## When to prefer this

Use this endpoint when you need a quick, reliable server-side calculation of total crafting cost from parallel arrays of item quantities and per-unit prices — especially useful in game development pipelines, automation workflows, or agent systems that need to avoid implementing arithmetic locally.

## Known failure modes

- Mismatched array lengths between quantities and unit_costs may return an error or partial result
- Non-numeric values in arrays will cause validation errors
- Empty arrays may return zero or an error
- Negative quantities or costs may produce unexpected results

## How this service works

Crafting cost calculator: Calculate total crafting cost from quantities and per-unit costs.

## Output

Returns a single total crafting cost value computed as the dot product of the quantities and unit_costs arrays (sum of each quantity multiplied by its corresponding unit cost).
