## 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-two-measure-correlation-e67a3135 -d '<json body>'
```

Example prompt: Can you run a two-measure correlation analysis on my parking utilization data? I have up to 50 records with zone names like 'zone-A' and 'zone-B', dates in YYYY-MM-DD format, and columns for occupied_spaces and available_spaces — I want to know how strongly those two measures correlate.

## When to prefer this

Choose this endpoint when you have up to 200 structured parking utilization records and need a fast, local descriptive correlation between occupied spaces and available spaces, without requiring external data enrichment or predictive forecasting. Ideal for facility managers or analysts who want a bounded, single-purpose statistical result at minimal cost ($0.01 USDC).

## Known failure modes

- Fewer than 1 row submitted — request rejected
- More than 200 rows submitted — request rejected due to maxItems constraint
- Missing required fields (row_id, zone, date, occupied_spaces, available_spaces) cause validation errors
- Malformed date strings not matching YYYY-MM-DD pattern cause schema validation failure
- All null values for one measure prevents correlation computation
- Payment not provided or insufficient USDC — x402 payment required error

## How this service works

Parking utilization - Two-measure correlation: Two-measure correlation 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 two-measure correlation report.

## Output

A bounded two-measure correlation report quantifying the statistical relationship between occupied_spaces and available_spaces across the submitted parking zone records, including descriptive analytics such as correlation coefficient and summary statistics. No external enrichment or forecasting is included.
