# dns-https-via-dnssb

> dns-https-via-dnssb 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).

Retrieves HTTPS DNS records for a domain using DNS.SB as the resolver via DNS over HTTPS, returning records, TTL, response code, DNSSEC validation status, and answer time.

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-dnssb-2f29dc8c
```

Example prompt: Check what HTTPS DNS records DNS.SB returns for example.com — I want to see the records, TTL, whether DNSSEC was validated, and how fast DNS.SB answered.

## When to prefer this

Use this endpoint when you specifically need to see how DNS.SB resolves HTTPS records for a domain, especially when comparing resolver behavior, detecting propagation lag, identifying split-horizon configurations, or verifying DNSSEC validation status from DNS.SB's perspective. Prefer this over generic DNS tools when resolver-specific answers or answer timing from DNS.SB are important.

## Known failure modes

- Domain does not exist — returns NXDOMAIN response code
- DNS.SB resolver fails to resolve — returns SERVFAIL response code
- No HTTPS records exist for domain — empty record set with NOERROR
- Network timeout contacting DNS.SB — may result in error or delayed response
- DNSSEC validation failure — validation flag set to false with possible SERVFAIL

## How this service works

HTTPS records for a domain as answered by DNS.SB (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 resolved by DNS.SB, including the record data, TTL, response code (NOERROR, NXDOMAIN, or SERVFAIL), a flag indicating whether DNSSEC validation was performed, and the resolver's answer time in milliseconds.
