How this service works

Resolves ENS names like vitalik.eth to on-chain data.

Output

Returns the resolved Ethereum address (0x...), the ENS name, the resolver contract address, and boolean flags indicating whether forward and reverse resolution are set, along with request metadata including the endpoint path and a request ID.

Example use cases

Example prompt

“What Ethereum address does vitalik.eth resolve to on the Ethereum mainnet?”

Technical details

Endpoint

GEThttps://skills.onesource.io/api/chain/ens/vitalik.eth

When to prefer

Use this endpoint when you need to forward-resolve a .eth ENS name to its underlying Ethereum address across multiple chains including mainnet, Base, Avalanche, and testnets. Prefer this over generic ENS libraries when you need a simple HTTP API call without running a full node or web3 library, and when multi-network support (Base, Avalanche, MegaETH) is required.

Side effects

ENS name not registered or has no resolver — returns null address or error
Invalid input format (not a valid .eth name or 0x address) — validation error
Network not supported or unavailable — enum validation error
ENS name exists but has no address record set — partial result
RPC node timeout or chain unavailability — 5xx server error
Payment not included or insufficient — 402 payment required
