> Retail Replenishment Quantity - 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 2026-10-18).

Performs sequential (waterfall) attribution analysis showing how changes in target units and inventory position drive the replenishment quantity outcome.

## 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 retail-replenishment-quantity-sequential-input-change-attribution-43513f6b -d '<json body>'
```

Example prompt: My target units went from 200 to 220 and my inventory position went from 120 to 132 — can you run a sequential waterfall attribution to show me how much each of those input changes contributed to the shift in my replenishment quantity?

## When to prefer this

Choose this endpoint when you need to decompose — in sequential/waterfall order — exactly how changes in target stock levels and inventory position each contributed to a shift in replenishment quantity. It is ideal for scenario analysis, root-cause investigation of order quantity changes, and retail planning workflows where you supply your own figures and want a local, offline-style calculation with no dependency on live inventory systems or platform integrations.

## Known failure modes

- Missing required before or after fields returns a validation error
- Non-numeric values for target_units or inventory_position cause schema rejection
- inventory_position below -1,000,000,000,000 or target_units above 1,000,000,000,000 exceed schema bounds
- Identical before and after values may return zero-attribution result
- Payment not fulfilled (x402) results in 402 response and no computation

## How this service works

Target replenishment quantity - Sequential input-change attribution: Sequential input-change attribution 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 sequential input-change attribution deliverable.

## Output

Returns a sequential (waterfall) attribution result quantifying how much each input change — target_units delta and inventory_position delta — individually contributed to the overall change in the computed replenishment quantity, based purely on the supplied before/after retail figures with no live data access.
