Call when an agent needs ERC-20 Transfer logs on Base filtered by token and/or w
Call when an agent needs ERC-20 Transfer logs on Base filtered by token and/or wallet over a bounded block range (default the latest 2000 blocks, max 10000, at most 50). Amounts are raw and human when decimals() is readable. Read-only. No spend. Send JSON {"token":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","wallet":"0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"}. Exact $0.005 USDC on Base. Try unpaid POST /v1/sandbox/base-erc20-transfers first.
