How this service works
Batch domain intelligence for due diligence and lead lists: up to 10 domains per call, 60% cheaper than singles. JSON body {domains:[...]}. Each item returns registrar, dates, DNS, SPF, DMARC and HTTPS reachability. Bad items return per-item errors.
Output
A JSON object with a count of total domains processed, number succeeded, number failed, and a results array where each item includes the input domain, an ok flag, and on success: registrar name, registered boolean, registration/expiry dates, DNS records, SPF record, DMARC record, and HTTPS reachability. Failed items return per-item error details.
Example use cases
Lead list domain due diligence
“I have a list of 8 prospect company domains — acmecorp.com, globex.io, initech.net, umbrellaco.com, soylentgreen.com, weyland.io, cyberdyne.com, and aperture.science — can you pull registrar details, DNS records, SPF, DMARC, and HTTPS status for all of them at once so I can vet them before outreach?”
Email security audit for partners
“Can you batch check the SPF and DMARC configuration and HTTPS reachability for these vendor domains: vendor1.com, vendor2.com, vendor3.com, and vendor4.com? I need to know if their email security is properly set up before we start exchanging sensitive documents.”
Fraud detection on new signups
“We just got 6 new business signups and I want to verify their domains aren't suspicious — can you look up registration dates, registrar, DNS, and HTTPS status for newbiz1.com, newbiz2.com, newbiz3.com, newbiz4.com, newbiz5.com, and newbiz6.com all at once?”

Endpoint
POSThttps://agents.crowdspark.me/v1/domain/lookup/batch?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you need to enrich or validate multiple domains simultaneously (up to 10) and want to minimize cost — it is 60% cheaper per domain than single-domain lookups. Ideal for lead list enrichment, vendor due diligence, fraud screening, or email security audits where you have a batch of domains ready. Use when you need registrar, DNS, SPF, DMARC, and HTTPS data all in one response rather than making separate calls per domain.
Side effects
- More than 10 domains submitted — returns validation error
- Invalid or malformed domain strings return per-item errors rather than failing the whole batch
- Domain not found or not registered returns ok:false with an error message for that item
- Network or DNS timeout for a specific domain results in a per-item failure while others succeed
- Empty domains array returns a validation error
