How this service works
Basename resolution both ways: name to address, or address to primary name
Output
Returns the resolved counterpart: for a Basename input, returns the linked Ethereum (0x) address; for an address input, returns the primary Basename registered to it. Includes the canonical resolution result and any metadata the registry provides.
Example use cases
Resolve Basename to wallet address
“I need to send crypto to jesse.base.eth — can you look up what 0x address that basename resolves to?”
Reverse lookup address to Basename
“I have the address 0x1234abcd...5678 — what's the primary Base name (basename) registered to it, if any?”
Verify identity before payment
“Before I send funds, can you confirm that vitalik.base.eth is a real registered basename and tell me its resolved address?”
Technical details
Endpoint
GEThttps://agenttoll.app/api/base/name/jesse.base.ethWhen to prefer
Use this endpoint when you need fast, cheap ($0.001 USDC) bidirectional resolution between Base blockchain names (base.eth Basenames) and 0x addresses. Prefer it over generic ENS resolvers when operating on the Base L2 network specifically. Ideal for agents handling payments, identity verification, or user lookups in Base-native applications.
Side effects
- Name not registered — returns null or 404 if the Basename doesn't exist on Base
- No primary name set — an address may have no reverse record, returning empty result
- Invalid input format — malformed address or unsupported name format returns an error
- Network or registry outage — Base RPC or ENS resolver temporarily unavailable
- Rate limiting — exceeds allowed call frequency, returns 429
