## 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-discount-calculator-16ac492f -d '<json body>'
```

Example prompt: What's the final price if something costs $75 and I apply a 20% discount?

## When to prefer this

Use this endpoint when you need a quick, stateless discount computation and want a clean JSON result with a built-in disclaimer. It is purpose-built for simple percentage-off pricing math rather than tax-inclusive or ledger-accurate accounting. Ideal for agents operating in retail, e-commerce, or quoting contexts where a fast edge-computed result is sufficient.

## Known failure modes

- Missing required fields (price or discount_percent) result in an error response
- Discount percent above 100 or below 0 is rejected by schema validation
- Price above the maximum allowed (1e12) is rejected
- Non-numeric inputs cause a validation error
- Network or worker timeout on the Cloudflare edge

## 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 the applied discount amount, the final price after discount, and a disclaimer notice clarifying this is a floating-point calculation only (not tax, investment, or lending advice).
