How this service works
Look up DNS records for any hostname: query A, AAAA, MX, TXT, CNAME, NS, SOA, CAA, SRV and PTR records with TTLs over DNS-over-HTTPS. Check mail configuration (MX), SPF/DKIM/DMARC TXT records, nameservers and IP addresses. Fast, reliable DNS resolver and record lookup for domain and infrastructure verification.
Output
Returns a list of DNS records matching the requested type for the given hostname, including record values and TTL (time-to-live) in seconds. For example, an MX lookup returns priority and mail server hostnames; a TXT lookup returns raw text strings useful for SPF/DKIM/DMARC verification.
Example use cases
Example prompt
“Can you look up the MX records for example.com so I can verify its mail server configuration?”
Technical details
Endpoint
GEThttps://api.aventtech.com/lookup/dns?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to programmatically resolve or verify DNS records for any hostname — especially for email deliverability checks (MX, SPF/TXT, DKIM), infrastructure validation (A/AAAA/CNAME/NS), certificate authority authorization (CAA), or reverse DNS (PTR). Prefer over general HTTP-based web scraping when the goal is authoritative DNS data with TTLs. Complements the sibling email deliverability and domain RDAP endpoints on the same platform.
Side effects
- Hostname not found — NXDOMAIN response when the domain does not exist
- Invalid record type specified — returns error if the type parameter is not one of the supported values
- Network or resolver timeout — DNS-over-HTTPS upstream may be temporarily unavailable
- No records of requested type — domain exists but has no records of that type (empty answer)
- Malformed hostname input — error if the name parameter is not a valid DNS name
