## 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

Example prompt: Can you calculate the ROI for a campaign where we spent $5,000 and generated $12,500 in profit — what's the return on investment ratio and percentage?

## When to prefer this

Use this endpoint when you need a quick, reliable ROI ratio and percentage from a known cost and gain figure. It is ideal for agents automating business reporting, KPI dashboards, or financial decision support where ROI is a required metric. Prefer this over spreadsheet calculations when building automated pipelines or when other KPI endpoints on this service are already in use.

## Known failure modes

- Missing 'cost' or 'gain' fields — returns a validation or 400 error
- Cost of zero causing division-by-zero — may return an error or undefined result
- Non-numeric inputs for cost or gain — likely returns a 422 or parsing error
- Negative gain inputs (loss scenarios) — may return a negative ROI, check if supported
- Service downtime on Railway hosting — returns 503 or connection timeout

## Output

Returns a JSON object with two fields: 'roi' (a decimal ratio, e.g. 1.5 meaning 150% return) and 'percentage' (the ROI expressed as a percentage, e.g. 150). Both represent how much return was achieved relative to the cost.
