Call when an agent needs ERC-20 name, symbol, decimals, and totalSupply for one
Call when an agent needs ERC-20 name, symbol, decimals, and totalSupply for one Base token. Send token (example Circle USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). Read-only eth_call on eip155:8453. Not a contract, or no ERC-20 methods, errors. No spend. Send JSON {"token":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913"}. Exact $0.003 USDC on Base. Try unpaid POST /v1/sandbox/base-erc20-meta first.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
