## 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 parking-utilization-secondary-measure-weighted-mean-09344b37 -d '<json body>'
```

Example prompt: Can you calculate the weighted mean of occupied_spaces for my parking zones? I have data for zones group-a and group-b over the past week — here are rows with date, zone, row_id, occupied_spaces, and available_spaces for about 20 records.

## When to prefer this

Use this endpoint when you need a local, bounded descriptive statistic (weighted mean) on parking utilization data you already have in hand, without needing enrichment, forecasting, or external data lookup. It is ideal for summarizing batch records of occupied and available parking spaces across zones and dates in a single low-cost call.

## Known failure modes

- Fewer than 1 row submitted — returns validation error
- More than 200 rows submitted — exceeds maxItems limit, rejected
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Missing required fields (row_id, zone, date, occupied_spaces, available_spaces) — rejected
- All values null for the target field — may return null or error result
- Invalid field enum value — schema validation error

## How this service works

Parking utilization - Secondary-measure weighted mean: Secondary-measure weighted mean for Parking utilization. Up to 200 supplied typed records. Local descriptive analytics; no enrichment or forecast. One of 25 new profiles across 20 shared operations in this industry. 0.01 USDC includes one bounded secondary-measure weighted mean report.

## Output

Returns a bounded descriptive analytics report containing the secondary-measure weighted mean of the selected field (occupied_spaces or available_spaces) computed across the submitted parking utilization records, segmented by zone and date as applicable.
