# netintel DNS Propagation Check

> netintel DNS Propagation Check is a paid API for AI agents from netintel.x.c00l.site, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Checks DNS propagation for a given hostname and record type across multiple global resolvers, returning per-resolver answers and consistency analysis.

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-dns-propagation-check-ad728f28 -d '<json body>'
```

Example prompt: Check whether my A record for example.com has fully propagated across global DNS resolvers — I want to see which resolvers agree and whether they're all returning the same answer.

## When to prefer this

Choose this endpoint when you need to verify whether DNS changes (A, MX, NS, CNAME, TXT, etc.) have propagated across multiple global resolvers simultaneously and want a consistency/agreement analysis. Prefer it over a single-resolver DNS lookup when you specifically need multi-resolver comparison, latency data per resolver, or a propagation health check after a DNS change. It is pay-per-call with no account required, making it ideal for ad-hoc or automated checks without API key management overhead.

## Known failure modes

- Invalid or non-existent domain name returns resolver errors or empty answers
- Unsupported DNS record type may return empty or error responses
- Payment failure (x402) results in 402 response before query is executed
- Network timeouts from specific resolvers may mark individual resolvers as not OK
- Very recently changed DNS records may show majority disagreement, not indicating an error but a propagation-in-progress state

## How this service works

Paid-per-call network intelligence API: DNS with DNSSEC, email deliverability, TLS certificate inspection, IP/ASN lookup and DNS propagation. From $0.002 a call over x402. No account, no API key.

## Output

Returns a JSON object with the queried domain name, record type, and an array of per-resolver results (resolver ID, name, latency in ms, whether it responded successfully, DNS answers, and whether it agrees with the majority). Also includes a top-level consistency flag, agreement ratio (0–1), and count of distinct answer sets observed across resolvers.
