DNS Propagation Check
x402
DNS Propagation Check is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).
Resolves a domain's A and MX records across Cloudflare (1.1.1.1), Google (8.8.8.8), and Quad9 resolvers to verify DNS propagation consistency after a record update or migration.

How this service works
DNS propagation check: resolves a domain's A and MX records through three independent public resolvers (Cloudflare 1.1.1.1, Google 8.8.8.8, Quad9) and reports whether all agree. Verify a DNS change has propagated after a migration or record update. $0.01 per domain.
Output
Returns the A and MX record values returned by each of the three resolvers (Cloudflare 1.1.1.1, Google 8.8.8.8, Quad9), plus a boolean or status indicator of whether all three resolvers agree, helping you confirm whether a DNS change has fully propagated.
Example use cases
Post-migration DNS verification
“I just migrated mybusiness.com to a new server and updated the A record. Can you check if the DNS change has propagated across Cloudflare, Google, and Quad9 so I know it's safe to cut over?”
Email setup propagation check
“I added MX records for mycompany.org yesterday for our new email provider. Can you verify the MX records have propagated consistently across all three major public resolvers?”
Diagnosing inconsistent DNS resolution
“Some users are hitting the old version of devteam.io and some are hitting the new one. Can you check if the A records for devteam.io are consistent across Cloudflare, Google, and Quad9 to see if it's a propagation issue?”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/dns/propagationWhen to prefer
Choose this endpoint when you need a quick, multi-resolver DNS consistency check specifically comparing Cloudflare, Google, and Quad9 simultaneously for A and MX records. It's ideal post-migration or post-record-update verification workflows where you need to confirm global propagation without setting up your own resolver infrastructure.
Side effects
- Invalid or non-existent domain name returns an error or empty record set
- Resolvers may return NXDOMAIN if the domain doesn't exist
- Timeout if a resolver is temporarily unreachable
- Domain with no MX records will show empty MX results rather than failure
- Propagation may appear inconsistent during the propagation window — this is expected and not a bug
