Parameters from the server's own tool schema.
This tool is directly involved in financial decision-making for agent payments — it produces approval artifacts that gate real agent spend over x402/USDC payment routes. Although it claims to be deterministic and never sends payment headers itself, its primary purpose is to authorize and configure financial transactions (go/no-go decisions on real spend, repeat purchase policies, payment runbooks).

Attacks that exploit this kind of access
Turn a live x402 paid route, buyer budget, expected payTo/network/asset, runtime, and receipt policy into an agent-payment due diligence pack: dueDiligenceDecision, goNoGoPolicyPack, clientCompatibilityAdapter, receiptEvidencePolicy, repeatPurchasePolicy, firstPaymentRunbook, MCP/Flowise guard configs, and stop conditions. Built for teams that see x402 quotes but need one machine-readable approval artifact before allowing real agent spend. This deterministic endpoint never asks for private keys and never sends a payment header to the target service. Pay up to $0.019 per request with x402 USDC on Base or choose the fixed-price Solana USDC option when advertised. Exact fixed-price payment and Base upto token-metered payment are both accepted when clients support them; upto settlements use actual response usage, a 0.0001 minimum, and the selected tier price as the cap. Canonical live prices: https://gpt55.558686.xyz/x402/live-prices.json. It is categorised as a Financial tool in the GPT 5 5 x402 Low Cost Agent Tools MCP Server, which means it involves financial transactions. Block by default and require explicit approval.
