Turn agent spending rules into a buyer-owned payment policy: spend caps, service allowlist, payTo and network checks, MCP guard config, Flowise guard config, x402 prepay checklist, denial examples, and audit log schema. This deterministic endpoint does not call an upstream model. Pay up to $0.012 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.
