How this service works
Call when an agent needs SOA as ns, hostmaster, serial, refresh, retry, expire, minimum. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/dns-soa first.
Output
Returns the full SOA record for the queried hostname, including: primary nameserver (ns), hostmaster email address, zone serial number, refresh interval (seconds), retry interval (seconds), expire interval (seconds), and minimum TTL (seconds).
Example use cases
Domain zone health check
“What are the SOA record details for example.com? I need the nameserver, hostmaster, serial number, and all the timing values like refresh, retry, and expire.”
DNS propagation debugging
“Can you fetch the SOA serial number for mybusiness.io so I can check whether DNS changes have propagated yet?”
Hostmaster contact discovery
“I need to find the administrative contact email (hostmaster) for the domain openai.com — can you pull the SOA record and give me that field?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-soa?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to programmatically retrieve SOA DNS record fields for a domain, particularly for infrastructure checks, DNS propagation verification, or identifying the authoritative nameserver and zone administrator. Prefer the free sandbox endpoint (/v1/sandbox/dns-soa) first for testing; use this paid endpoint for production or when the sandbox is unavailable.
Side effects
- Hostname does not exist or has no SOA record — returns an error or empty result
- Malformed hostname input (e.g. exceeds 253 characters) — schema validation error
- DNS timeout or upstream resolver failure — transient error
- Payment not provided or insufficient — 402 Payment Required response
