# Save Files Analytics — Trailing Mean Series + Keyed Dataset Comparison

> Save Files Analytics — 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 2026-11-03).

Computes a trailing mean time series and a keyed dataset comparison for up to 200 save-file records, reporting on save_kb or write_ms metrics across game areas.

## 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 save-files-analytics-trailing-mean-series-keyed-dataset-comparison-0e9cb0d9 -d '<json body>'
```

Example prompt: Can you run a trailing mean analysis and dataset comparison on my save file records? I have two sets of up to 50 rows each with fields row_id, game_area, date, save_kb, and write_ms — use a window of 3 and analyze the save_kb field.

## When to prefer this

Choose this endpoint when you need both a rolling/trailing mean time series and a side-by-side keyed comparison of two save-file datasets in a single call, specifically for game save metrics (save_kb, write_ms) segmented by game_area. It is well-suited for game developers or QA pipelines that want statistical trend analysis and dataset divergence detection without setting up their own analytics infrastructure. Not appropriate for real-time monitoring, prediction, or datasets exceeding 200 rows.

## Known failure modes

- Missing required row fields (row_id, game_area, date, save_kb, write_ms) causes validation error
- More than 200 rows submitted results in rejection
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- Invalid field enum value (not save_kb or write_ms) causes rejection
- Empty rows array causes error
- Payment not included or insufficient USDC causes 402 response

## How this service works

Save files — Trailing mean series + Keyed dataset comparison: Trailing mean series + Keyed dataset comparison for supplied save files records (save_kb, write_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 analytical reports: (1) a trailing mean time series showing the rolling average of the selected metric (save_kb or write_ms) over the supplied date-ordered rows, and (2) a keyed dataset comparison highlighting differences between the primary and secondary datasets grouped by game_area. Up to 200 rows are supported per dataset.
