How this service works
ENS resolve — turn a .eth name into an address, or an address into its primary .eth name, via eth_call on OneSource live Ethereum RPC
Output
Returns the resolved Ethereum address for a given .eth name, or the primary .eth name for a given address, along with chain-related on-chain metadata fetched via a live Ethereum RPC call.
Example use cases
Verify wallet identity from ENS name
“I need to find out what Ethereum address the vitalik.eth name resolves to so I can send funds to the right wallet.”
Find primary ENS for any address
“Can you tell me what the primary .eth name is for the wallet address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045?”
Cross-chain ENS resolution testing
“I'm building a multi-chain app and need to resolve the address for alice.eth on the Sepolia testnet to make sure it works across different networks.”
Technical details
Endpoint
GEThttps://skills.onesource.io/api/chain/ens/nick.base.eth?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve or reverse-resolve ENS names against a live Ethereum RPC across multiple networks including Ethereum mainnet, Base, Avalanche, Sepolia, and MegaETH. Prefer this over static registry lookups when you need real-time on-chain accuracy or need to resolve names on non-mainnet networks.
Side effects
- ENS name not registered or expired — returns null or empty resolution
- Address has no reverse ENS record set — no primary name returned
- Unsupported network specified — validation error on network enum
- Malformed input (invalid address format or missing .eth suffix) — 400 bad request
- RPC node unavailable or rate-limited — 5xx error
- Name resolves to zero address — indicates unset or burned registration
