# dns-srv-via-alidns

> dns-srv-via-alidns is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-01).

Looks up SRV DNS records for a domain using AliDNS (223.5.5.5) via DNS over HTTPS, 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-alidns-8f4e0c99
```

Example prompt: Can you look up the SRV records for _sip._tcp.example.com using AliDNS and tell me what records it returns, the TTL, whether DNSSEC is validated, and how fast it answered?

## When to prefer this

Choose this endpoint when you specifically need to see how AliDNS (a major Chinese public resolver at 223.5.5.5) answers SRV queries — particularly useful for diagnosing DNS propagation delays, detecting resolver-level filtering, or investigating split-horizon DNS differences between regional resolvers. Prefer this over generic DNS tools when you need resolver-specific comparison data including DNSSEC validation status and answer latency from AliDNS.

## Known failure modes

- NXDOMAIN returned if the domain has no SRV records or does not exist
- SERVFAIL if AliDNS encounters an upstream resolution error
- Network timeout if AliDNS is unreachable
- Empty records array if the domain exists but has no SRV entries
- Payment failure if USDC balance is insufficient for the $0.01 fee

## How this service works

SRV records for a domain as answered by AliDNS 223.5.5.5 (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 AliDNS (223.5.5.5), including the record values (priority, weight, port, target), TTL, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), whether the resolver validated DNSSEC, and the resolver's answer time in milliseconds.
