# Return Processing Cost Per Case – Distribution Histogram

> Return Processing Cost Per Case – Distribution Histogram is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-19).

Computes a distribution histogram of return processing cost per case from supplied retail cost and volume data, grouped into configurable bins.

## 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 return-processing-cost-per-case-distribution-histogram-27284d2f -d '<json body>'
```

Example prompt: Using our retail returns data — labour cost $120, postage $60, other costs $25, with 15 processed returns per period — can you generate a distribution histogram for return processing cost per case using 8 bins?

## When to prefer this

Choose this endpoint when you need a statistical frequency distribution of return processing cost per case from your own supplied retail data, with configurable bin granularity, and do not need live platform data, order execution, or external rate lookups. Ideal for offline batch analysis of returns cost efficiency.

## Known failure modes

- Fewer than 2 rows supplied — minimum data requirement not met
- processed_returns value of zero causes division error — field requires exclusiveMinimum > 0
- More than 200 rows submitted — exceeds maximum item limit
- bins value outside 1–30 range rejected
- Malformed row objects missing required cost or volume fields

## How this service works

Return processing cost per case - Distribution histogram: Distribution histogram for Return processing cost per case. 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 distribution histogram report.

## Output

A bounded distribution histogram report showing how return processing cost per case (calculated as total costs divided by processed returns) is distributed across the specified number of bins, covering frequency counts and bin boundaries for up to 200 supplied retail records.
