How this service works
Domain registration age + registrar via RDAP: registration date, age in days/years, expiry date, registrar name for any domain. Paid per call: $0.002 USDC on Base, Monad, Arbitrum, Optimism, Polygon, Avalanche or Solana (eip155:8453) via x402 v2 (exact scheme, EIP-3009). Unpaid requests return HTTP 402 with machine-readable payment instructions; the buyer signs the EIP-3009 authorization off-chain and retries with the PAYMENT-SIGNATURE header. The facilitator pays the gas, so the buyer needs no ETH. No API key.
Output
A JSON object containing the domain name, registration date (ISO 8601), expiry date (ISO 8601), age in days, age in years, registrar name, RDAP service identifier, and the timestamp of when the check was performed.
Example use cases
Vetting a domain before acquisition
“I'm thinking about buying shopnow.com — can you tell me how old the domain is, when it was first registered, and when it expires?”
Fraud detection for new signups
“A user just signed up with the domain quickloans247.biz — can you check how old that domain is and who registered it? I want to know if it looks suspicious.”
Competitive research on rival sites
“How long has competitor.com been around? Find out when it was registered, its age in years, and who the registrar is.”

Endpoint
GEThttps://rdap.hsharmanov02.workers.dev/age?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, machine-readable domain age and registrar data without requiring an API key. It is ideal for agents that need to enrich domain metadata, perform fraud checks, or research domain histories programmatically. Prefer this over WHOIS-based tools when you need consistent JSON output and RDAP compliance.
Side effects
- Domain not found in RDAP — returns error or empty response
- Domain registry does not support RDAP — lookup may fail
- HTTP 402 returned if payment is not included or payment signature is invalid
- Malformed domain input causes query failure
- RDAP registry temporarily unavailable causing timeout
