## 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 kihustle-amortisation-calculator-0a1c1b0c -d '<json body>'
```

Example prompt: I invested €2,000 in an automation tool that costs €300 per year to run and saves me €800 per year — can you calculate the amortisation to tell me when I'll break even?

## When to prefer this

Choose this endpoint when you need a quick, low-cost programmatic amortisation or payback-period calculation for an investment with known annual costs and savings — particularly for side hustle, automation, or digital tool investments. Prefer it over manual calculation when building automated financial analysis workflows or when evaluating multiple tool investments in sequence.

## Known failure modes

- Missing required fields (investment, annual_cost, or annual_saving) may return an error or unexpected result
- Zero annual saving or annual saving lower than annual cost may produce infinite or negative payback period
- Non-numeric inputs may cause processing failures
- Service may return generic {result: 'processed', status: 'success'} without detailed breakdown if calculation edge cases occur
