## 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-local-finite-change-elasticity-dd6fbc59 -d '<json body>'
```

Example prompt: Can you calculate the local finite-change elasticity of target replenishment quantity using a baseline of 200 target units and 120 inventory position, stepping target_units by 1%?

## When to prefer this

Choose this endpoint when you need a fast, local, bounded sensitivity or elasticity estimate for retail replenishment target quantities — particularly when you have concrete baseline figures for target_units and inventory_position and want to understand marginal responsiveness to small perturbations. Prefer this over general-purpose statistical tools when you need a pre-packaged, low-cost ($0.01 USDC) elasticity computation without needing live inventory system access, platform fee lookups, or order execution.

## Known failure modes

- Invalid field value (must be 'target_units' or 'inventory_position') returns validation error
- step_percent outside range 0.01–10 returns schema validation error
- Baseline values exceeding maximum bounds (1e12) are rejected
- Missing required baseline properties cause request failure
- Network or payment processing failure returns 402 or 5xx error

## How this service works

Target replenishment quantity - Local finite-change elasticity: Local finite-change elasticity for Target replenishment quantity. 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 local finite-change elasticity deliverable.

## Output

Returns a bounded local finite-change elasticity value for the target replenishment quantity field, reflecting how the metric responds to a small percentage-step perturbation from the supplied baseline. Output is a numeric elasticity deliverable suitable for scenario analysis and retail replenishment planning; no live inventory data or order execution is included.
