# Pipeline Durations — Grouped Numeric Summary + Adjacent Row Changes

> Pipeline Durations — Grouped Numeric Summary + Adjacent Row Changes is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Computes grouped numeric summaries and adjacent row-to-row change analysis for pipeline duration records (run_seconds, processed_rows) across up to 200 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-grouped-numeric-summary-adjacent-row-changes-e2fe4173 -d '<json body>'
```

Example prompt: Analyze these pipeline run records and give me both a grouped numeric summary and the adjacent row changes for run_seconds — here are 4 rows: row-1 on 2026-10-01 group-a 10s 1 row, row-2 on 2026-10-02 group-b 20s 2 rows, row-3 on 2026-10-03 group-a 15s 3 rows, row-4 on 2026-10-04 group-b 30s 4 rows.

## When to prefer this

Choose this endpoint when you have tabular pipeline execution records with group labels and want both group-level descriptive statistics and sequential delta analysis in a single low-cost call ($0.01 USDC for up to 200 rows). It is ideal for data engineering monitoring workflows where you need to understand performance distribution across groups and catch run-to-run changes without setting up your own analytics stack.

## Known failure modes

- Missing required fields (row_id, dataset_group, date, run_seconds, processed_rows) cause validation errors
- Supplying more than 200 rows exceeds the row limit and may be rejected
- Invalid date format (not YYYY-MM-DD) triggers pattern validation failure
- Null values in the selected numeric field may affect summary statistics or be excluded
- Empty rows array (minItems:1 violated) returns an error
- Field enum value other than 'run_seconds' or 'processed_rows' is rejected

## How this service works

Pipeline durations — Grouped numeric summary + Adjacent row changes: Grouped numeric summary + Adjacent row changes 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) a grouped numeric summary (e.g. count, min, max, mean, std) broken down by dataset_group for the selected field (run_seconds or processed_rows), and (2) an adjacent row changes report showing the delta between consecutive records for the selected field — all computed locally against the supplied data rows.
