How this service works
Resolve an ENS .eth name to its address (plus avatar, url and twitter records), or an address to its verified primary ENS name. Reads Ethereum mainnet via the ENS Universal Resolver.
Output
Returns the resolved Ethereum address for a forward lookup (ENS name → address), or the verified primary ENS name for a reverse lookup (address → name), along with optional text records including avatar, URL, and Twitter handle stored in the ENS registry on Ethereum mainnet.
Example use cases
Resolve ENS name before sending crypto
“Before I send ETH, can you look up what address corresponds to nick.eth so I'm sending to the right wallet?”
Identify wallet owner by ENS name
“I have the Ethereum address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — does it have a verified primary ENS name registered on mainnet?”
Enrich user profile with ENS metadata
“Look up the ENS profile for brantly.eth and tell me the avatar image, website URL, and Twitter handle stored in its records.”
Technical details
Endpoint
POSThttps://dt0ur.online/api/onchain/ens?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve ENS .eth names to Ethereum addresses or perform reverse ENS lookups on Ethereum mainnet. It also fetches enriched profile records (avatar, URL, Twitter) in a single call, making it ideal when you want full ENS profile metadata rather than just an address. Prefer this over raw RPC calls when you need a simple, paid API abstraction without managing your own Ethereum node or ENS SDK.
Side effects
- ENS name not registered or expired — returns null or empty address
- Address has no primary ENS name set — reverse lookup returns nothing
- Malformed ENS name or invalid Ethereum address — input validation error
- ENS Universal Resolver RPC timeout or Ethereum node unavailability
- Name resolves but has no avatar/URL/twitter records set — partial results returned
