How this service works
Determine a domain's age from registration data and archival history — tries RDAP, then port-43 WHOIS, then a Wayback-based estimate (age_source: rdap | whois | wayback_estimate | null), returning creation date, age in years, first Wayback capture, archived snapshot count, and a maturity signal so agents can assess trustworthiness and detect freshly registered domains used for fraud or phishing — including .io and TLDs without public RDAP.
Output
A JSON object with the domain's age in days and years, ISO 8601 creation date (from RDAP or similar source), first Wayback Machine archive date, estimated total archive snapshots, registration-to-archive gap in days, a maturity label (e.g. 'established'), a numeric score (0–100), and a letter grade (A–F).
Example use cases
Example prompt
“Can you check how old the domain shopify-deals-today.com is — I want to know when it was registered, how mature it is, and what grade it gets for domain age?”
Technical details
Endpoint
GEThttps://netintel.dev/domain-age/check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a structured, scored assessment of a domain's age and historical presence — especially for fraud detection, phishing link analysis, vendor vetting, or trust scoring pipelines. Prefer this over raw WHOIS lookups when you want a normalized grade and maturity label rather than raw registry text.
Side effects
- Domain not found in RDAP or WHOIS — may return partial data or error
- Invalid domain format returns a 400 Bad Request
- Very new domains with no archive history may return null for archive fields
- Payment failure via x402 returns HTTP 402 before any domain data is fetched
- Rate limiting or network timeouts may occur for high-volume calls
