How this service works
Resolve ENS name to Ethereum address or reverse-resolve address to ENS name
Output
Returns the resolved Ethereum address for a given ENS name, or the ENS name associated with a given Ethereum address, depending on which input was provided.
Example use cases
Example prompt
“What Ethereum address does vitalik.eth resolve to? Also, can you reverse-resolve 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 to get its ENS name?”
Technical details
Endpoint
GEThttps://ens-resolver.api.klymax402.com/api/resolveWhen to prefer
Use this endpoint when you need to resolve a human-readable ENS name (e.g. vitalik.eth) to its underlying Ethereum address, or when you have an Ethereum address and want to find its associated ENS identity. Ideal for enriching wallet data with human-readable names, verifying ENS ownership, or preparing transactions using ENS names.
Side effects
- ENS name does not exist or has no resolver set — returns null or error
- Ethereum address has no reverse ENS record set — returns null
- Invalid ENS name format — returns validation error
- Invalid Ethereum address format — returns error
- ENS name exists but has no address record — returns null
- Network or RPC timeout when querying Ethereum mainnet
