# Pipeline Durations — Adjacent Row Changes & IQR Outlier Flags

> Pipeline Durations — Adjacent Row Changes & IQR Outlier Flags is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Analyzes supplied pipeline duration records to compute adjacent row-to-row changes and flag IQR-based outliers for run_seconds or processed_rows.

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 pipeline-durations-adjacent-row-changes-iqr-outlier-flags-90e6d091 -d '<json body>'
```

Example prompt: Can you analyze these pipeline run records for adjacent row-to-row changes and flag any IQR outliers in the run_seconds field? I have up to 50 rows with date, row_id, dataset_group, run_seconds, and processed_rows.

## When to prefer this

Choose this endpoint when you have up to 200 rows of pipeline duration data and need both sequential delta analysis and IQR-based statistical outlier detection in a single $0.01 call, without requiring any external data sources or live lookups. Ideal for data engineering teams doing post-run pipeline health checks or regression analysis on batch job durations.

## Known failure modes

- Missing required fields (row_id, date, dataset_group) cause validation errors
- Exceeding 200 rows returns an error or truncation
- Invalid date format (not YYYY-MM-DD) fails schema validation
- Null values in run_seconds or processed_rows may affect outlier calculations
- Selecting a field enum value not in ['run_seconds','processed_rows'] returns an error
- Fewer than 4 rows may produce unreliable IQR statistics

## How this service works

Pipeline durations — Adjacent row changes + IQR outlier flags: Adjacent row changes + IQR outlier flags for supplied pipeline durations records (run_seconds, processed_rows). 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 independent analytical reports: (1) adjacent row-to-row change values for the selected field across up to 200 supplied rows, and (2) IQR-based outlier flags identifying records that fall outside the interquartile range, all computed locally with no external lookups.
