# dns-srv-via-cleanbrowsing

> dns-srv-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).

Fetches SRV DNS records for a domain via CleanBrowsing's security-filtering DNS-over-HTTPS resolver, returning records, TTL, response code, DNSSEC validation status, and answer latency.

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-srv-via-cleanbrowsing-3b4f59a6
```

Example prompt: What SRV 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

Use this endpoint when you specifically need to see how CleanBrowsing's security-filtering DNS resolver answers SRV record queries — for example to detect whether CleanBrowsing is blocking or filtering a domain's service records, to compare resolver answers for split-horizon or propagation analysis, or to verify DNSSEC validation behavior at CleanBrowsing specifically. Prefer this over generic SRV lookup tools when resolver identity and security filtering matter.

## Known failure modes

- Domain does not exist — returns NXDOMAIN response code
- CleanBrowsing filters or blocks the domain — may return SERVFAIL or empty answer section
- Domain has no SRV records — returns NOERROR with empty answer
- Resolver timeout or upstream failure — returns SERVFAIL
- Invalid or malformed domain input — may return error or SERVFAIL
- DNSSEC validation failure — resolver may return SERVFAIL with DNSSEC flag

## How this service works

SRV 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 SRV record set for the queried domain as seen by CleanBrowsing's security-filtering DoH resolver, including: the SRV record values (priority, weight, port, target), TTL, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), whether the resolver performed DNSSEC validation, and the resolver's answer latency in milliseconds.
