Example prompt: Can you calculate the bundle contribution for a retail bundle priced at $100, where item costs are $50, packing cost is $5, and fulfilment cost is $10?

## When to prefer this

Use this endpoint when you need a fast, local, single-shot calculation of bundle contribution margin for retail scenarios — particularly when you only have the four key cost/price inputs and don't need live inventory, platform fee lookups, or order execution. Ideal for quick profitability checks, pricing decisions, or lightweight scenario analysis without connecting to a live commerce platform.

## Known failure modes

- Missing required fields (bundle_price, item_costs, packing_cost, fulfilment_cost) returns a validation error
- Values exceeding maximum limit of 1,000,000,000,000 are rejected
- Negative values are not accepted (minimum is 0)
- Non-numeric inputs for cost or price fields will cause schema validation failure
