How this service works
ENS in one call: resolve a name to an address, or an address to its primary name — Genesis402 / UnyKorn Operator Network
Output
Returns either the resolved Ethereum address (0x-prefixed) for a given ENS name, or the primary ENS name (e.g. example.eth) for a given Ethereum address. If no resolution exists, the response will indicate the name or address could not be resolved.
Example use cases
Resolve ENS name before sending funds
“I want to send ETH to vitalik.eth — can you look up the actual 0x wallet address that ENS name resolves to so I can confirm it before sending?”
Identify wallet owner by ENS name
“I have this Ethereum address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — does it have a primary ENS name registered?”
Validate ENS name in user onboarding
“A user typed 'myname.eth' as their payment address — can you resolve it to a real 0x Ethereum address so I can verify it's valid and store the on-chain address?”
Technical details
Endpoint
POSThttps://twin.unykorn.org/chain/ens?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, single-call ENS forward or reverse resolution without setting up your own Ethereum RPC node or ENS SDK. It is ideal for AI agents that need to translate human-readable ENS names to wallet addresses (or vice versa) on demand, especially in pay-per-call agentic workflows using the x402 protocol. Prefer this over raw RPC calls when you want a managed, metered API without infrastructure overhead.
Side effects
- ENS name does not exist or has no resolver set — returns null or error
- Ethereum address has no primary ENS name registered — returns empty or null name
- Invalid ENS name format — returns validation error
- Invalid Ethereum address format (not 0x + 40 hex chars) — schema validation failure
- ENS resolution RPC timeout or node unavailability — returns service error
- Payment failure via x402 — 402 Payment Required response before resolution is attempted
