How this service works
Resolve DNS records of any common type over DoH, returning answers with TTLs and the DNSSEC-authenticated flag.
Output
A structured list of DNS answer records for the queried hostname and type, each with the record data (e.g. IP address, mail server, text value), its TTL in seconds, and a boolean flag indicating whether the response was DNSSEC-authenticated.
Example use cases
SPF/DKIM email deliverability check
“Fetch the TXT records for mailchimp.com so I can see its SPF and DKIM entries and check if they're DNSSEC-authenticated.”
Nameserver discovery for a domain
“What are the NS records for github.com? I want to know which nameservers are authoritative and what TTLs they have.”
Reverse DNS PTR lookup
“Do a PTR record lookup for 8.8.8.8 so I can see what hostname Google's public DNS server resolves to.”

Endpoint
GEThttps://fittings.sh/v1/net/dns-lookup?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative, DNSSEC-aware DNS resolution over HTTPS without running your own resolver — especially useful for agents verifying email deliverability (SPF/DKIM/DMARC TXT records), auditing domain security posture (CAA, DNSSEC), or programmatically discovering infrastructure (A, AAAA, NS, SRV records) in a serverless or restricted environment.
Side effects
- Hostname does not exist (NXDOMAIN) — returns an empty or error response
- Unsupported or misspelled record type — validation error
- DNS resolution timeout or upstream DoH server unavailable
- DNSSEC validation failure for a domain with broken DNSSEC configuration
- Rate limiting or payment failure for the x402 micropayment
