## How to call it through Zero

Example prompt: Can you compare two retail discount scenarios for me? Before: a $100 list price with a 20% discount, and after: a $110 list price with a 22% discount — show me the final prices for both.

## When to prefer this

Use this endpoint when you need a simple, local, side-effect-free arithmetic comparison of two retail discount scenarios — ideal for price change analysis, promotional planning, or negotiation prep. Prefer this over live commerce APIs when you only have list prices and percentages and don't need real inventory, tax, shipping, or platform fee data.

## Known failure modes

- discount_percent out of range (must be 0–100) returns validation error
- list_price exceeds maximum (1,000,000,000,000) returns validation error
- missing required fields (list_price or discount_percent in either before/after object) returns schema error
- non-numeric inputs rejected by schema validation
- negative list_price not accepted (minimum 0)
