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 structured DNS record data for the queried domain and record type, including record values such as IP addresses (A/AAAA), mail server hostnames and priorities (MX), name server hostnames (NS), text strings (TXT), canonical name targets (CNAME), or authoritative zone information (SOA), sourced live from Cloudflare's DNS-over-HTTPS resolver.
Example use cases
Email deliverability pre-check
“Before I send a bulk email campaign to addresses at acme.com, can you check if that domain has valid MX records set up?”
Domain infrastructure discovery
“I need to find all the name servers and SOA record for stripe.com to understand who controls their DNS.”
SPF record verification
“Can you pull the TXT records for shopify.com so I can see if they have an SPF record configured?”
Technical details
Endpoint
GEThttps://agenttools-hub.vercel.app/api/v1/live/dns-lookup?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, authoritative DNS resolution backed by Cloudflare's reliable DoH infrastructure rather than cached or system-level DNS. Ideal for email deliverability pre-checks (MX lookups), domain ownership verification (TXT/SPF/DKIM), infrastructure discovery (NS/SOA), and resolving hostnames to IPs (A/AAAA). Prefer this over generic DNS tools when you need a specific record type from a trusted, low-latency resolver with structured JSON output.
Side effects
- Domain does not exist (NXDOMAIN) — returns empty or error response
- Requested record type not found for the domain — returns empty records
- Invalid domain format — schema validation error
- Network or Cloudflare resolver timeout — upstream latency error
- Rate limiting or payment failure — 402 or 429 response
