How this service works
Call when an agent needs NAPTR records at the exact hostname. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/dns-naptr first.
Output
Returns the NAPTR DNS records associated with the queried hostname, including fields such as order, preference, flags, service type, regular expression, and replacement hostname for each record found.
Example use cases
SIP telephony service discovery
“What NAPTR records are configured for voice.mycompany.com? I need to figure out what SIP services and protocols are advertised there.”
URI resolution scheme lookup
“Can you fetch the NAPTR DNS records for enum.example.net so I can see how calls to that domain get routed?”
DNS misconfiguration debugging
“I'm troubleshooting why our NAPTR-based service discovery isn't working — can you pull the NAPTR records for services.acmecorp.io and show me what's there?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-naptr?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need programmatic access to NAPTR DNS records for a specific hostname, particularly for SIP/telephony service discovery, ENUM lookups, or URI resolution schemes. Prefer this over manual DNS tooling when operating in an agentic workflow that requires structured, machine-readable NAPTR data with predictable pricing.
Side effects
- Hostname does not exist (NXDOMAIN) — empty or error response
- No NAPTR records found for a valid hostname
- Invalid hostname format (exceeds 253 chars or malformed) — validation error
- DNS timeout or upstream resolver failure
- Private or reserved hostnames may be rejected
