How this service works
DNS A record lookup: resolve a domain name to its IPv4 addresses with TTL, record count, DNSSEC validation flag and response code, via DNS-over-HTTPS. Fast, no API key. $0.01 per lookup.
Output
Returns the resolved IPv4 address(es) for the queried domain, along with TTL (time-to-live in seconds), the total number of A records returned, a DNSSEC validation flag indicating whether the response is DNSSEC-validated, and the DNS response code (e.g. NOERROR, NXDOMAIN, SERVFAIL).
Example use cases
Verify domain IP before deployment
“What IPv4 addresses is api.mycompany.com currently resolving to? I want to check the A records and TTL before we push our DNS change live.”
Security audit of third-party domain
“Look up the A records for payments.vendor.com — I need the IPv4 addresses, whether DNSSEC is valid, and what the DNS response code is.”
Monitor DNS propagation after migration
“Can you check the DNS A records for shop.mybrand.com and tell me the current IP addresses, record count, and TTL? I just updated my nameservers and want to see if it's propagated.”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/dns/aWhen to prefer
Use this endpoint when you need fast, keyless DNS A record resolution with structured metadata (TTL, record count, DNSSEC flag, response code) and are happy paying $0.01 per lookup. Prefer it over general DNS lookup endpoints when you specifically need IPv4 A records with DNSSEC validation status. Its sibling dns-lookup endpoint covers multiple record types (A, MX, TXT) in one call if you need broader DNS data.
Side effects
- NXDOMAIN response if domain does not exist
- SERVFAIL if upstream DNS resolver is unreachable or the domain has misconfigured nameservers
- Empty record set if the domain has no A records (e.g. only AAAA or CNAME)
- Timeout if the DNS-over-HTTPS provider is slow to respond
- Payment failure if the $0.01 USDC x402 payment is not accepted
