# dns-ds-via-cleanbrowsing

> dns-ds-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).

Looks up DS (Delegation Signer) DNS records for a domain as answered by the CleanBrowsing security-filtering DNS resolver via DNS over HTTPS, returning records, TTL, response code, DNSSEC validation status, and resolver answer time.

## Facts

- Price: $0.01/call
- Payment: x402

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-ds-via-cleanbrowsing-dc812b7f
```

Example prompt: What DS records does CleanBrowsing 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 need to see how CleanBrowsing's security-filtering resolver answers DS record queries — particularly to detect filtering/blocking behavior, check DNSSEC validation status from a security-focused resolver, or compare propagation of DS records across resolvers. Prefer this over generic DNS tools when the security-filter perspective or resolver-to-resolver comparison is the goal.

## Known failure modes

- Domain not found (NXDOMAIN) — CleanBrowsing may be filtering the domain or it genuinely does not exist
- SERVFAIL — resolver encountered an upstream error or DNSSEC validation failure
- No DS records returned (empty answer) — domain exists but has no DS records published
- Network timeout reaching CleanBrowsing DoH endpoint — resolver temporarily unavailable
- Malformed domain input — query fails if the domain string is not a valid FQDN

## How this service works

DS 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

Returns the DS records (if any) for the queried domain as answered by CleanBrowsing's security-filtering DoH resolver, 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.
