# Inventory Sell-Through Local Finite-Change Elasticity

> Inventory Sell-Through 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 inventory sell-through rate, given a baseline of sold and ending units plus a step percentage, using only supplied figures.

## 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-sell-through-local-finite-change-elasticity-32a7267a -d '<json body>'
```

Example prompt: Calculate the local finite-change elasticity for sell-through using a baseline of 80 sold units and 20 ending units, varying the sold_units field with a 1% step — I want to see how sensitive the sell-through rate is to that small change.

## When to prefer this

Use this endpoint when you need a quick, local finite-change elasticity computation for sell-through rate from supplied retail figures, with no need for live inventory data or platform integration. It is ideal for scenario analysis and sensitivity testing around a specific baseline without side effects or account access.

## Known failure modes

- Invalid field enum value (not 'sold_units' or 'ending_units') returns validation error
- step_percent outside range 0.01–10 is rejected
- sold_units or ending_units outside 0–1,000,000,000,000 are rejected
- Missing required baseline fields returns schema validation error
- Zero total units (sold + ending = 0) may produce undefined elasticity or division-by-zero result

## How this service works

Inventory sell-through - Local finite-change elasticity: Local finite-change elasticity for Inventory sell-through. 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 inventory sell-through metric, computed from the supplied baseline (sold_units and ending_units) and the specified step_percent applied to the chosen field. No live inventory, account, or platform data is involved — results are deterministic given the inputs.
