x402
DNS Propagation Checker is a paid API for AI agents from api.kadec0.xyz, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-13).
Checks DNS propagation status for a domain by querying multiple public resolvers (Google, Cloudflare, Quad9, OpenDNS) and comparing results to detect propagation lag or split-horizon discrepancies.

How this service works
DNS propagation checker. Compares a DNS record across public resolvers (Google, Cloudflare, Quad9, OpenDNS) to spot propagation lag or split-horizon answers.
Output
Returns the DNS record values returned by each public resolver (Google 8.8.8.8, Cloudflare 1.1.1.1, Quad9 9.9.9.9, OpenDNS) for the queried domain and record type, allowing comparison to identify propagation lag or split-horizon answers.
Example use cases
Example prompt
“Can you check if my DNS changes for example.com have propagated across Google, Cloudflare, Quad9, and OpenDNS? I just updated the A record an hour ago and want to see if the resolvers agree.”
Technical details
Endpoint
GEThttps://api.kadec0.xyz/v1/dns-propagationWhen to prefer
Use this endpoint when you need to compare DNS resolution across multiple authoritative public resolvers simultaneously rather than just querying a single resolver. Ideal for diagnosing post-change propagation lag, split-horizon mismatches, or validating that DNS updates are globally consistent.
Side effects
- Invalid domain name returns error or empty result
- Unsupported record type (outside A/AAAA/CNAME/MX/NS/TXT enum) rejected
- Domain parameter missing causes 400-level error
- Resolver timeout causes partial or incomplete comparison results
- Non-existent domain returns NXDOMAIN across all resolvers
