# Reorder Point Sequential Input-Change Attribution

> Reorder Point 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 2026-10-19).

Performs waterfall/sequential attribution analysis showing how changes in lead days, safety units, and average daily demand each contribute to a change in reorder point

## 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 reorder-point-sequential-input-change-attribution-a4e3aa4f -d '<json body>'
```

Example prompt: My reorder point inputs changed — before it was 5 units/day demand, 10 lead days, and 20 safety units, and now it's 5.5 units/day, 11 lead days, and 22 safety units. Can you do a sequential waterfall attribution to show how much each change contributed to the shift in reorder point?

## When to prefer this

Choose this endpoint when you need to explain why a reorder point changed by decomposing the contribution of each input variable sequentially — ideal for audits, ops reporting, or scenario comparisons. Use it over a simple reorder point calculator when you have two states (before/after) and need to attribute the delta to specific drivers rather than just compute a single value.

## Known failure modes

- Missing required fields in before or after objects returns a validation error
- Negative or non-numeric values for lead_days, safety_units, or average_daily_demand are rejected
- Identical before and after inputs yield zero attribution across all variables
- Extremely large values (near 1,000,000,000,000) may produce very large output numbers but are accepted

## How this service works

Reorder point - Sequential input-change attribution: Sequential input-change attribution for Reorder point. 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 sequential (waterfall) attribution breakdown showing how each individual input change — lead days, safety units, and average daily demand — contributed to the overall change in reorder point between the before and after states, with each variable's marginal contribution quantified in order.
