How this service works
Pay-per-call AI services via the 402 Payment Required protocol. No accounts, no API keys — just USDC on Base.
Output
Returns a JSON array of on-chain events for the given wallet, where each event includes the event type (e.g. erc20_transfer), the asset involved (e.g. USDC), the amount, and the direction (in or out).
Example use cases
Monitor wallet funding confirmations
“Has the wallet 0xAbCd1234567890abcdef1234567890abcdef1234 received any USDC on Base in the last few events? I need to confirm a payment came through.”
Audit agent treasury activity
“Pull the on-chain events for the address 0xDeadBeef1234567890abcdef1234567890abcdef on Base and list all the ERC-20 transfers so I can see what went in and out of our agent's wallet.”
Track token movements on Ethereum
“Show me the latest on-chain transfer events for 0x9876543210fedcba9876543210fedcba98765432 — I want to see if any tokens moved recently, check it on Ethereum.”
