# Case-pack Order Rounding – Sequential Input-Change Attribution

> Case-pack Order Rounding – 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 2026-10-14).

Performs waterfall/sequential input-change attribution analysis for case-pack order rounding, showing how changes in required_units or case_units between two states drive rounding differences.

## 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 case-pack-order-rounding-sequential-input-change-attribution-f7ed98c4 -d '<json body>'
```

Example prompt: Run a sequential input-change attribution for my case-pack rounding: before, I needed 25 units with a case size of 12; after, I need 28 units with a case size of 13 — show me which input change drove the rounding difference.

## When to prefer this

Use this endpoint when you need to understand *why* a case-pack rounded order quantity changed between two states, attributing the delta sequentially to individual input changes. Prefer it over the before/after comparison endpoint when you want a step-by-step waterfall breakdown rather than just a side-by-side diff.

## Known failure modes

- case_units must be at least 1 — zero or negative values will be rejected
- required_units or case_units exceeding 1,000,000 will fail validation
- missing required_units or case_units in either before or after object returns a validation error
- additional properties in the before/after objects are not allowed and will cause rejection

## How this service works

Case-pack order rounding - Sequential input-change attribution: Sequential input-change attribution for Case-pack order rounding. Supplied retail figures only, up to 200 records. No platform access, live rates or order execution. One of 25 new profiles across 20 shared operations in this industry. 0.01 USDC includes one bounded sequential input-change attribution report.

## Output

A bounded sequential input-change attribution report (up to 200 records) that decomposes the rounding difference between the before and after case-pack states, attributing the impact step-by-step to changes in required_units and case_units.
