# Dataset Storage Analytics — Trailing Mean Series & Missing-Value Fill

> Dataset Storage Analytics — Trailing Mean Series & Missing-Value Fill is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Computes trailing moving-average series and fills missing values in dataset storage records (used_mb, row_count) for up to 200 rows, returning two analytical reports.

- Price: $0.01/call
- Payment: x402

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 dataset-storage-analytics-trailing-mean-series-missing-value-fill-2edf207a -d '<json body>'
```

Example prompt: Run a trailing mean with a window of 3 and fill any missing used_mb values using median for these dataset storage records — I have about 50 rows grouped by dataset_group with dates from 2026-10-01 to 2026-11-20.

## When to prefer this

Choose this endpoint when you need both rolling/trailing mean smoothing and missing-value imputation on dataset storage metrics (used_mb or row_count) in a single call, for up to 200 rows, without requiring any external data source or live system integration. It is ideal for preprocessing storage time-series data before visualization or downstream analysis.

## Known failure modes

- Exceeds 200-row limit — request rejected
- Missing required fields (row_id, date, dataset_group) — validation error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Window size outside 2–200 range — rejected
- Field value outside allowed numeric range — validation error
- Empty rows array — rejected

## How this service works

Dataset storage — Trailing mean series + Explicit missing-value fill: Trailing mean series + Explicit missing-value fill for supplied dataset storage records (used_mb, row_count). 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 for the supplied dataset storage rows: (1) a trailing moving-average series computed over the specified window for the chosen field (used_mb or row_count), and (2) the same series with missing values explicitly filled using the chosen method (zero, mean, or median). All computations are performed locally without any external lookups or predictions.
