# Save Files Analyzer — Category Frequencies + Secondary-Measure Weighted Mean

> Save Files Analyzer — Category Frequencies + 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 2026-11-02).

Computes category frequencies and a secondary-measure weighted mean for save file records (save_kb, write_ms) across up to 200 rows using local analytical engines.

## 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-analyzer-category-frequencies-secondary-measure-weighted-e250b183 -d '<json body>'
```

Example prompt: Can you analyze my save file records and give me both a category frequency breakdown by game_area and the weighted mean of save_kb (weighted by write_ms)? Here are my rows: row-1 on 2026-10-01 in group-a with save_kb=10 and write_ms=1, row-2 on 2026-10-02 in group-b with save_kb=20 and write_ms=2, row-3 on 2026-10-03 in group-a with save_kb=15 and write_ms=3.

## When to prefer this

Choose this endpoint when you have game save file records with both a categorical dimension (game_area) and two numeric measurements (save_kb, write_ms), and you need both a frequency distribution of categories and a weighted mean statistic in a single low-cost call. Ideal for lightweight game analytics pipelines where no external data enrichment or live lookup is needed.

## Known failure modes

- Exceeding 200 rows returns an error or truncation
- Missing required fields (row_id, game_area, date, save_kb, write_ms) cause validation failure
- Invalid date format (not YYYY-MM-DD) rejected by schema
- Null values for both numeric fields may produce undefined weighted mean
- Payment of 0.01 USDC not completed blocks request

## How this service works

Save files — Category frequencies + Secondary-measure weighted mean: Category frequencies + Secondary-measure weighted mean 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

Two analytical reports: (1) a category frequency table showing how often each game_area value appears in the submitted rows, and (2) a weighted mean of the selected numeric field (save_kb or write_ms), weighted by the secondary measure. Both are computed locally without external lookups.
