# dns-naptr-via-alidns

> dns-naptr-via-alidns is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-21).

Fetches NAPTR DNS records for a domain via AliDNS (223.5.5.5) 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-alidns-02ddc5b1
```

Example prompt: What NAPTR records does AliDNS (223.5.5.5) return for example.com — including the TTL, response code, and whether DNSSEC was validated?

## When to prefer this

Choose this endpoint when you specifically need to see how AliDNS (223.5.5.5), Alibaba's public resolver, answers NAPTR queries — useful for diagnosing propagation lag in Asia-Pacific regions, detecting resolver-level filtering, or comparing split-horizon behavior against other resolvers like Google, Cloudflare, or NextDNS. Use sibling endpoints for other resolvers or other DNS record types.

## Known failure modes

- Domain does not exist — NXDOMAIN response code returned
- AliDNS resolver fails to answer — SERVFAIL response code returned
- No NAPTR records exist for the domain — empty records array with NOERROR
- Network timeout reaching AliDNS — request error or slow response
- Invalid domain name format — request rejected or malformed query

## How this service works

NAPTR records for a domain as answered by AliDNS 223.5.5.5 (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 NAPTR DNS records as seen by AliDNS (223.5.5.5), including the record values, TTL, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), whether the resolver performed DNSSEC validation, and the resolver's answer latency in milliseconds.
