# Order-line Picking Rate – Sequential Input-Change Attribution

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

Performs waterfall (sequential input-change) attribution analysis on order-line picking rate, isolating the individual contribution of each input change (picked order lines and labour hours) to the overall rate shift between two scenarios.

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-sequential-input-change-attribution-b4cdc6f9 -d '<json body>'
```

Example prompt: Run a sequential input-change attribution on our order-line picking rate: before we had 480 picked order lines and 8 labour hours, and after we had 528 picked order lines and 8.8 labour hours — show me how much each input change contributed to the rate shift.

## When to prefer this

Choose this endpoint when you need to explain *why* an order-line picking rate changed between two periods by attributing the delta to each input in sequence — particularly useful for operations reporting, root cause analysis, and communicating productivity shifts to stakeholders. Prefer it over a simple before/after comparison when you need to understand the isolated contribution of picked order lines vs labour hours separately, not just the aggregate change.

## Known failure modes

- labour_hours of 0 or negative will be rejected (exclusiveMinimum: 0)
- missing required fields (picked_order_lines or labour_hours in either before or after object) returns validation error
- non-numeric or out-of-range values (above 1e12) cause schema rejection
- payment failure or insufficient USDC balance blocks execution

## How this service works

Order-line picking rate - Sequential input-change attribution: Sequential input-change attribution 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 sequential input-change attribution report.

## Output

A bounded sequential input-change attribution report showing: the baseline order-line picking rate, the final picking rate, and a step-by-step waterfall decomposition isolating how much each input change (first picked_order_lines, then labour_hours, in sequence) contributed to the overall rate delta.
