How this service works
Pay-per-call utilities for AI agents over x402, USDC on Base.
Output
A JSON object containing: domain registration status, registrar name, creation and expiry timestamps (from RDAP/WHOIS), DNS records (A, AAAA, MX, NS), email security records (SPF string, DMARC value), and HTTPS reachability status with HTTP status code — all in a single response.
Example use cases
Phishing domain triage
“I just got a suspicious email from support@paypa1-secure.com — can you check that domain? I want to know how old it is, who registered it, whether it has real MX records, and if it has SPF or DMARC configured so I can tell if this looks like a phishing setup.”
Sales lead domain qualification
“Before I reach out to the company at techventures.io, can you pull up the domain details — registration date, registrar, whether their email is properly secured with SPF and DMARC, and if their site is actually live over HTTPS?”
Vendor due diligence check
“We're about to sign a contract with a vendor at globalparts-supply.com — can you run a full domain check on them? I need the registration date, expiry, nameservers, MX records, and whether they have email authentication set up.”
Technical details
Endpoint
GEThttps://agents.crowdspark.me/v1/domain/lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a comprehensive, all-in-one domain intelligence snapshot — combining WHOIS registration data, full DNS record resolution, email security posture (SPF/DMARC), and HTTPS reachability in a single API call. Prefer it over individual DNS or WHOIS tools when you need correlated data for due diligence, phishing investigation, or lead research workflows where making multiple separate API calls would be inefficient.
Side effects
- Domain not found or not registered — returns registered: false with empty DNS records
- Invalid domain format — returns a 400-level error
- RDAP/WHOIS data unavailable for some TLDs — registration fields may be null
- DNS resolution timeout — individual record types may be missing
- Rate limiting — 429 response if too many requests are made in a short period
