# UI Screens — String Normalisation + Keyed Dataset Comparison

> UI Screens — String Normalisation + Keyed Dataset Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-23).

Normalises strings and performs keyed dataset comparison on UI screen records (widget_count, render_ms) across two supplied datasets of up to 200 rows each.

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 ui-screens-string-normalisation-keyed-dataset-comparison-9fd040fb -d '<json body>'
```

Example prompt: Compare these two sets of UI screen records — both have rows with row_id, game_area, date, widget_count, and render_ms — normalise the strings and tell me where the keyed values differ between the two datasets.

## When to prefer this

Choose this endpoint when you need both string normalisation and keyed row-by-row comparison of two UI screen datasets (widget_count, render_ms) in a single low-cost call. It is ideal for QA workflows, A/B performance audits, or regression checks on game UI metrics where you supply the data locally and do not need live lookups, predictions, or external enrichment.

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Missing required fields (row_id, game_area, date, widget_count, render_ms) on any row — validation error
- Invalid date format (must match YYYY-MM-DD) — schema validation failure
- Empty rows array (minItems:1 violated) — request rejected
- Payment not provided or insufficient — x402 payment required response

## How this service works

UI screens — String normalisation + Keyed dataset comparison: String normalisation + Keyed dataset comparison 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: one covering string normalisation of the supplied UI screen records and one providing a keyed dataset comparison between the two input arrays, covering the widget_count and render_ms fields across up to 200 rows per dataset. No external lookups or predictions are made; all analysis is performed locally on the supplied data.
