How this service works
Call when an agent needs public DNS A, AAAA, MX, TXT, and CNAME records for a hostname (private targets blocked). Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/dns-lookup first.
Output
Returns the requested DNS record types for the given hostname, including record values such as IP addresses for A/AAAA records, mail server hostnames and priorities for MX records, arbitrary text values for TXT records, and canonical name targets for CNAME records. Private/internal IP targets are blocked for security.
Example use cases
Email server discovery for a domain
“What MX records does stripe.com have? I need to know which mail servers handle their email.”
IPv4 and IPv6 address resolution
“Can you get both the A and AAAA DNS records for cloudflare.com so I can see its IPv4 and IPv6 addresses?”
Domain ownership TXT record check
“Look up the TXT records for shopify.com — I want to see their SPF and domain verification entries.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to programmatically resolve one or more standard DNS record types for a public hostname, especially when you need multiple record types in a single call (up to 5). It is SSRF-safe (private targets blocked) and priced at $0.003 USDC per call, making it suitable for lightweight DNS enrichment tasks. Prefer the free sandbox endpoint (/v1/sandbox/dns-lookup) for testing before incurring charges.
Side effects
- Private or internal hostnames are blocked and will be rejected
- Invalid or malformed hostnames return an error
- Requesting zero or more than 5 record types at once is rejected
- Non-existent domains may return empty results or NXDOMAIN
- Network or upstream resolver errors may cause transient failures
