## 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-markup-calculator-2a273d28
```

Example prompt: My product costs me $35 to make and I sell it for $60 — can you tell me both the profit margin and the markup percentage so I understand the difference?

## When to prefer this

Choose this endpoint when you need both profit margin and markup computed simultaneously from cost and price inputs — especially useful when users conflate the two metrics. Ideal for quick pricing calculations in e-commerce, retail, freelance, or manufacturing contexts without needing a full accounting system.

## Known failure modes

- Missing required 'cost' or 'price' query parameter returns an error
- Non-numeric values for cost or price cause a validation error
- Zero cost value may cause division-by-zero for markup calculation
- Negative values may return unexpected or undefined results
- Service unavailability due to Vercel hosting downtime

## 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 (selling price minus cost), profit margin as a percentage of selling price, and markup as a percentage of cost — giving both figures that are frequently confused with one another.
