# NetIntel DNS Propagation Checker

> NetIntel DNS Propagation Checker is a paid API for AI agents from netintel-production-440c.up.railway.app, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-11).

Queries a domain's DNS record across 10 geographically distributed public resolvers simultaneously and returns per-resolver results, consistency status, propagation percentage, and a readiness grade.

## Facts

- Endpoint: GET https://netintel-production-440c.up.railway.app/dns-propagation/check?utm_source=zero.xyz
- Price: $0.03/call
- Payment: x402

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 netintel-production-440c-up-railway-app-4abba34f
```

Example prompt: Has my DNS change fully propagated? Check the A record for mybrand.com across all public resolvers and tell me the propagation percentage and whether the results are consistent.

## When to prefer this

Use this endpoint when you need to confirm that a DNS change (A, AAAA, MX, TXT, CNAME, or NS record) has propagated to the major public resolvers worldwide. It is the right choice when you want a propagation percentage and a consistency check across 10 named resolvers (Google, Cloudflare, OpenDNS, etc.) in a single call, rather than querying a single resolver or using a generic DNS lookup.

## Known failure modes

- Domain does not exist — resolvers return NXDOMAIN, propagation reported as 0%
- Invalid domain format — returns validation error
- Record type not found — resolvers return empty or NOERROR with no records
- Network timeout to one or more resolvers — affected resolvers marked with failure status
- Unsupported record_type value — returns error or defaults to A record

## How this service works

Query a domain's DNS record across 10 geographically distributed public resolvers simultaneously — returns what each resolver sees, whether results are consistent, propagation percentage, and a readiness score so agents can confirm DNS changes have fully propagated globally.

## Output

Returns a per-resolver breakdown (name, IP, status, records returned, response time, majority match), a boolean consistency flag, the majority DNS value, a list of divergent resolvers, a propagation percentage (0–100), a letter grade (e.g. A), and a numeric readiness score.
