How this service works
Due-diligence check on any domain: registration age via RDAP, registrar, DNS posture (A/MX/NS), SPF and DMARC presence, SSL certificate history, and risk flags like newly-registered or no-mail-setup. One call, one JSON verdict. $0.008 USDC per call, pay via x402, no API key.
Output
A JSON object containing: domain registration age and registrar info (via RDAP), DNS posture including A, MX, and NS records, SPF and DMARC record presence, SSL certificate history, and boolean risk flags such as 'newly-registered' or 'no-mail-setup'.
Example use cases
Example prompt
“Can you run a full due-diligence check on acmecorp.io — I want to know how old the domain is, who registered it, whether it has proper SPF and DMARC setup, and whether there are any risk flags I should worry about?”
Technical details
Endpoint
GEThttps://toolcall.click/t/domain/checkWhen to prefer
Use this endpoint when you need a single-call comprehensive domain intelligence snapshot covering registration, DNS, email security posture, and risk flags — especially for vendor due diligence, phishing detection, or evaluating whether an unfamiliar domain is legitimate. Prefer this over manual WHOIS or separate DNS tools when you need an aggregated risk verdict in one JSON response without managing multiple API keys.
Side effects
- Domain not found or unregistered — empty or null RDAP response
- Invalid domain format passed as query parameter — likely a 400 error
- RDAP or DNS lookup timeout — partial data or error flag in response
- Payment failure via x402 — request not processed
- Rate limiting or service unavailability — 5xx response
