# UI Screens — Category Frequencies + Daily Sum Series

> UI Screens — Category Frequencies + Daily Sum Series is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-02).

Analyzes UI screen records to produce category frequency distributions and daily sum time series for widget_count or render_ms fields.

## 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 ui-screens-category-frequencies-daily-sum-series-cbbd10c2 -d '<json body>'
```

Example prompt: Analyze my UI screen records and give me both the category frequency breakdown by game_area and the daily sum series for widget_count — I have up to 200 rows with fields row_id, game_area, date, widget_count, and render_ms.

## When to prefer this

Choose this endpoint when you need both a categorical frequency summary and a daily aggregated time series in a single call for UI screen telemetry data (widget_count or render_ms). It is ideal for game UI analytics where you have up to 200 rows of screen records with game_area, date, and numeric metric fields and want two bundled reports at minimal cost without external data dependencies.

## Known failure modes

- Rows array is empty or missing — minimum 1 row required
- More than 200 rows submitted — exceeds maxItems limit
- Date field does not match YYYY-MM-DD pattern — validation error
- Invalid field enum value — must be 'widget_count' or 'render_ms'
- row_id is missing or empty string — required field violation
- Numeric fields exceed allowed range bounds — rejected

## How this service works

UI screens — Category frequencies + Daily sum series: Category frequencies + Daily sum series for supplied ui screens records (widget_count, render_ms). 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 independent analytical reports: (1) category frequencies showing how often each game_area value appears across the supplied rows, and (2) a daily sum time series showing the total of the selected numeric field (widget_count or render_ms) aggregated by date — both computed locally on the supplied data without external lookups.
