# dns-cname-via-alidns

> dns-cname-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 2026-10-21).

Resolves CNAME records for a domain using AliDNS (223.5.5.5) 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-cname-via-alidns-94a028f8
```

Example prompt: Look up the CNAME records for example.com using AliDNS (223.5.5.5) and tell me the records returned, their TTL, the 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 AliDNS (Alibaba's public resolver at 223.5.5.5) resolves a CNAME record — especially useful for comparing resolution behavior across multiple resolvers, detecting propagation lag to Chinese/Asia-Pacific infrastructure, or investigating whether AliDNS is filtering or returning split-horizon answers differently from Western resolvers.

## Known failure modes

- NXDOMAIN if the domain does not exist or has no CNAME record
- SERVFAIL if AliDNS is unable to resolve the domain
- Network timeout if AliDNS 223.5.5.5 is unreachable
- No records returned if domain has A records but no CNAME

## How this service works

CNAME 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 CNAME record set (alias targets), TTL values, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), a boolean indicating whether the AliDNS resolver performed DNSSEC validation, and the resolver's answer latency in milliseconds.
