# Case-Pack Order Rounding – Target Gap Calculator

> Case-Pack Order Rounding – Target Gap Calculator is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-13).

Calculates the target gap for case-pack order rounding given a target quantity and case/required unit counts, returning a bounded report for retail supply planning.

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 case-pack-order-rounding-target-gap-calculator-d35d3a0a -d '<json body>'
```

Example prompt: I need to order 25 units but they come in cases of 12 — can you calculate the target gap from my target of 25 using case-pack rounding so I know how many excess units I'll end up with?

## When to prefer this

Use this endpoint when you need a quick, inexpensive computation of the case-pack rounding gap for retail order planning — specifically when you have a known target quantity and a fixed case size and want to know the overage or shortfall after rounding. Prefer this over manual spreadsheet math or more complex inventory optimization APIs when the only question is the arithmetic delta from case-pack rounding for up to 200 records at a time.

## Known failure modes

- Required fields missing (required_units or case_units not provided) returns validation error
- case_units value of 0 or negative triggers minimum constraint violation
- required_units or case_units exceeding 1,000,000 returns out-of-range error
- Non-integer values for case_units or required_units fail schema validation
- Service unavailable or payment not processed returns 402 or 5xx error

## How this service works

Case-pack order rounding - Target gap calculation: Target gap calculation for Case-pack order rounding. 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 target gap calculation report.

## Output

A bounded target gap calculation report showing the numerical difference (gap) between the stated target quantity and the quantity resulting from rounding up to the nearest full case pack, given the required units and case size. Limited to supplied retail figures only; up to 200 records per call.
