How this service works
ENS name resolution + reverse lookup via public Ethereum RPC.
Output
Returns the resolved Ethereum address for a given ENS name, or the associated ENS name for a given Ethereum address, queried live from the Ethereum network via public RPC.
Example use cases
Resolve ENS before sending crypto
“Before I send ETH to friend.eth, can you resolve that ENS name to its actual Ethereum address so I know I'm sending to the right place?”
Reverse lookup wallet identity
“I have this Ethereum address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — does it have an ENS name associated with it?”
Verify ENS ownership for dApp login
“Check what address the ENS name myproject.eth currently points to — I want to confirm ownership before granting admin access.”
Technical details
Endpoint
GEThttps://shelf.thirdmade.net/probe/ens-lookupWhen to prefer
Choose this endpoint when you need real-time, live ENS name resolution or reverse lookup against the Ethereum mainnet without running your own node. It is ideal for agents that need to translate human-readable ENS names to addresses before executing transactions, or to identify the human-readable identity behind a wallet address.
Side effects
- ENS name not registered — returns null or empty resolution
- Address has no reverse ENS record set — returns no name
- Invalid ENS name or malformed address — returns error
- Public Ethereum RPC unavailable or rate-limited — timeout or 5xx error
- ENS name exists but has no address resolver set — returns null
