# UV Layouts — Numeric Distribution + Explicit Missing-Value Fill

> UV Layouts — Numeric Distribution + 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 2026-10-27).

Computes numeric distribution statistics and fills missing values (island_count, occupied_percent) for up to 200 UV layout records using local analytical engines.

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 uv-layouts-numeric-distribution-explicit-missing-value-fill-939aeaa4 -d '<json body>'
```

Example prompt: I have up to 200 UV layout rows with island_count and occupied_percent fields — some have nulls. Can you run a numeric distribution report on island_count and fill the missing values using median imputation?

## When to prefer this

Choose this endpoint when you need both numeric distribution analysis AND missing-value imputation in a single call for UV layout records (island_count, occupied_percent) at low cost ($0.01 USDC for 2 reports on up to 200 rows). Prefer it over general-purpose analytics tools when your data is already in the UV layout schema format and you want a fast, offline, deterministic result with no external API calls or predictions.

## Known failure modes

- More than 200 rows submitted — request rejected or truncated
- Invalid date format (not YYYY-MM-DD) causes row rejection
- row_id missing or empty string triggers validation error
- Numeric values outside the allowed range (±1 trillion) may cause errors
- Unknown fill method enum value causes parameter error
- Empty rows array causes a validation failure

## How this service works

UV layouts — Numeric distribution + Explicit missing-value fill: Numeric distribution + Explicit missing-value fill for supplied uv layouts records (island_count, occupied_percent). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.

## Output

Returns two reports for the supplied UV layout rows: (1) a numeric distribution report for the specified field (island_count or occupied_percent), including statistical spread metrics, and (2) a missing-value fill report showing how null values in that field were replaced using the chosen method (zero, mean, or median). Results are computed locally with no external lookups. Covers up to 200 input rows per call.
