Example prompt: My product costs me $24 to make and I'm selling it for $40 — can you calculate the profit margin, markup percentage, and profit I'm making on each unit?

## When to prefer this

Use this endpoint when you need to quickly compute pricing metrics for a product given cost and any one of price, target margin, or markup — especially useful for retail pricing, e-commerce, and business planning where you know cost and need to derive consistent margin and markup figures without building your own formula.

## Known failure modes

- Missing cost field — returns error as cost is always required
- No second parameter provided (price, marginPct, or markupPct) — system cannot solve without at least one additional input
- Contradictory inputs (e.g. both price and marginPct provided but they conflict) — may return unexpected or overspecified results
- Invalid numeric types passed — validation error
- Margin or markup values outside logical bounds (e.g. margin >= 100%) — may produce infinite or nonsensical results

## How this service works

Margin, markup, and profit from cost — give cost plus any one of price, target margin %, or markup %, and it solves the rest.

## Output

Returns the full set of pricing metrics: margin percentage, markup percentage, profit amount, and price — solving for whichever values were not provided given cost and one other input.
