# Dependency Upgrades Trailing Mean + IQR Outlier Analysis

> Dependency Upgrades Trailing Mean + IQR Outlier Analysis 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 trailing mean time series and IQR-based outlier flags for dependency upgrade metrics (packages_checked, packages_updated) across up to 200 supplied rows, returning two independent analytical reports.

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 dependency-upgrades-trailing-mean-iqr-outlier-analysis-7aaa39d9 -d '<json body>'
```

Example prompt: Analyze my dependency upgrade records for packages_checked using a trailing window of 4 and flag IQR outliers — here are the rows: [{"row_id":"r1","component":"frontend","date":"2024-01-01","packages_checked":50,"packages_updated":3},{"row_id":"r2","component":"frontend","date":"2024-01-02","packages_checked":52,"packages_updated":5},{"row_id":"r3","component":"frontend","date":"2024-01-03","packages_checked":200,"packages_updated":2}].

## When to prefer this

Choose this endpoint when you have raw dependency upgrade tabular data (packages_checked or packages_updated) and need both a rolling/trailing mean trend series and IQR-based outlier detection in a single call for up to 200 rows, without needing live data lookup, prediction, or external enrichment. Prefer it over general-purpose stats APIs when your domain is specifically software dependency upgrade metrics and you want two bundled analytical reports at low cost ($0.01 USDC).

## Known failure modes

- Fewer than 1 or more than 200 rows supplied — request rejected
- Window size larger than number of rows — insufficient data for trailing mean
- Missing required fields (row_id, date, component, packages_checked, packages_updated) — validation error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Field enum value not 'packages_checked' or 'packages_updated' — rejected
- All values null — IQR computation not possible

## How this service works

Dependency upgrades — Trailing mean series + IQR outlier flags: Trailing mean series + IQR outlier flags for supplied dependency upgrades records (packages_checked, packages_updated). 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 independent analytical reports covering: (1) a trailing mean time series computed over the specified rolling window for the chosen field (packages_checked or packages_updated), and (2) IQR-based outlier flags identifying rows whose values fall outside the interquartile range bounds. Results are derived entirely from the supplied data rows with no external lookups.
