How this service works

Resolve ENS name to address and records

Output

Returns the resolved Ethereum wallet address and associated ENS records (e.g. avatar, email, content hash, social handles) for the given ENS name

Example use cases

Example prompt

“What Ethereum address does vitalik.eth resolve to? Can you look up all the ENS records for that name too?”

Technical details

Endpoint

GEThttps://api.web3identity.com/api/ens/resolve/base.eth

When to prefer

Use this endpoint when you need to resolve a human-readable ENS name (e.g. alice.eth, base.eth) to its underlying Ethereum address or retrieve its associated profile records. Prefer this over on-chain lookups when you need a simple HTTP API without managing your own Ethereum node or web3 provider. Ideal for agents that need to identify wallet addresses from social/human-readable identifiers in the Ethereum ecosystem.

Side effects

ENS name does not exist or has not been registered — returns 404 or null address
ENS name is expired — may return stale or empty records
Network or RPC timeout when querying Ethereum — returns 503 or timeout error
Invalid ENS name format provided — returns 400 bad request
Name exists but has no resolver set — returns empty records

Input

{
  "name": "vitalik.eth"
}

Output

{
  "name": "base.eth",
  "cached": true,
  "address": "0x14536667Cd30e52C0b458BaACcB9faDA7046E056",
  "cachedAt": "2026-06-12T03:55:08.029Z"
