# Parcel Space Utilization Before and After Comparison

> Parcel Space Utilization Before and After Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Computes a before-and-after comparison report for parcel space utilization efficiency, given retail goods volume and package internal volume for two time periods.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 parcel-space-utilization-before-and-after-comparison-58efbf6a -d '<json body>'
```

Example prompt: Compare our parcel space utilization before and after our packaging update — before, goods volume was 600 and package internal volume was 1000; after, goods volume is 660 and package internal volume is 1100. Give me the comparison report.

## When to prefer this

Choose this endpoint when you need a quick, cheap ($0.01 USDC) computed comparison of parcel space utilization efficiency across two discrete time points or operational states, using only supplied retail volume figures. Prefer this over general analytics platforms when you want a bounded, structured report without needing platform access, live rates, or order execution capabilities.

## Known failure modes

- package_internal_volume of zero is rejected (exclusiveMinimum: 0)
- missing required fields (goods_volume or package_internal_volume) in before or after objects returns validation error
- values exceeding maximum (1e12) may be rejected or produce unexpected results
- non-numeric inputs cause schema validation failure
- payment failure (insufficient USDC) results in no report returned

## How this service works

Parcel space utilization - Before and after comparison: Before and after comparison for Parcel space utilization. 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 before and after comparison report.

## Output

A bounded before-and-after comparison report (up to 200 records) showing parcel space utilization metrics for both the 'before' and 'after' states, including utilization ratios derived from goods volume and package internal volume, and the change between the two periods. Covers supplied retail figures only; no live rates, platform access, or order execution.
