How this service works
Resolve an ENS name or Basename to an address (plus url/twitter/github text records), or reverse-resolve an address to its primary name.
Output
Returns the resolved Ethereum address for a given ENS name or Basename, along with any text records stored on-chain (URL, Twitter handle, GitHub username). For reverse lookups (0x address input), returns the primary ENS or Basename associated with that address.
Example use cases
Humanize a wallet address
“I have this Ethereum address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — can you look up its primary ENS name so I know who I'm dealing with?”
Verify recipient before sending crypto
“Before I send funds to jesse.base.eth, can you resolve that Basename to an actual 0x address so I can double-check it's right?”
Fetch social links from ENS profile
“What URL, Twitter, and GitHub accounts are listed in the ENS profile for nick.eth?”
Technical details
Endpoint
GEThttps://automaton-tx-explainer.vercel.app/v1/ens?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve human-readable Ethereum names (ENS or Base Basenames) to addresses, or reverse-resolve a 0x wallet address to its primary name, particularly when you also want associated social/profile text records (Twitter, GitHub, URL). Prefer this over general blockchain explorers when you specifically need ENS/Basename identity resolution with social metadata in a single lightweight call.
Side effects
- Name not found or unregistered — resolver returns null/empty address
- Address has no primary name set — reverse lookup returns empty
- Invalid input format — query rejected if neither a valid ENS/Basename nor a 0x address
- Text records not set — fields like twitter/github may be missing from response
- RPC or upstream node timeout causing delayed or failed resolution
