# Parking Utilization - Explicit Missing-Value Fill

> Parking Utilization - Explicit Missing-Value Fill is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-17).

Fills missing numeric values (occupied_spaces or available_spaces) in parking utilization records using zero, mean, or median imputation across up to 200 rows.

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 parking-utilization-explicit-missing-value-fill-d3412f09 -d '<json body>'
```

Example prompt: I have parking records for zones A and B across several dates, but some occupied_spaces values are null — can you fill those missing values using the median method across up to 200 rows?

## When to prefer this

Choose this endpoint when you have tabular parking utilization records with missing occupied_spaces or available_spaces values and need a fast, bounded imputation using simple statistical methods (zero, mean, or median). It is ideal for data cleaning before dashboards, reports, or further analytics pipelines, and supports up to 200 records per call at very low cost. It does not perform forecasting, enrichment, or external lookups.

## Known failure modes

- Empty rows array or exceeding 200 items returns a validation error
- Invalid date format (not YYYY-MM-DD) causes schema rejection
- Unknown field name outside enum causes bad request
- All values already present with no nulls returns unchanged data
- Extremely large numeric outliers may skew mean imputation

## How this service works

Parking utilization - Explicit missing-value fill: Explicit missing-value fill 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 explicit missing-value fill report.

## Output

A bounded report containing the original parking utilization records with missing values in the specified field (occupied_spaces or available_spaces) filled using the chosen method (zero, mean, or median), limited to up to 200 rows. No forecasting or external enrichment is applied — purely local descriptive imputation.
