How this service works
ENS .eth name status: expiry date, days left, grace period, available or not, registrant, resolver and the address the name resolves to.
Output
A JSON object containing the normalised .eth name, a boolean indicating whether it is registered, a status string (active, in_grace_period, premium_auction, available_expired, or available), the expiry timestamp, days until expiry (negative if already expired), the grace period end date, the registrant wallet address, the resolver contract address, the resolved Ethereum address, the namehash node, the labelhash, the data source, and a plain-language summary note explaining the result.
Example use cases
Snipe an expiring ENS name
“Check when nick.eth expires and how many days are left — I want to know if it's entering its grace period soon so I can register it.”
Verify ENS name before sending crypto
“Before I send ETH to rainbow.eth, can you confirm it's actively registered and tell me the Ethereum address it actually resolves to?”
Audit ENS portfolio expiry dates
“Look up the registration status of mydomain.eth — is it still active, who's the registrant, and when does the grace period end if it's already expired?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/chain/ens-expiry?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single, comprehensive ENS name status check covering expiry, availability, grace period, registrant, resolver, and resolved address in one call. Prefer it over raw blockchain RPC calls when you want a structured JSON response with plain-language interpretation and no need to handle raw contract ABIs. Ideal for agents making decisions about ENS name availability, ownership verification before sending funds, or monitoring expiry timelines.
Side effects
- Invalid or malformed .eth name returns an error
- Name not found on-chain returns available status with nulls for owner/resolver fields
- Upstream ENS node or RPC timeout causes service error
- Rate limiting or payment failure returns 402 or 429 response
