## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agenttools-margin-calculator-e4f00693
```

Example prompt: What's the profit margin and markup on a product that costs me $40 to make and I sell for $65 — I always mix those two up and want both numbers.

## When to prefer this

Use this endpoint when an agent needs both profit margin and markup computed together from a cost and price — especially when the user needs to understand the difference between the two. It is ideal for pricing decisions, financial reporting, and retail/e-commerce contexts where confusing margin and markup is a common error.

## Known failure modes

- Missing required 'cost' or 'price' query parameter returns a 400 error
- Non-numeric values for cost or price result in a validation error
- Price of zero may cause division-by-zero in margin calculation
- Negative cost or price values may produce unexpected or undefined results
- API returns a 402 Payment Required if the x402 micropayment is not provided

## How this service works

Calculate gross profit, profit margin (profit as % of price) and markup (profit as % of cost) from a unit cost and selling price — the two numbers people constantly mix up. Use this when an agent needs to profit margin vs markup, both computed.

## Output

Returns gross profit (price minus cost), profit margin as a percentage of the selling price, and markup as a percentage of the cost — clearly distinguishing the two figures that are commonly confused.
