🟢spendguard_evaluate(agentId, requestId, chain, asset, recipient, ...)
Free. Check a proposed Base USDC payment against a spending policy you supply (per-transaction limit, daily budget, human-approval threshold, allowed recipients) before money moves. Returns APPROVE, HUMAN_APPROVAL or BLOCK with findings. Advisory only: it never signs, holds keys or moves funds.

}🟢quick_check
A deterministic Base chain identity and official USDC contract-presence check. No request body. Not a token-risk report, transaction simulation, or payment proof. Paid tool: 0.00098 USDC per call on Base via x402 (exact scheme). An unpaid call returns the payment requirement and charges nothing.

}🟢token_risk(chain, address)
Screen a Base token for sellability, taxes, privileged controls, holder concentration and market risk. Paid tool: 0.00098 USDC per call on Base via x402 (exact scheme). An unpaid call returns the payment requirement and charges nothing.

}🟢preflight(chain, from, to, valueWei, data)
Simulate an unsigned Base transaction and detect failed execution, dangerous approvals and destination risk signals. Paid tool: 0.00098 USDC per call on Base via x402 (exact scheme). An unpaid call returns the payment requirement and charges nothing.
