# Return Processing Cost Per Case – Base-100 Rebase Report

> Return Processing Cost Per Case – Base-100 Rebase Report is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Rebases retail return processing cost-per-case figures to a base-100 index, normalizing labour, postage, and other costs across up to 200 data rows.

## 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-base-100-rebase-report-691d3e3d -d '<json body>'
```

Example prompt: Can you rebase our return processing cost data to a base-100 index using row 0 as the baseline? We have 4 periods: labour costs of 100, 110, 100, 110; postage costs of 50, 55, 50, 55; other costs of 20, 22, 20, 22; and processed returns of 10, 11, 10, 11.

## When to prefer this

Choose this endpoint when you need to normalize retail return processing cost-per-case figures to a base-100 index for trend analysis, benchmarking, or reporting — particularly when you have raw labour, postage, and other cost breakdowns alongside processed return volumes across multiple time periods or locations. It is purpose-built for retail return logistics cost indexing rather than general statistical normalization.

## Known failure modes

- processed_returns must be greater than 0 — zero-volume rows will fail validation
- base_index must be within the range of supplied rows (0 to rows.length-1); out-of-range values return an error
- Fewer than 2 rows supplied — minimum of 2 rows required
- Exceeding 200 rows triggers a maxItems validation error
- Missing required fields (labour_cost, postage_cost, other_cost, processed_returns) in any row causes a schema rejection
- Negative cost values are rejected (minimum: 0)

## How this service works

Return processing cost per case - Base-100 rebase report: Base-100 rebase report 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 base-100 rebase report report.

## Output

A base-100 rebase report where each row's return processing cost per case (derived from labour, postage, and other costs divided by processed returns) is expressed as an index relative to the designated baseline row (base_index). Returns up to 200 indexed records from the supplied retail figures.
