How this service works
Resolve DNS records for a hostname — A, AAAA, CNAME, MX, TXT, NS, SOA, CAA or SRV. NXDOMAIN or an absent record type returns an empty record set.
Output
Returns the DNS record set matching the requested hostname and record type. Each record includes the relevant data fields for that type (e.g. IP address for A/AAAA, hostname and priority for MX, text value for TXT). If the domain does not exist (NXDOMAIN) or the requested record type is absent, an empty record set is returned.
Example use cases
Verify SPF record for email deliverability
“Can you pull the TXT records for sendgrid.net? I want to check what their SPF record looks like before I set up my own.”
Check IPv6 support for a domain
“Does stripe.com have an AAAA record? I need to know if they support IPv6 before I configure my firewall rules.”
Identify certificate authority restrictions
“Look up the CAA records for github.com — I want to see which certificate authorities are allowed to issue TLS certs for that domain.”
Technical details
Endpoint
POSThttps://dns.openverbs.com/v1/resolveWhen to prefer
Use this endpoint when an AI agent needs programmatic, paid DNS resolution supporting all major record types (A, AAAA, CNAME, MX, TXT, NS, SOA, CAA, SRV) in a single consistent API with x402 micropayment access. Prefer it over scraping DNS tools or system-level resolvers when you need a reliable, structured JSON response for any record type without managing resolver infrastructure. The companion PTR/reverse-lookup endpoint on the same provider covers reverse DNS needs.
Side effects
- NXDOMAIN: domain does not exist — returns empty record set
- No records of requested type exist — returns empty record set
- Invalid hostname format (exceeds 253 chars or malformed) — likely validation error
- Unsupported record type supplied — schema enum violation
- Upstream DNS resolver timeout — may return error or empty result
