# UV Layouts — Equal-Width Histogram + Explicit Missing-Value Fill

> UV Layouts — Equal-Width Histogram + 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).

Generates an equal-width histogram and fills missing values in UV layout records (island_count, occupied_percent) for up to 200 rows using local analytical engines.

## 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-equal-width-histogram-explicit-missing-value-fill-f33fe96e -d '<json body>'
```

Example prompt: Can you run a histogram analysis on my UV layout data — 4 bins, analyzing the island_count field — and fill any missing values using the median? Here are my records: row-1 (group-a, 2026-10-01, island_count=10, occupied_percent=55), row-2 (group-b, 2026-10-02, island_count=null, occupied_percent=60), row-3 (group-a, 2026-10-03, island_count=15, occupied_percent=null).

## When to prefer this

Choose this endpoint when you have UV layout tabular data with island_count or occupied_percent metrics and need both a frequency distribution (histogram) and missing-value imputation in a single call. It is purpose-built for 3D/graphics asset workflows where UV coverage and island metrics need statistical summarization. Prefer this over general-purpose analytics tools when the dataset is small (≤200 rows), you want a fixed-cost ($0.01 USDC) computation, and you need both reports together without setting up external data pipelines.

## Known failure modes

- More than 200 rows submitted — request rejected or truncated
- Invalid date format (not YYYY-MM-DD) causes row validation failure
- Unknown fill method (not zero/mean/median) causes parameter rejection
- bins value outside 1–30 range causes schema validation error
- All values for the selected field are null — mean/median imputation cannot be computed
- Missing required fields (row_id) in any row causes rejection

## How this service works

UV layouts — Equal-width histogram + Explicit missing-value fill: Equal-width histogram + 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: (1) an equal-width histogram showing bin ranges and row counts for the selected numeric field (island_count or occupied_percent), and (2) the dataset with missing values in that field explicitly filled using the chosen method (zero, mean, or median). Both reports cover up to 200 input rows and are computed locally without external lookups.
