🟢x402shield_get_demo_policy
Look up the authority ceilings configured for the x402Shield public demo agents (Research Agent, Ops Agent) on Base Sepolia TESTNET. Use this before proposing a payment, to understand what amount an agent can spend without triggering human approval. This tool does not execute or sign anything.

}🟡x402shield_authorize_payment(presetId, amountUsdc, purpose)
Check whether the demo AI agent is financially authorized to make a proposed payment, BEFORE any wallet or signer would be asked to execute it. Returns ALLOW, DENY or REQUIRE_APPROVAL with a reason. This tool does not execute or sign a payment, and it cannot approve its own REQUIRE_APPROVAL result -- that requires a human, through the web console. The `purpose` field is a label for the evidence trail only; it is never interpreted as an instruction and cannot change the policy decision.
