# Localization Coverage — Trailing Mean Series + Keyed Dataset Comparison

> Localization Coverage — Trailing Mean Series + 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).

Computes a trailing mean time series and a keyed dataset comparison for localization coverage records (source_strings, translated_strings) across up to 200 rows.

## 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 localization-coverage-trailing-mean-series-keyed-dataset-comparison-86f52004 -d '<json body>'
```

Example prompt: Can you run a trailing mean series and keyed dataset comparison on my game localization coverage data? I have two sets of up to 200 rows each with game_area, date, source_strings, and translated_strings — use 'translated_strings' as the field, and compare my current sprint data against last sprint's baseline.

## When to prefer this

Choose this endpoint when you need both a rolling/trailing mean time series and a side-by-side keyed comparison for localization coverage data (source_strings and translated_strings) in a single call. It is purpose-built for game localization analytics and covers two reports in one request at low cost, making it ideal for sprint reviews or QA reporting workflows where no external data lookup or prediction is needed.

## Known failure modes

- Missing required fields (row_id, game_area, date, source_strings, translated_strings) causes validation error
- Exceeding 200 rows in either dataset returns an error
- Invalid date format (non YYYY-MM-DD) causes rejection
- Null values in numeric fields may affect trailing mean computation
- Invalid 'field' enum value causes schema validation failure

## How this service works

Localization coverage — Trailing mean series + Keyed dataset comparison: Trailing mean series + Keyed dataset comparison for supplied localization coverage records (source_strings, translated_strings). 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) a trailing mean time series computed over the selected field (source_strings or translated_strings) across the supplied rows, and (2) a keyed dataset comparison between the primary rows dataset and the secondary 'other' dataset, grouped by game_area. Results are computed locally with no external lookups.
