## 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 vextorium-margin-calculator-2de59d4e -d '<json body>'
```

Example prompt: If I buy a product for $10 and sell it at $15 for 100 units with 21% VAT, what are my margin percentage, markup percentage, unit profit, total profit, and VAT-inclusive selling price?

## When to prefer this

Choose this endpoint when you need to compute retail pricing analytics — especially when you need to simultaneously derive margin, markup, VAT-adjusted prices, and profit figures in a single call. Ideal for e-commerce agents, accounting tools, or pricing workflows where clarifying the margin/markup distinction matters. Prefer over manual formula chaining when VAT handling and multi-unit profit rollup are both needed.

## Known failure modes

- Missing required body fields returns an error
- Providing zero or negative cost/price values may produce mathematically invalid or infinite results
- Passing string values instead of numbers for numeric fields causes a schema validation error
- Omitting units defaults behavior may vary — endpoint may require explicit unit count
