## 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 unit-return-rate-base-100-rebase-report-18f769cd -d '<json body>'
```

Example prompt: Can you rebase my unit return rate data to a base-100 index, starting from the first period? Here are my rows: period 1 had 100 sold and 5 returned, period 2 had 120 sold and 7 returned, period 3 had 110 sold and 6 returned.

## When to prefer this

Choose this endpoint when you need to normalize unit return rate figures to a base-100 index for trend comparison or scenario modeling using your own retail data. It is a local computation service — ideal when you have raw sold/returned unit counts and want a rebased index without needing live inventory access, real-time platform data, or order execution. Prefer it over general analytics tools when you specifically need a base-100 rebase of return rate data in the retail context.

## Known failure modes

- Fewer than 2 rows supplied — minimum 2 rows required
- sold_units is 0 or missing — exclusiveMinimum constraint violated
- returned_units exceeds sold_units — logically invalid but may not be rejected
- base_index out of range — must be between 0 and 199 and within the supplied row count
- More than 200 rows supplied — maxItems constraint violated
- Non-numeric values in sold_units or returned_units fields

## How this service works

Unit return rate - Base-100 rebase report: Base-100 rebase report for Unit return rate. Supplied retail figures only. Local calculation and scenario analysis; no live inventory, account access, platform fee lookup or order execution. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded base-100 rebase report deliverable.

## Output

A base-100 rebased report for unit return rates across the supplied retail data rows. Each row's return rate is normalized relative to the designated base index row, expressed as an index value where the base period equals 100. Useful for trend comparison and scenario analysis without live inventory or platform data.
