How this service works
Basename/ENS resolution on Base: forward name->address (give 'name') or reverse address->name (give 'address', forward-verified against spoofing).
Output
Returns the resolved Ethereum address for a given Basename/ENS name (forward lookup), or the verified Basename/ENS name for a given Ethereum address (reverse lookup, with forward-verification to prevent spoofing attacks). Response indicates whether resolution succeeded and provides the canonical result.
Example use cases
Verify wallet identity during payments
“I'm about to send tokens to someone named 'alex.base.eth' — can you resolve that to their actual wallet address and make sure it's not a spoofed name trying to trick me?”
Find user profile from wallet address
“A user just connected their wallet 0x1234567890abcdef1234567890abcdef12345678 to our app. What's their registered Basename so we can display their human-readable name?”
Batch resolve team member wallets
“I have a list of Basename names from our DAO members like 'alice.base.eth', 'bob.base.eth', and 'carol.base.eth' — can you convert all of them to their Ethereum addresses so I can set up permissions?”
Technical details
Endpoint
GEThttps://api.agentstools.dev/resolveWhen to prefer
Use this endpoint when you need to resolve Basename or ENS identities specifically on the Base network, especially when anti-spoofing guarantees for reverse lookups are important. Prefer this over generic ENS resolvers when working in the Base/Coinbase ecosystem or when you need forward-verified reverse lookups to prevent identity spoofing.
Side effects
- Name not found — the Basename/ENS name does not exist or is not registered
- Address has no reverse record — the address hasn't set a primary name
- Reverse record fails forward verification — spoofing attempt detected, resolution rejected
- Invalid input format — address is not a valid 0x Ethereum address or name is malformed
- Network or RPC error — Base/ENS resolution infrastructure temporarily unavailable
- Payment failure — x402 micropayment of $0.005 USDC not completed
