## 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 target-replenishment-quantity-target-gap-calculation-cfc6a1b1 -d '<json body>'
```

Example prompt: I have a target of 200 units and my current inventory position is 120 units — can you calculate the replenishment gap I need to close?

## When to prefer this

Use this endpoint when you need a fast, local computation of the replenishment gap between a target stock level and current inventory position for retail planning or scenario analysis. It is ideal for lightweight, offline-style gap calculations where no live inventory system, account access, or order execution is needed. Prefer it over full inventory management APIs when you only need a single bounded calculation at minimal cost ($0.01 USDC).

## Known failure modes

- Missing required fields (target_units or inventory_position) returns a validation error
- Values outside allowed numeric range (target_units > 1,000,000,000,000 or inventory_position outside ±1,000,000,000,000) are rejected
- Non-numeric inputs for numeric fields cause schema validation failures
- Payment failure (insufficient USDC balance or x402 protocol error) blocks the request
