# Inventory Position Local Finite-Change Elasticity

> Inventory Position Local Finite-Change Elasticity is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Computes local finite-change elasticity for retail inventory position fields (on-hand, on-order, backorders) given a baseline and a step-percent perturbation.

## 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 inventory-position-local-finite-change-elasticity-ead3ef6c -d '<json body>'
```

Example prompt: Can you calculate the local finite-change elasticity for my inventory position, focusing on the on_hand field, with a baseline of 100 units on hand, 30 on order, and 10 backorders, using a 1% step?

## When to prefer this

Choose this endpoint when you need a quick, local, finite-difference sensitivity or elasticity estimate for retail inventory position metrics (on-hand, on-order, backorders) without requiring live inventory system access, real-time platform data, or order execution. It is ideal for offline scenario planning, sensitivity checks, and understanding how small percentage changes in one inventory dimension affect overall inventory position.

## Known failure modes

- Invalid field value outside enum (on_hand, on_order, backorders) returns validation error
- baseline quantities exceeding maximum limit (1,000,000,000,000) rejected
- step_percent below 0.01 or above 10 returns out-of-range error
- Missing required baseline sub-fields (on_hand, on_order, backorders) causes request failure
- Payment not included or insufficient USDC causes 402 Payment Required response

## How this service works

Inventory position - Local finite-change elasticity: Local finite-change elasticity for Inventory position. 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 the local finite-change elasticity value for the selected inventory position field (on_hand, on_order, or backorders), quantifying how the inventory position metric responds to a small percentage perturbation around the supplied baseline quantities. The result enables scenario analysis and sensitivity understanding without live inventory access.
