# dns-naptr-via-adguard

> dns-naptr-via-adguard is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Fetches NAPTR DNS records for a domain using AdGuard DNS over HTTPS, returning records, TTL, response code, DNSSEC validation status, and resolver answer time.

## 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-naptr-via-adguard-c44cf5e5
```

Example prompt: Can you look up the NAPTR records for example.com using AdGuard DNS and tell me the response code, TTL, and whether DNSSEC was validated?

## When to prefer this

Choose this endpoint when you specifically need NAPTR records as resolved by AdGuard DNS, especially when comparing resolver behavior across multiple providers (e.g., AdGuard vs. Google vs. Cloudflare) to detect DNS filtering, split-horizon configurations, or propagation delays. It is particularly useful for VoIP/SIP troubleshooting where NAPTR records govern routing, and when DNSSEC validation status per-resolver matters.

## Known failure modes

- Domain does not exist — returns NXDOMAIN response code with empty records
- No NAPTR records configured for domain — returns NOERROR with empty record set
- AdGuard DNS filters the domain — may return NXDOMAIN or empty records even if records exist elsewhere
- Resolver unavailable — returns SERVFAIL response code
- Missing domain query parameter — returns 400 or error response
- Network timeout — no response returned within expected window

## How this service works

NAPTR records for a domain as answered by AdGuard DNS (DNS over HTTPS): the records, TTL, response code (NOERROR/NXDOMAIN/SERVFAIL), whether the resolver validated DNSSEC, and the resolver's answer time. Compare resolvers to spot propagation lag, filtering or split-horizon answers. $0.01 per lookup.

## Output

Returns the NAPTR DNS records for the queried domain as seen by AdGuard DNS, including the record data, TTL, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), a flag indicating whether DNSSEC was validated by the resolver, and the resolver's answer time in milliseconds.
