How this service works
Basename lookup both ways: a name returns its address and text records, an address returns its primary basename
Output
For a name input: returns the resolved 0x wallet address and any associated text records (e.g. avatar, description, social handles). For an address input: returns the primary registered basename associated with that address.
Example use cases
Resolve basename to wallet address
“I need to send some ETH to bob.base.eth — can you look up the actual 0x wallet address that basename points to?”
Reverse-lookup address to basename
“What is the primary Base name registered to the address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045?”
Fetch identity profile from basename
“Can you pull up all the text records and profile info attached to the basename satoshi.base.eth?”
Technical details
Endpoint
GEThttps://agenttoll.app/api/base/name/:nameOrAddressWhen to prefer
Use this endpoint when you need bidirectional Base blockchain name resolution — either forward (basename → address + text records) or reverse (address → primary basename). Prefer it over generic ENS resolvers when working specifically with Base-native identities, or when you also need text records alongside the address. It is the simplest single-call solution for Base name ↔ address lookups without setting up your own RPC node.
Side effects
- Name not registered or does not exist — empty or null result
- Address has no primary basename set — returns null basename field
- Malformed input (invalid basename format or non-checksummed address) — likely 400 error
- Network or RPC resolution failure — 500 or timeout
- Rate limiting at $0.001/call threshold exceeded — payment or 402 error
