2; failed calls and calls that match nothing are not charged.

Email authentication posture of a domain from DNS (Cloudflare DNS over HTTPS): MX records and null MX, SPF parsed into mechanisms with its all qualifier and a recursive DNS-lookup count against the RFC 7208 limit of 10, DMARC policy (p, sp, pct, alignment, report addresses' domains), MTA-STS and TLS-RPT records, and BIMI. DKIM is not assessed because selectors cannot be enumerated. Returns an A-F grade and 0-100 score with weighted reasons. Price: $0.003 per successful call, paid in USDC with x402 v2; failed calls and calls that match nothing are not charged.

Due-diligence report on a website, merchant or counterparty domain: registrable domain, registry RDAP facts (registrar, abuse contact, created, expiry, age, status, nameservers), DNS records (A, AAAA, MX, NS, TXT, CAA) from Cloudflare DNS over HTTPS, SPF and DMARC posture, a live web probe (redirect chain, HTTPS, HSTS, site-supplied title, parked or for-sale signs), brand-impersonation checks, and a 0-100 risk score with transparent weighted signals and a verdict. Price: $0.01 per successful call, paid in USDC with x402 v2; failed calls and calls that match nothing are not charged.

No registrant contact data. Registries whose terms bar reuse (Nominet, CentralNic, Google Registry) are not queried.

Checks an email address without sending mail: syntax rules (IDN domains in punycode and Unicode), MX records by preference, null MX (RFC 7505), implicit A/AAAA fallback, NXDOMAIN, SPF and DMARC policy, disposable, role, free-webmail and +tag flags, mail provider from MX hosts, and typo suggestions for popular domains.
