KushBitx AgentProof
Fast pre-payment sanity check for agents on Base: confirms the RPC reports Base mainnet (chain ID 8453) and that the official USDC contract has deployed code. No request body. Returns PASS or FAIL with both checks and a timestamp. It is not a token-risk report, transaction simulation or payment proof.
