# dns-cname-via-google

> dns-cname-via-google 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 CNAME DNS records for a domain using Google's 8.8.8.8 resolver via DNS over HTTPS, returning records, TTL, response code, DNSSEC validation status, and answer time.

## Facts

- Endpoint: GET https://dns.intel.rallylive.ca/dns/cname/via/google?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-01
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/dns-cname-via-google-f62267c5
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_mwrxLGnRgYoRhfjEBkJxN

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-google-f62267c5
```

Example prompt: What CNAME records does Google's 8.8.8.8 DNS resolver return for shop.example.com — include the TTL, response code, and whether DNSSEC was validated?

## When to prefer this

Choose this endpoint when you specifically need to see how Google's 8.8.8.8 resolver (the world's most widely used public DNS) answers a CNAME query — useful for propagation checks, detecting resolver-specific filtering, comparing against other resolvers (e.g. Cloudflare, AdGuard) for split-horizon analysis, or auditing DNSSEC validation status. Prefer sibling endpoints (dns-cname-via-dnssb, etc.) when you need a multi-resolver comparison baseline.

## Known failure modes

- Domain does not exist — response code NXDOMAIN returned
- Domain exists but has no CNAME record — empty record set
- Resolver cannot reach authoritative server — SERVFAIL returned
- Malformed domain input causing query failure
- Network timeout reaching Google DoH endpoint

## How this service works

CNAME records for a domain as answered by Google 8.8.8.8 (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 for the queried domain as seen by Google 8.8.8.8, including the canonical name targets, TTL value, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), a boolean indicating whether DNSSEC was validated by the resolver, and the resolver's answer latency in milliseconds.
