# Inventory Position Sequential Input-Change Attribution

> Inventory Position Sequential Input-Change Attribution is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-23).

Performs waterfall (sequential input-change) attribution analysis on inventory position, showing how changes in on-hand, on-order, and backorder quantities each contribute to the overall position change.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-sequential-input-change-attribution-35bf33df -d '<json body>'
```

Example prompt: My inventory position changed — before I had 100 units on hand, 30 on order, and 10 backorders; now it's 110 on hand, 33 on order, and 11 backorders. Can you run a sequential input-change attribution to show how much each factor contributed to the overall position change?

## When to prefer this

Use this endpoint when you need to understand the relative contribution of individual inventory drivers (on-hand, on-order, backorders) to a total position change — especially for reporting, root-cause analysis, or scenario planning. It is purely a local calculation using supplied figures, so it does not require live inventory system access.

## Known failure modes

- Missing required fields in before or after objects returns a validation error
- Values outside the allowed range (0 to 1,000,000,000,000) are rejected
- Non-numeric values for quantity fields cause input schema errors
- Payment failure or insufficient USDC balance prevents execution

## How this service works

Inventory position - Sequential input-change attribution: Sequential input-change attribution 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 sequential input-change attribution deliverable.

## Output

A bounded sequential (waterfall) attribution deliverable showing how changes in each of the three inventory inputs — on_hand, on_order, and backorders — individually and cumulatively contribute to the overall change in inventory position between the before and after states.
