How this service works
DNS lookup over DoH. Common record types (A, AAAA, MX, TXT, NS, CAA, ...) as clean JSON.
Output
A clean JSON object containing the resolved DNS records for the queried domain and record type, including record values (e.g. IP addresses, hostnames, priority values, TTLs) structured by record type.
Example use cases
Email deliverability troubleshooting
“Look up the MX and TXT records for example.com — I need to check if their SPF and DKIM are set up correctly.”
DNSSEC validation check
“Fetch the DS and DNSKEY records for cloudflare.com so I can verify their DNSSEC chain of trust.”
IPv6 connectivity check
“Resolve the AAAA record for api.stripe.com — I want to confirm they have an IPv6 address before I update my firewall rules.”
Technical details
Endpoint
GEThttps://toolvend.dev/dnsWhen to prefer
Use this endpoint when you need a fast, structured JSON response for DNS lookups without parsing raw DNS wire format or dealing with plain-text WHOIS/dig output. Prefer it over RDAP (which gives registrar/registration data) when you need live DNS resolution. Ideal for agents that need to programmatically check mail servers, IP addresses, SPF/DKIM records, DNSSEC chains, or nameservers as part of an automated workflow.
Side effects
- Domain does not exist (NXDOMAIN) — returns empty or error response
- Invalid domain name format — rejected by schema validation (minLength/maxLength)
- Unsupported record type — only the enumerated types (A, AAAA, CNAME, MX, NS, TXT, SOA, SRV, CAA, DS, DNSKEY, TLSA, HTTPS) are accepted
- DNS resolution timeout — upstream resolver may be slow or unreachable
- Payment failure — x402 payment of $0.005 USDC not processed correctly
