Evaluate a new product idea for Amazon US using demand evidence, competitive barriers, unit economics, advertising assumptions, operational constraints, and compliance risk. Use when a user asks for Amazon US product research, product selection, launch feasibility, FBA profitability, opportunity scoring, Go/Validate/No-Go recommendations, or comparison of several candidate products. Accept user-provided assumptions, research notes, CSV/JSON data, or marketplace evidence; never represent estimates as live Amazon data.
