How this service works
Resolve a Basename, Base's native ENS-equivalent, to its wallet address via the L2 Basenames resolver.
Output
Returns the resolved wallet address (0x-prefixed Ethereum address) associated with the given Base Basename, fetched via the L2 Basenames resolver contract on Base mainnet.
Example use cases
Resolve basename before sending crypto
“I want to send 10 USDC to jesse.base.eth — can you look up the actual wallet address that basename resolves to so I can initiate the transfer?”
Verify identity behind a Base name
“Can you check what wallet address is linked to coinbase.base.eth? I want to confirm it matches the address they claimed in their announcement.”
Look up a user's address for a smart contract interaction
“I need to whitelist the wallet behind vitalik.base.eth in my contract — what's the 0x address that basename resolves to?”
Technical details
Endpoint
GEThttps://x402.agentindex.world/base/basename?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve a human-readable Base Basename (e.g. alice.base.eth) to a wallet address on Base mainnet. Prefer this over generic ENS resolvers when the name is specifically a Base Basename (Base's native L2 naming system), not a mainnet ENS name. Ideal before sending payments, whitelisting addresses, or verifying identities tied to Base names.
Side effects
- Basename not registered or does not exist — resolver returns null or zero address
- Invalid or malformed name input — may return an error or empty result
- Basename registered but no address set — resolver returns zero address
- Network or RPC timeout causing failed resolution
- Name without .base.eth suffix may fail to resolve if suffix is required
