# UV Layouts Analytics — Equal-Width Histogram + Secondary-Measure Weighted Mean

> UV Layouts Analytics — Equal-Width Histogram + Secondary-Measure Weighted Mean 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 an equal-width histogram and a secondary-measure weighted mean for UV layout records (island_count, occupied_percent) supplied by the caller.

## 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-analytics-equal-width-histogram-secondary-measure-weighted-93a512fd -d '<json body>'
```

Example prompt: Can you run a histogram and weighted mean analysis on my UV layout data? I have 4 rows — row-1 (group-a, 2026-10-01, island_count=10, occupied_percent=1), row-2 (group-b, 2026-10-02, island_count=20, occupied_percent=2), row-3 (group-a, 2026-10-03, island_count=15, occupied_percent=3), row-4 (group-b, 2026-10-04, island_count=30, occupied_percent=4) — use 5 bins and analyze the island_count field.

## When to prefer this

Choose this endpoint when you have UV layout tabular data with island_count and occupied_percent columns and need both a frequency distribution (histogram) and a weighted mean statistic in a single API call. It is purpose-built for UV mapping analytics rather than general-purpose statistics APIs, and covers up to 200 rows at a low flat rate. Prefer it over generic stats APIs when your data is already structured as UV layout records with asset_group and date fields.

## Known failure modes

- More than 200 rows submitted — request rejected or truncated
- Missing required fields (row_id, island_count, or occupied_percent) on any row — validation error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Bins value outside 1–30 range — rejected
- All values for the primary field are null — cannot compute histogram
- Payment not included or insufficient USDC — x402 payment required error

## How this service works

UV layouts — Equal-width histogram + Secondary-measure weighted mean: Equal-width histogram + Secondary-measure weighted mean 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 analytical reports: (1) an equal-width histogram showing bin ranges and frequencies for the chosen primary field (island_count or occupied_percent), and (2) a secondary-measure weighted mean where the unchosen field is averaged using the primary field as weights — both computed locally over up to 200 supplied UV layout rows.
