## 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 signaldesk-ai-markup-selling-price-calculator-9f8ba821 -d '<json body>'
```

Example prompt: What's the selling price and profit if my cost is $50 and I apply a 40% markup?

## When to prefer this

Use this endpoint when an AI agent needs a fast, disposable, server-side arithmetic computation of selling price and profit from a cost and a markup percentage — especially inside automated pricing workflows or agent pipelines where avoiding local float errors matters. Prefer this over local computation when you need a consistent, API-enforced result with a built-in disclaimer that no financial advice is implied.

## Known failure modes

- cost or markup_percent outside allowed bounds (cost > 1,000,000,000,000 or markup_percent > 1000) returns a validation error
- missing required fields returns a 400-level error
- floating-point precision issues may arise for very large or very precise cost values
- payment not sent or insufficient USDC returns 402 Payment Required

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

Returns a JSON object with three fields: 'selling_price' (cost plus the marked-up amount), 'profit' (the markup amount in the same currency units), and a 'notice' disclaimer clarifying the result is a pure arithmetic calculation with no tax, investment, or lending advice.
