# Order-line Picking Rate – Local Finite-Change Elasticity

> Order-line Picking Rate – Local Finite-Change Elasticity 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 a bounded local finite-change elasticity report for order-line picking rate given retail baseline figures and a step percentage.

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-local-finite-change-elasticity-30b8436e -d '<json body>'
```

Example prompt: Using a baseline of 480 picked order lines and 8 labour hours, calculate the local finite-change elasticity of picked_order_lines with a 1% step — I want to see how sensitive my picking rate is to small labour changes.

## When to prefer this

Choose this endpoint when you need a quick, low-cost local finite-change elasticity estimate for a retail order-line picking rate around a specific operating baseline, and you already have your own picked order lines and labour hours figures. It is not a substitute for live rate feeds, order execution systems, or full demand-elasticity platforms — use it for bounded sensitivity analysis of warehouse picking productivity.

## Known failure modes

- Invalid or missing baseline values (picked_order_lines or labour_hours must be positive numbers)
- step_percent outside allowed range of 0.01–10 causes validation error
- Field enum value not one of 'picked_order_lines' or 'labour_hours' causes rejection
- Exceeding 200-record limit may result in truncation or error
- Payment of 0.01 USDC not confirmed leads to 402 Payment Required response

## How this service works

Order-line picking rate - Local finite-change elasticity: Local finite-change elasticity 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 local finite-change elasticity report.

## Output

Returns a bounded local finite-change elasticity value (and supporting report) indicating how much the order-line picking rate responds to a small percentage change in the specified field (picked_order_lines or labour_hours), based on the provided retail baseline figures. Up to 200 records; no live platform data or order execution included.
