Use before onboarding a domain to outbound email or as a deliverability pre-flight for a new sending domain. POST JSON {"domains":["example.com", ...]} with a $0.02 USDC x402 payment on Base. Note: DKIM selectors are not discoverable via DNS; a null DKIM result means not found with common selectors, not that the domain does not sign mail.
