# dns-https-via-nextdns

> dns-https-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 2026-10-01).

Resolves HTTPS DNS records for a domain using NextDNS via DNS over HTTPS, returning records, TTL, response code, DNSSEC validation status, and answer latency.

## 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-https-via-nextdns-14810355
```

Example prompt: What HTTPS DNS records does NextDNS return for example.com — include the TTL, response code, whether DNSSEC was validated, and how long NextDNS took to answer?

## When to prefer this

Choose this endpoint when you specifically need to see how NextDNS resolves HTTPS records for a domain — particularly useful for comparing resolver behavior, detecting DNS-level filtering or blocking by NextDNS, checking DNSSEC validation, or diagnosing propagation lag relative to other resolvers like Cloudflare, Google, or AliDNS. Prefer sibling endpoints for other record types (SRV, TXT, DS, DNSKEY) or for querying other resolvers.

## Known failure modes

- Domain does not exist — NextDNS returns NXDOMAIN response code
- Resolver error — SERVFAIL response code returned if NextDNS cannot resolve the query
- No HTTPS records for domain — NOERROR with empty answer section
- Network or upstream timeout — resolver answer time may be very high or endpoint may error
- Invalid domain input — malformed domain name may cause a 400 or empty response

## How this service works

HTTPS 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 HTTPS DNS records for the queried domain as answered by NextDNS, including the full record set, TTL, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), a boolean indicating whether the resolver performed DNSSEC validation, and the resolver's answer latency in milliseconds.
