How this service works
Call when an agent needs CNAME targets only. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/dns-cname first.
Output
Returns the CNAME target(s) that the given hostname resolves to, i.e. the canonical name the alias points to in DNS.
Example use cases
Verify CDN alias configuration
“Can you check what CNAME target cdn.mycompany.com is pointing to? I need to confirm it's correctly aliased to our CDN provider.”
Debug email deliverability setup
“Look up the CNAME record for mail.acmecorp.com — I'm trying to figure out what it resolves to so I can troubleshoot our email routing.”
Audit third-party service delegation
“What does the CNAME for tracking.mybrand.io point to? I want to see which third-party service we've delegated that subdomain to.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-cname?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need programmatically look up CNAME targets for a specific hostname and want a simple paid API call rather than running your own DNS resolver. Prefer the free sandbox endpoint POST /v1/sandbox/dns-cname first if available. Choose this over generic DNS APIs when integrating into an agent workflow that already handles x402 micropayments.
Side effects
- Hostname has no CNAME record — returns empty or error indicating record not found
- Invalid or malformed hostname input — returns validation error
- Hostname does not exist in DNS — NXDOMAIN or equivalent error
- Network or resolver timeout — service unavailable error
- Payment not received or insufficient — HTTP 402 error
