How this service works
Forward + reverse Basename resolution read from the Base L2 Resolver: turn jesse.base.eth into an address, or an address into its primary Basename. No API key required.
Output
Returns either the resolved Ethereum address (for a forward Basename lookup) or the primary Basename string (for a reverse address lookup), pulled directly from the Base L2 Resolver on-chain.
Example use cases
Resolve Basename to wallet address
“Can you look up the wallet address for vitalik.base.eth on Base?”
Reverse lookup wallet to Basename
“Do you know if the address 0x4bBa290826C253BD854121346890015097022342 has a registered Basename on Base?”
Enrich user profile with Basename
“I have a list of Base wallet addresses — can you check each one to see if they have a human-readable Basename like something.base.eth?”
Technical details
Endpoint
GEThttps://402.com.tr/api/x402/basenameWhen to prefer
Use this endpoint when you need to resolve Basenames (*.base.eth) specifically on the Base L2 network, as opposed to generic ENS resolution on Ethereum mainnet. It requires no API key, supports both forward and reverse resolution in a single endpoint, and uses the canonical Base L2 Resolver for authoritative results. Prefer it over general ENS libraries when your agent is already operating in the Base ecosystem.
Side effects
- Name not registered — Basename has no associated address
- Address has no primary Basename set — returns null or empty
- Invalid input format — malformed address or non-.base.eth name
- Network or resolver timeout — Base L2 RPC unavailable
- Payment failure — $0.01 USDC x402 payment not processed
