How this service works
Pay-per-call utility APIs in USDC on Base: Hebrew calendar and text tools, Shabbat times, Base token control-risk screen and address summary, plus finance arithmetic tools. General information and arithmetic only; not investment, tax or legal advice and not a recommendation to buy, sell or hold anything.
Output
A JSON object containing: chain name ('base'), transaction count (integer), ETH balance (string), USDC balance (string), and a boolean flag indicating whether the address is a smart contract.
Example use cases
DeFi counterparty risk screening
“Before I send funds, can you check this Base address 0xAbCd...1234 and tell me its ETH and USDC balances, how many transactions it's had, and whether it's a contract?”
Wallet activity audit
“I need a quick summary of what's going on with Base wallet 0x9F3a...beef — transaction count, balances, and is it a regular wallet or a smart contract?”
New user onboarding verification
“Can you verify that my newly created Base address 0x4E7c...cafe actually has zero balances and no transaction history yet?”
