## 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 unit-return-rate-target-gap-calculator-eef13c20 -d '<json body>'
```

Example prompt: We sold 2,500 units last month and had 180 returns — calculate the gap between our actual unit return rate and our target of 5%.

## When to prefer this

Choose this endpoint when you need a quick, local computation of the gap between an observed retail unit return rate and a specified target, using only your own supplied figures — no live inventory, platform integration, or external data access required. Ideal for scenario modeling, KPI dashboards, and performance tracking against goals.

## Known failure modes

- sold_units must be greater than 0 (exclusiveMinimum enforced) — passing 0 will fail validation
- returned_units exceeding sold_units may produce a return rate above 100% — logically valid but may be flagged
- target value outside numeric bounds causes rejection
- missing required fields (sold_units or returned_units) returns a validation error
- network or payment processing failure returns no result
