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 unit-return-rate-named-scenario-comparison-9f578e5b -d '<json body>'
```

Example prompt: Compare my unit return rate across two scenarios: my baseline is 500 sold units with 30 returned, then run a scenario called 'Holiday Season' with 800 sold and 60 returned, and another called 'Post-Promo Dip' with 400 sold and 45 returned.

## When to prefer this

Choose this endpoint when you need a quick, local what-if analysis on retail unit return rates across multiple named hypothetical scenarios without needing live inventory data, platform fee lookups, or order execution. Ideal for planning and reporting workflows where the user supplies their own figures and wants labeled scenario outputs they can directly compare.

## Known failure modes

- sold_units of 0 triggers exclusiveMinimum validation error
- Missing required label or overrides in a scenario causes schema rejection
- Scenarios array empty or exceeding 20 items fails validation
- Overrides object with no properties (minProperties:1 violation) returns error
- Non-numeric inputs for unit counts cause type errors

## How this service works

Unit return rate - Named scenario comparison: Named scenario comparison 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 named scenario comparison deliverable.

## Output

A structured comparison of unit return rates across the baseline and each named scenario, showing the calculated return rate (returned_units / sold_units) for each labeled configuration so the user can directly compare performance under different assumptions.
