How this service works
Pay-per-request AI, crypto, proxy, and utility APIs using x402 protocol
Output
Returns a JSON object containing the expiration/expiry date and registration details for the queried ENS domain name, indicating when the name was last registered and when it will expire or become available for re-registration.
Example use cases
Monitor portfolio of ENS domains
“I own several ENS names for my business. Can you check which ones are expiring soon and need renewal attention?”
Verify ENS availability before purchase
“I want to buy the ENS name 'mycompany.eth' but first check if it's currently registered and when it would become available.”
Audit Web3 project's domain status
“Pull up the expiration dates for all these ENS domains tied to our DAO treasury and see which ones are at risk.”
Technical details
Endpoint
POSThttps://x402.onchainexpat.com/api/x402-crypto/ens-expiryWhen to prefer
Use this endpoint when you need a quick, pay-per-use lookup of an ENS domain's expiry date without setting up your own Ethereum node or ENS SDK integration. Ideal for agents that only occasionally need ENS expiry data and want to avoid infrastructure overhead. At $0.01 USDC per call via x402, it is cost-effective for low-volume lookups.
Side effects
- Invalid or malformed ENS name returns an error
- ENS name not found or never registered returns empty or null expiry
- Payment failure via x402 protocol returns 402 status
- Network or blockchain RPC error causes timeout or 500 error
- ENS name with non-.eth TLD may not be supported
