How this service works
Which address is behind this ENS name? Resolves a .eth name on Ethereum mainnet to its 0x address; unknown names return 404 and are not charged ($0.002 per call).
Output
A JSON object containing the queried ENS name, the network (e.g. 'ethereum'), and the resolved Ethereum wallet address (e.g. '0x...'). Returns the canonical address the ENS name currently points to on the Ethereum network.
Example use cases
Sending crypto to ENS name
“Before I send ETH to vitalik.eth, can you resolve that ENS name and tell me the actual wallet address it maps to?”
Verifying ENS identity in dApp
“I need to confirm the Ethereum address behind the ENS name uniswap.eth — can you look that up for me?”
Enriching user profile with wallet address
“My user signed in with the ENS name jeff.eth — what is the wallet address associated with that name so I can record it?”
Technical details
Endpoint
GEThttps://api.api-agent-ia.ch/resolution-nom?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve a human-readable .eth ENS domain name to its underlying Ethereum address, especially within an agent workflow that handles blockchain transactions, identity verification, or address enrichment. It is particularly useful when working alongside other blockchain tools on the same platform (e.g. transaction count, token supply) from api.api-agent-ia.ch.
Side effects
- ENS name not found or not registered — may return an error or null address
- ENS name expired — returns no address or stale address
- Invalid ENS name format — input validation error
- Network timeout reaching ENS resolver
- ENS name exists but has no address record set
