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-two-input-scenario-grid-9a567a70 -d '<json body>'
```

Example prompt: Run a return rate scenario grid with a baseline of 100 sold units and 5 returned units, varying returned_units across [4, 5, 6] and sold_units across [90, 100, 110], so I can see how my return rate shifts across those combinations.

## When to prefer this

Choose this endpoint when you need a quick, offline two-dimensional sensitivity table for unit return rate without requiring live inventory data, platform fees, or order system access. It is ideal for pre-season planning, policy change modeling, or executive scenario briefings where you want to see how return rate responds to simultaneous changes in both sold and returned unit volumes.

## Known failure modes

- Invalid field_x or field_y enum values (must be 'returned_units' or 'sold_units')
- sold_units baseline set to zero causing division-by-zero in rate calculation
- values_x or values_y arrays exceed 10 items or are empty
- Numeric values outside allowed range (-1,000,000,000,000 to 1,000,000,000,000)
- Missing required baseline fields returned_units or sold_units

## How this service works

Unit return rate - Two-input scenario grid: Two-input scenario grid 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 two-input scenario grid deliverable.

## Output

A two-dimensional scenario grid (matrix) of computed unit return rates for every combination of the provided x-axis and y-axis input values, calculated locally from the supplied retail figures with no live data dependencies.
