# Order-line Picking Rate – Adjacent Period Changes

> Order-line Picking Rate – 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 2026-10-18).

Computes adjacent period changes in order-line picking rate (order lines picked per labour hour) across up to 200 supplied retail data rows.

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 order-line-picking-rate-adjacent-period-changes-67578a93 -d '<json body>'
```

Example prompt: Can you calculate the adjacent period changes in our order-line picking rate for these four shifts: first shift 480 lines in 8 hours, second shift 528 lines in 8.8 hours, third shift 480 lines in 8 hours, fourth shift 528 lines in 8.8 hours?

## When to prefer this

Choose this endpoint when you have raw retail order-picking data (lines picked and labour hours) for multiple consecutive periods and need to quantify how the picking rate is changing from one period to the next. It is purpose-built for retail warehouse productivity analysis with adjacent period comparison, not for live rate feeds, order execution, or platform-integrated WMS data.

## Known failure modes

- Fewer than 2 rows supplied — minimum array length not met
- Non-positive labour_hours value — exclusiveMinimum of 0 required
- More than 200 rows submitted — maxItems limit exceeded
- Negative picked_order_lines value — minimum 0 required
- Malformed row objects with extra or missing required fields

## How this service works

Order-line picking rate - Adjacent period changes: Adjacent period changes for Order-line picking rate. 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

Returns a bounded report of adjacent period changes in order-line picking rate (picked order lines divided by labour hours) for each consecutive pair of input rows, showing the calculated rate per period and the delta between adjacent periods, for up to 200 supplied retail records.
