How this service works
ENS resolution on Ethereum mainnet. Pass name (an ASCII .eth name) to get its resolved address, or address (0x + 40 hex) to get its primary ENS name, reverse-resolved and verified forward.
Output
For a forward lookup (name → address): returns the Ethereum address the .eth name resolves to. For a reverse lookup (address → name): returns the primary ENS name registered for that address, verified by also checking the forward resolution matches.
Example use cases
Resolve ENS name before sending funds
“Before I send ETH to nick.eth, can you look up what Ethereum address that ENS name actually resolves to so I can confirm it's correct?”
Identify wallet owner by ENS name
“I have this wallet address 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B — does it have a primary ENS name registered to it?”
Verify ENS forward and reverse match
“Can you check whether the ENS name jeff.eth both resolves to 0x1234567890abcdef1234567890abcdef12345678 and that address reverse-resolves back to jeff.eth to confirm they're properly linked?”

Endpoint
GEThttps://ari001.tailb4ac3a.ts.net/v1/ventures/x402_chain_reads_v1/ens_resolve?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve ENS names to Ethereum addresses or reverse-resolve addresses to ENS names on Ethereum mainnet, with the added safety of verified forward-confirmation on reverse lookups. Prefer this over a raw RPC call when you want a simple REST API with built-in verification logic rather than constructing raw JSON-RPC calls yourself.
Side effects
- ENS name not registered or has no resolver — returns null or error
- Address has no primary ENS name set — returns empty or null
- Reverse resolution found a name but forward resolution doesn't match — verification fails
- Invalid input format (name not ending in .eth, address not matching 0x+40hex pattern) — schema validation error
- Network or RPC connectivity issues — server error response
