# Unrounded Billable Parcel Weight — Sequential Input-Change Attribution

> Unrounded Billable Parcel Weight — 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).

Computes a sequential (waterfall) attribution analysis showing how changes in actual weight and dimensional weight each contribute to the change in unrounded billable parcel weight.

## 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 unrounded-billable-parcel-weight-sequential-input-change-attribution-34d860fc -d '<json body>'
```

Example prompt: My parcel's actual weight went from 6 lbs to 6.6 lbs and its dimensional weight went from 4 lbs to 4.4 lbs — can you run a sequential waterfall attribution to show me how much each of those changes contributed to the shift in unrounded billable weight?

## When to prefer this

Use this endpoint when you need to understand sequentially how specific changes in actual weight and dimensional weight each contributed to a change in unrounded billable parcel weight, particularly for scenario analysis, packaging optimization audits, or explaining shipping cost shifts. It is local computation only — not suitable if you need live carrier rates, account-level pricing, or order execution.

## Known failure modes

- Missing required 'before' or 'after' object fields returns a validation error
- Negative weight values rejected (minimum is 0)
- Extremely large weight values near the 1,000,000,000,000 maximum may produce edge-case results
- No live carrier data or account info available — retail figures only
- Service unavailable if payment of 0.01 USDC is not completed via x402 protocol

## How this service works

Unrounded billable parcel weight - Sequential input-change attribution: Sequential input-change attribution for Unrounded billable parcel weight. 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 report showing how the change from the 'before' state (actual_weight, dimensional_weight) to the 'after' state breaks down into ordered contributions to the change in unrounded billable parcel weight — quantifying how much each input change drove the overall delta.
