# Return Processing Cost Per Case – Weighted Mean

> Return Processing Cost Per Case – Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-21).

Computes the weighted mean of return processing cost per case across up to 200 retail return records, using labour, postage, and other cost inputs weighted by processed returns volume or custom weights.

## 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-weighted-mean-2549364b -d '<json body>'
```

Example prompt: I have 4 batches of return data: batch 1 had labour $100, postage $50, other $20 for 10 returns (weight 1); batch 2 had labour $110, postage $55, other $22 for 11 returns (weight 2); batch 3 matches batch 1 (weight 1); batch 4 matches batch 2 (weight 2) — can you calculate the weighted mean return processing cost per case across all of these?

## When to prefer this

Choose this endpoint when you need a single weighted aggregate benchmark for return processing cost per case from supplied retail data — especially when records represent different volumes (e.g. warehouses, channels, time periods) and you want volume-adjusted averaging. It is purpose-built for retail reverse logistics cost analytics and returns a single bounded weighted mean rather than raw data, rankings, or scenario comparisons. Use sibling endpoints for threshold classification, scenario comparison, or ranking instead.

## Known failure modes

- Fewer than 2 rows provided — minimum 2 records required
- More than 200 rows provided — exceeds maximum record limit
- processed_returns value is zero or negative — exclusiveMinimum constraint violated
- Weights array length does not match rows array length — mismatch error
- Non-numeric values in cost or weight fields — schema validation failure
- Extremely large cost or weight values approaching the 1e12 maximum may cause precision issues

## How this service works

Return processing cost per case - Weighted result mean: Weighted result mean 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 weighted result mean report.

## Output

A single weighted mean value representing the average return processing cost per case across all submitted records, computed by weighting each record's total cost per case (labour + postage + other costs divided by processed returns) according to the provided or default weights.
