# DNS Propagation Check

> 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.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability dns-propagation-check-cad7dcaa
```

Example prompt: Can you check if the DNS changes for example.com have propagated — specifically whether Cloudflare, Google, and Quad9 all agree on the A and MX records?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
