Technical details

Endpoint

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

When to prefer

Use this endpoint when you need to resolve an ENS human-readable name (e.g. vitalik.eth) to its Ethereum address or associated records. Prefer this over manual on-chain lookups or general blockchain RPCs when you want a simple REST API call with aggregated ENS record data including avatar and text records in one response.

Side effects

ENS name not found or not registered — returns 404 or null address
ENS name has expired and is no longer resolving — returns empty or error response
Invalid ENS name format — returns 400 bad request
Upstream ENS resolution network unavailable — returns 503
ENS name resolves to zero address (0x000...000) indicating unset resolver

Input

{
  "name": "vitalik.eth"
}

Output

{
  "name": "vitalik.eth",
  "cached": true,
  "address": "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045",
