## 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 net-merchandise-sales-local-finite-change-elasticity-calculator-6a71b2a0 -d '<json body>'
```

Example prompt: Calculate the local finite-change elasticity of net merchandise sales with respect to discounts, using a baseline of gross_merchandise_sales=10000, discounts=500, and returns=300, with a step size of 1%.

## When to prefer this

Choose this endpoint when you need a quick, local sensitivity or elasticity estimate for net merchandise sales using only supplied retail figures — no live platform data, inventory, or order execution is required. It is ideal for scenario planning and what-if analysis around discounts, returns, or gross sales changes in a retail context.

## Known failure modes

- Invalid field enum value — must be one of gross_merchandise_sales, discounts, or returns
- Baseline values out of range (negative or exceeding 1e12) cause validation errors
- step_percent outside 0.01–10 range returns a validation error
- Missing required baseline fields (gross_merchandise_sales, discounts, returns) causes schema rejection
- Payment not included or insufficient USDC balance results in 402 Payment Required

## How this service works

Net merchandise sales - Local finite-change elasticity: Local finite-change elasticity for Net merchandise sales. 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 net merchandise sales with respect to the selected input field, computed from the supplied baseline figures and step percentage. The result quantifies how much net merchandise sales change proportionally for a small finite perturbation in the chosen variable, enabling scenario planning and sensitivity analysis.
