# Unrounded Billable Parcel Weight - Adjacent Period Changes

> Unrounded Billable Parcel Weight - Adjacent Period Changes is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Computes adjacent period changes (differences and percentage shifts) for unrounded billable parcel weight derived from actual and dimensional weight inputs, for retail shipping scenario analysis.

## 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-adjacent-period-changes-6689de9c -d '<json body>'
```

Example prompt: Can you calculate the adjacent period changes in unrounded billable parcel weight for these four shipments — first period actual weights 6 and 6.6 lbs with dimensional weights 4 and 4.4, then same pattern repeating in the next period?

## When to prefer this

Choose this endpoint when you need to quantify how unrounded billable parcel weight has shifted between adjacent periods using retail actual and dimensional weight data, especially for scenario modeling, cost variance analysis, or audit preparation. It is a local computation with no live carrier, inventory, or account dependencies, making it fast and deterministic. Prefer alternatives if you need live carrier rate lookups, rounded weight figures, or non-adjacent (e.g. year-over-year) period comparisons.

## Known failure modes

- Fewer than 2 rows supplied — minItems constraint violated, request rejected
- Row missing required actual_weight or dimensional_weight field — validation error
- Weight values exceed maximum (1,000,000,000,000) — out-of-range error
- More than 200 rows submitted — maxItems constraint exceeded
- Non-numeric weight values supplied — schema type error

## How this service works

Unrounded billable parcel weight - Adjacent period changes: Adjacent period changes 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 adjacent period changes deliverable.

## Output

Returns adjacent period changes for unrounded billable parcel weight — specifically the differences or shifts between consecutive period rows computed from actual and dimensional weight inputs. Results are local calculations based purely on supplied figures, not connected to live carrier rates or account data.
