How this service works
Bundled execution of the Domain age and legitimacy workflow - How old and legit is this domain? WHOIS registration, DNS resolution, and TLS certificate in one pass. One x402 payment runs 3 underlying tools (whois, dns-lookup, tls-cert); partial-success per step.
Output
A bundled result containing WHOIS registration data (including domain creation date and registrar), DNS resolution status, and TLS certificate details — giving a composite picture of the domain's age and legitimacy.
Example use cases
Example prompt
“Can you check how old and legitimate the domain 'suspicioussite.net' is — I want to see its WHOIS registration date, DNS resolution, and TLS certificate all in one go?”
Technical details
Endpoint
POSThttps://agent402.tools/api/skill/domain-ageWhen to prefer
Use this endpoint when you need a comprehensive single-pass assessment of a domain's age and legitimacy, combining WHOIS, DNS, and TLS signals without making three separate API calls. Ideal for phishing detection, vendor vetting, or trust scoring workflows where all three signals are needed together.
Side effects
- Domain not found or unregistered — WHOIS returns no records
- DNS resolution failure for the domain
- TLS certificate absent or expired
- Invalid domain string format in input
- Partial results if one of the three sub-tools (whois, dns-lookup, tls-cert) fails
