# dns-srv-via-cloudflare

> dns-srv-via-cloudflare 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 SRV DNS records for a domain using Cloudflare 1.1.1.1 (DNS over HTTPS) and returns records, TTL, response code, DNSSEC validation status, and resolver answer time.

## Facts

- Price: $0.01/call
- Payment: x402
- Status: unknown

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-cloudflare-09ba5255
```

Example prompt: Look up the SRV records for _sip._tcp.example.com as answered by Cloudflare 1.1.1.1 and tell me the records, TTL, response code, whether DNSSEC was validated, and how long Cloudflare took to answer.

## When to prefer this

Choose this endpoint when you specifically need SRV records as seen by Cloudflare 1.1.1.1 — for example, to check service discovery records (SIP, XMPP, Minecraft, etc.), verify DNSSEC validation status from Cloudflare's perspective, measure Cloudflare's resolver latency, or compare answers across multiple resolvers to detect propagation lag, filtering, or split-horizon DNS.

## Known failure modes

- NXDOMAIN if the domain or SRV record does not exist
- SERVFAIL if Cloudflare cannot resolve the domain
- Empty record set if no SRV records are configured for the domain
- Network timeout if the DoH endpoint is unreachable
- Payment failure if USDC balance is insufficient for the $0.01 per-call fee

## How this service works

SRV records for a domain as answered by Cloudflare 1.1.1.1 (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 DNS records for the queried domain as answered by Cloudflare 1.1.1.1 via DNS over HTTPS, including the record data (priority, weight, port, target), TTL, response code (NOERROR, NXDOMAIN, or SERVFAIL), whether DNSSEC was validated by the resolver, and the resolver's answer time in milliseconds.
