How this service works
Resolve an ENS name to an Ethereum address
Output
Returns the resolved Ethereum wallet address (0x... format) corresponding to the given ENS name, allowing the agent to map a human-readable name to an on-chain address.
Example use cases
Verify recipient identity before crypto transfer
“I need to send 5 ETH to alice.eth but want to make sure I have the right wallet address first—can you look up what Ethereum address that ENS name resolves to?”
Cross-reference ENS name with on-chain activity
“I found this ENS name 'defi-trader.eth' mentioned in a forum post about a smart contract exploit. Can you resolve that to an actual wallet address so I can check their transaction history?”
Authenticate user during onboarding flow
“A user just submitted their profile with the ENS name 'creator.eth' as their web3 identity. Resolve that to an Ethereum address so we can verify they actually control that domain.”
Technical details
Endpoint
GEThttps://x402-gateway-production.up.railway.app/api/ens/resolveWhen to prefer
Use this endpoint when you need to translate a human-readable ENS name (e.g. alice.eth) into an Ethereum address for payment, verification, or on-chain interaction purposes. Prefer this over manual RPC calls when operating in an agentic context with x402 micropayment support.
Side effects
- ENS name not found or unregistered — returns null or error
- ENS name has no address record set — resolves but returns empty
- Invalid ENS name format — returns validation error
- Network or resolver timeout — returns 5xx error
- ENS name exists but points to a contract, not an EOA
