	Description		Read-only	Idempotent	Open world
`domain_age`PAID ($0.005). Not for registries without RDAP, e.g. .za/.co.za, .me, .de, .io, .eu: refused free (422). Use when you need to know which registrar holds a domain, how old it is, and whether it is a risky newly-registered domain. $0.005. From the registry's RDAP: registrar name and IANA ID (no registrant or contact data), created, expires, last changed, status flags, DNSSEC delegation, nameservers; fail under 30 days old or expired, warn under 180 days, expiring within 30 days or on hold. A registry without RDAP is refused free. MCP: pass api_key (an Afriref key, card credit at https://afriref.dev/pricing); per-call x402/MPP payment is HTTP only, so without a key the result is an api_key_required error naming the HTTP endpoint.

`domain_check`PAID ($0.01). Use when mail lands in spam, before an email campaign, for vendor due diligence or to confirm a Microsoft 365 tenant: graded SPF, DKIM, DMARC, MX, MTA-STS, DNSSEC, CAA, TLS and domain age, plus BIMI and blocklist info, each with the exact fix record. Non-intrusive. $0.01 per domain. Returns a 0-100 score and, per check (spf, dkim, dmarc, mx, tls = website certificate, m365, registration, mta_sts, tls_rpt, dnssec, caa, bimi, dnsbl = UCEPROTECT blocklist), a pass/warn/fail/info grade, the finding and the exact record or step that fixes it. Info checks do not move the score. Invalid, nonexistent or private-only domains are refused free.
