How this service works
One call for an address on Base: USDC balance, ETH balance, verified primary Basename, transaction count (nonce) and whether it is a contract. Use it to profile a counterparty or payout wallet before interacting. Replaces four or five separate reads with a single priced request. Query: ?address=0x...
Output
A single JSON response containing: USDC balance (as a formatted amount), ETH balance, the verified primary Basename (if set), total transaction count (nonce), and a boolean flag indicating whether the address is a smart contract or an externally owned account (EOA).
Example use cases
Vet a counterparty before payment
“Before I send 500 USDC to 0xAbCd1234567890AbCd1234567890AbCd12345678 on Base, can you check their wallet — is it a real account with some history, what are their balances, and do they have a Basename?”
Verify a payout wallet in a workflow
“I need to confirm that 0x1111222233334444555566667777888899990000 on Base is a valid recipient — check if it's a contract, how many transactions it's made, and what its ETH and USDC balances are.”
Research a DeFi protocol address
“Can you profile the Base address 0xDeAdBeEf00000000000000000000000000000001 for me — I want to know if it's a smart contract, its Basename, transaction count, and current balances?”
Technical details
Endpoint
GEThttps://89-116-220-218.sslip.io/base/address-intel?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need multiple data points about a Base address (balances, Basename, nonce, contract status) in a single request, rather than making four or five separate RPC calls or API lookups. It is ideal for pre-interaction due diligence on counterparty or payout wallets on Base mainnet, and saves latency and cost compared to chaining individual endpoints.
Side effects
- Invalid address format (not 0x + 40 hex chars) returns a validation error
- Address with no on-chain activity returns zero balances and null Basename
- RPC node unavailability may cause timeout or 5xx error
- Payment failure or insufficient USDC for the $0.01 fee blocks the request via x402 flow
