## 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 gross-margin-return-on-inventory-gmroi-target-gap-calculator-031051f3 -d '<json body>'
```

Example prompt: My store has a gross profit of $5,000 and average inventory cost of $2,500 — can you calculate the gap between my current GMROI and a target of 3.0?

## When to prefer this

Choose this endpoint when you need a fast, local GMROI target-gap computation using retail figures you already have — particularly for scenario analysis or benchmarking without needing live inventory data, platform integrations, or order execution. Best suited for retail analysts, buyers, or agents running inventory profitability checks programmatically at low cost.

## Known failure modes

- average_inventory_cost must be greater than zero (exclusive minimum enforced)
- values exceeding maximum bounds ($1 trillion) will be rejected
- missing required fields gross_profit or average_inventory_cost returns a validation error
- target value outside the allowed range triggers an error

## How this service works

Gross margin return on inventory - Target gap calculation: Target gap calculation for Gross margin return on inventory. Supplied retail figures only. Local calculation and scenario analysis; no live inventory, account access, platform fee lookup or order execution. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded target gap calculation deliverable.

## Output

Returns a bounded calculation showing the current GMROI (gross profit divided by average inventory cost), the user-supplied target GMROI, and the arithmetic gap between the two — enabling quick scenario analysis of inventory profitability performance without accessing live inventory systems.
