# dns-txt-via-cleanbrowsing

> dns-txt-via-cleanbrowsing 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).

Retrieves DNS TXT records for a domain as answered by the CleanBrowsing security-filter 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-txt-via-cleanbrowsing-0fcc1a81
```

Example prompt: What TXT records does CleanBrowsing's security-filter DNS return for example.com — include the TTL, response code, whether DNSSEC was validated, and how fast it answered?

## When to prefer this

Choose this endpoint when you specifically need to see what the CleanBrowsing security-filter DNS resolver answers for TXT records — particularly useful when comparing resolver outputs to detect filtering, propagation lag, or split-horizon behavior, or when validating SPF/DKIM/DMARC records from a security-focused resolver's perspective. Prefer it over generic DNS lookup tools when DNSSEC validation status and per-resolver answer timing matter.

## Known failure modes

- Domain does not exist — response code NXDOMAIN returned with no records
- Domain exists but has no TXT records — NOERROR with empty record set
- CleanBrowsing filters or blocks the domain — may return NXDOMAIN or modified response instead of true answer
- DNS resolution failure at CleanBrowsing — SERVFAIL response code
- Invalid or malformed domain name input — request rejected
- Network timeout reaching CleanBrowsing resolver — service error

## How this service works

TXT records for a domain as answered by CleanBrowsing (security filter) (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

A structured response containing the TXT record values for the queried domain, their TTL, the DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), a boolean indicating whether CleanBrowsing validated DNSSEC, and the resolver's answer latency in milliseconds.
