How this service works
Query live DNS records (A, AAAA, MX, TXT, NS, CNAME, SOA) through Cloudflare's DNS-over-HTTPS resolver. Domain validation, email deliverability pre-checks and infrastructure discovery. Use this when an agent needs to real DNS records via Cloudflare DNS-over-HTTPS.
Output
Returns the live DNS response for the requested record type, including the DNS answer records with their values (e.g. IP addresses for A records, hostnames for MX/CNAME/NS, strings for TXT, serial/refresh info for SOA), sourced directly from Cloudflare's DNS-over-HTTPS resolver.
Example use cases
Email deliverability pre-check
“Before I send a bulk email campaign to addresses at acmecorp.com, can you check whether that domain has valid MX records set up so I know emails won't bounce?”
Verify SPF or DKIM TXT record
“Can you fetch the TXT records for sendgrid.net so I can confirm their SPF record is published correctly in DNS?”
Discover domain's IP addresses
“What IP addresses does shopify.com resolve to? Fetch the A records so I can see their current DNS configuration.”

Endpoint
GEThttps://agentstoolshub.com/api/v1/live/dns-lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs real-time, authoritative DNS record resolution backed by Cloudflare's globally distributed DoH infrastructure, especially for email deliverability checks (MX), domain ownership verification (TXT), IP resolution (A/AAAA), or infrastructure discovery (NS, CNAME, SOA). Prefer this over cached or system-resolver lookups when freshness and reliability matter.
Side effects
- Domain does not exist — NXDOMAIN response returned
- Requested record type not found for domain — empty answer section
- Invalid domain format supplied — query rejected
- DNS resolution timeout from Cloudflare upstream
- Unsupported record type requested (only A, AAAA, MX, TXT, NS, CNAME, SOA accepted)
- Payment not attached or insufficient USDC — 402 response
