How this service works
Pay-per-result domain qualification, DNS security audits, and website intelligence over x402.
Output
A JSON object containing the count of requested domains, unique domains, successful lookups, and failed lookups, along with a results array with per-domain intelligence including DNS security posture, qualification signals, and website presence data for each domain submitted.
Example use cases
Lead list domain qualification
“I have a list of 50 prospect domains from our CRM export — acmecorp.com, bestwidgets.io, and 48 others. Can you batch-classify them all and flag which ones are active legitimate businesses vs parked or suspicious domains so I can prioritize my outreach?”
Cold email DNS security pre-screening
“Before we send our next email campaign, can you audit the DNS security setup for these domains — clientone.com and clienttwo.net — and tell me if they have SPF, DKIM, and DMARC configured so we know our emails won't bounce or get flagged?”
Vendor domain vetting
“We're onboarding two new vendors at domains supplierA.com and supplierB.co — can you run a domain intelligence check on both and tell me if they look like real established businesses with a proper web presence and clean DNS setup?”
Technical details
Endpoint
POSThttps://api.servocenter.com/api/v1/domain/batch-classifyWhen to prefer
Choose this endpoint when you need to evaluate multiple domains simultaneously for business legitimacy, DNS security configuration, or web presence — especially for lead qualification workflows, cold outreach pre-screening, or vendor due diligence. It is preferred over single-domain lookups when processing lists of two or more domains, and over generic WHOIS tools when you need combined DNS security audit (SPF/DMARC) and business qualification signals in one call.
Side effects
- Domain not resolvable — DNS lookup fails for invalid or nonexistent domains, reflected in failed count
- Rate limiting or quota exceeded for high-volume batch requests
- Malformed domain input causes individual result failures while others succeed
- Payment failure via x402 protocol prevents the call from executing
- Partial success — some domains return results while others fail, tracked via failed vs successful counts
