# dns-aaaa-via-nextdns

> dns-aaaa-via-nextdns 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).

Queries AAAA (IPv6) DNS records for a domain via NextDNS over HTTPS, returning records, TTL, response code, DNSSEC validation status, and resolver answer time.

## Facts

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-aaaa-via-nextdns-48e1698c
```

Example prompt: What AAAA records does NextDNS return for example.com — include the TTL, response code, whether DNSSEC was validated, and how fast the resolver answered?

## When to prefer this

Choose this endpoint when you specifically want to see how NextDNS resolves IPv6 (AAAA) records for a domain — especially to detect DNS filtering, blocking, or split-horizon behavior applied by NextDNS, to verify DNSSEC validation, or to compare propagation lag against other resolvers like Cloudflare, Google, or AliDNS. Prefer sibling endpoints for other record types (A, TXT, SRV) or other resolvers.

## Known failure modes

- Domain does not exist — returns NXDOMAIN response code with no records
- Resolver error — returns SERVFAIL if NextDNS cannot answer
- Domain has no AAAA records — returns NOERROR with empty record set
- Network timeout reaching NextDNS — may return an error or no response
- Invalid domain name input — may cause a 400 bad request or empty response

## How this service works

AAAA records for a domain as answered by NextDNS (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 AAAA (IPv6) records for the queried domain as answered by NextDNS, along with the TTL, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), a flag indicating whether the resolver performed DNSSEC validation, and the resolver's answer latency in milliseconds.
