email_auth_report | Full email-auth report for a domain: SPF (recursive 10-lookup count, void lookups, +all/?all, terms after all), DMARC (policy, pct, alignment, rua authorization), DKIM (keys and RSA key bits at common selectors or your own via selectors=), MX/null MX, MTA-STS policy, TLS-RPT, BIMI, and a Gmail/Yahoo |
spf_lookup_count | Expands a domain's SPF record recursively (include/redirect) like a receiver does and counts DNS-querying terms against the RFC 7208 limit of 10 and void lookups against the limit of 2. Returns per-term lookup costs, problems (permerror causes) and warnings. Deterministic, no AI. Price: $0.001 USDC |
dmarc_check | Finds and validates a domain's DMARC record (falls back to the organizational domain): policy, subdomain policy, pct, alignment modes, rua/ruf, and whether external report domains authorized reports (RFC 7489 7.1). Deterministic, no AI. Price: $0.001 USDC per call via x402 (Base); the first 5 calls |
domain_expiry | Registration data for a domain from the registry's RDAP server (IANA bootstrap): registrar, created/updated/expiry dates, days until expiry with ok/expiring_soon/expired status, EPP status codes, nameservers and DNSSEC. Works for gTLDs and ccTLDs that publish RDAP. Deterministic, no AI. Price: $0.00 |
