## 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-fill-rate-ordered-trend-analysis-f73d4834 -d '<json body>'
```

Example prompt: Can you run an ordered trend analysis on my unit fill rate? Here are my data points: period 1 had 100 ordered and 95 fulfilled, period 2 had 110 ordered and 104 fulfilled, period 3 had 120 ordered and 108 fulfilled, period 4 had 115 ordered and 112 fulfilled.

## When to prefer this

Choose this endpoint when you have a sequential series of retail ordered-vs-fulfilled unit pairs and need to understand the directional trend in fill rate over time. It is ideal for local, offline-style calculation without needing live inventory access, and when you want a bounded, reproducible trend deliverable for 2–200 periods of supplied retail data.

## Known failure modes

- Fewer than 2 rows supplied — minimum 2 data points required
- ordered_units value of 0 or missing (exclusiveMinimum:0 enforced)
- fulfilled_units exceeds ordered_units by extreme margin — may produce fill rate >1
- More than 200 rows supplied — maxItems limit exceeded
- Non-numeric values in ordered_units or fulfilled_units fields
- Malformed row objects missing required fields

## How this service works

Unit fill rate - Ordered trend analysis: Ordered trend analysis for Unit fill 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 ordered trend analysis deliverable.

## Output

Returns a bounded ordered trend analysis deliverable summarizing the directional trend in unit fill rate (fulfilled/ordered) across the supplied rows, including trend direction, magnitude, and relevant statistical indicators — all computed locally from the supplied data with no live inventory or account access.
