How this service works
Pay-per-call machine utilities for autonomous agents.
Output
A structured JSON intelligence pack containing: DNS records (A, AAAA, MX, NS, TXT), parsed SPF and DMARC mail posture, a markdown excerpt of the domain's homepage, and a heuristic domain health assessment. All data is derived from public lookups only.
Example use cases
Vetting a vendor domain before outreach
“Before we send cold emails to leads at acmecorp.io, can you check their domain's DNS records and whether they have SPF and DMARC properly set up so I know if our emails will likely reach them?”
Competitor domain profile research
“Pull a full intelligence pack on notion.so — I want to see their DNS records, mail configuration, a snippet of their homepage, and how healthy the domain looks overall.”
Checking email deliverability risk
“We're about to add mailchimp.com to our suppression list — first, can you check their DMARC and SPF posture and any relevant DNS records so I can confirm it's a legit sending domain?”
Technical details
Endpoint
POSThttps://agent-vending-production.up.railway.app/v1/domain-intelligence?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, multi-signal domain profile in a single call — combining DNS records, email security posture (SPF/DMARC), a homepage excerpt, and health heuristics. It is ideal for pre-outreach domain vetting, vendor due diligence, or competitive research where you want structured intelligence rather than raw DNS queries or email-address-level validation. Prefer it over a standalone email validator when the target entity is a domain rather than a specific address.
Side effects
- Private, loopback, or local domain targets are rejected with a validation error
- Domain not found or DNS resolution failure returns an empty or partial record set
- Homepage fetch may fail for domains with bot-blocking or non-standard HTTP configurations
- DMARC/SPF fields may be absent if the domain has not configured them
- Transient DNS resolution timeouts may cause partial results
