Calculate expected revenue for a Zero-gated service.
AI agents use zero_pricing_calculator to commit financial operations through Zero Network MCP Server — usually the final step of a payment, billing, or trading workflow. A call moves real money.
While this tool likely only performs calculations/estimations rather than moving money directly, it is explicitly tied to financial revenue calculations in a crypto payment system. The server description emphasizes financial transactions (paywalls, payments, pricing), and the tool name 'pricing_calculator' combined with 'expected revenue' strongly implies financial domain.
From the tool's definition "Calculate expected revenue for a Zero-gated service" and the server context of "crypto-based payments", "x402 paywalls", and "per-tool MCP pricing"
