How this service works
Call when an agent needs NS hostnames for the public name. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/dns-ns first.
Output
A list of NS (name server) hostnames that are authoritative for the queried domain, as returned by DNS resolution. Typically includes two or more name server FQDNs (e.g. ns1.example.com, ns2.example.com).
Example use cases
Verify domain DNS delegation
“Can you look up the name servers for shopify.com so I can confirm which DNS provider they're using?”
Audit domain hosting infrastructure
“I need to know the authoritative NS records for cloudflare.com — pull them for me so I can document their DNS setup.”
Debug DNS misconfiguration
“Something looks off with the DNS for my client's site mybusiness.example.com — can you fetch its NS hostnames so we can check if the delegation is correct?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-ns?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically retrieve authoritative NS records for a public domain name as part of DNS auditing, infrastructure analysis, domain verification, or DNS delegation checks. Prefer the free sandbox endpoint (/v1/sandbox/dns-ns) for testing or non-production lookups to avoid the $0.001 USDC charge.
Side effects
- Domain does not exist or has no NS records — returns empty or error response
- Malformed hostname input exceeding 253 characters or empty string — rejected by schema validation
- Private or internal hostname not publicly resolvable — lookup fails
- Temporary DNS resolution failure or upstream timeout — may return error
