How this service works
Base wallet lookup: an address's primary basename, ETH balance, transaction count, and whether it is a contract
Output
Returns a structured snapshot of the Base address including its current ETH balance, total number of outgoing/incoming transactions, and a flag indicating whether the address is a smart contract or an externally owned account (EOA).
Example use cases
Pre-transfer wallet sanity check
“Before I send funds, can you check if 0xAbCd1234abcd1234abcd1234abcd1234abcd1234 is a real active wallet on Base — what's its ETH balance and how many transactions has it done?”
Smart contract address verification
“I have this Base address 0xDEADBEEFdeadbeefdeadbeefdeadbeefDEADBEEF — can you tell me if it's a smart contract or just a regular EOA, and what's its current ETH balance?”
Portfolio balance monitoring
“Check the current ETH balance and transaction count on Base for 0xaabbccddaabbccddaabbccddaabbccddaabbccdd so I can track how active that wallet has been.”
Technical details
Endpoint
GEThttps://agenttoll.app/api/base/address/:addressWhen to prefer
Use this endpoint when you need a quick, single-call snapshot of a Base network address — its ETH balance, transaction count, and contract/EOA classification — without needing full transaction history or token balances. Ideal for agents doing lightweight address profiling, pre-transfer checks, or building dashboards on Base chain data. The $0.001 per-call pricing and x402 protocol make it suitable for high-frequency automated lookups.
Side effects
- Invalid address format (not matching 0x + 40 hex chars) returns a 400 error
- Address not found or never used on Base may return zero balances
- Network or RPC node downtime may result in timeouts or 5xx errors
- Payment not processed correctly (x402 protocol failure) results in 402 response
