}🟢address_profile(chain, address)
Preflight any address on Base or Arc before paying or approving it: EOA vs contract vs EIP-7702-delegated wallet, EIP-1967 proxy implementation/admin, owner(), Safe multisig threshold, ERC-20 metadata, USDC + native balance, Sourcify verification, and risk flags. Costs $0.005 USDC on Base per call via x402 (unpaid calls return the x402 PaymentRequired; any x402 MCP client pays automatically).

}🟢verify_usdc_payment(chain, tx, to, minAmount, from, ...)
Verify that a transaction paid at least N USDC to an address on Base or Arc (handles Arc native-USDC logs). Returns verified true/false, confirmations, matching transfers and reasons. Use it to confirm a customer paid before delivering. Costs $0.003 USDC on Base per call via x402 (unpaid calls return the x402 PaymentRequired; any x402 MCP client pays automatically).
