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 aligned-shelf-packing-capacity-adjacent-period-changes-758c237a -d '<json body>'
```

Example prompt: Calculate the adjacent period change in shelf packing capacity for two scenarios: first a shelf that's 100 wide, 60 tall, and 40 deep holding items 20 wide, 15 tall, and 10 deep; then the same shelf scaled up 10% to 110x66x44 with items 22x16.5x11 — show me how capacity changed between the two periods.

## When to prefer this

Choose this endpoint when you need to quantify how retail shelf packing capacity has changed between two adjacent time periods based on physical shelf and item dimensions. It is ideal for planogram analysis, product redesign impact assessment, and space efficiency tracking in retail environments where you have concrete dimension data for both periods.

## Known failure modes

- Missing required dimension fields (shelf_width, shelf_height, shelf_depth, item_width, item_height, item_depth) returns a validation error
- Fewer than 2 rows submitted returns an error (minItems: 2 required)
- More than 200 rows submitted is rejected (maxItems: 200)
- Zero or negative dimension values are rejected (exclusiveMinimum: 0)
- Payment failure or insufficient USDC balance prevents execution

## How this service works

Aligned shelf packing capacity - Adjacent period changes: Adjacent period changes for Aligned shelf packing capacity. 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 adjacent period changes report.

## Output

A bounded report showing the computed adjacent-period change in aligned shelf packing capacity for each pair of input rows (up to 200 records), including the calculated capacity values per period and the delta between them.
