# Pipeline Durations Grouped Summary and Histogram

> Pipeline Durations Grouped Summary and Histogram is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-24).

Computes a grouped numeric summary and equal-width histogram for pipeline duration metrics (run_seconds or processed_rows) across up to 200 supplied records.

## 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-summary-and-histogram-939c581f -d '<json body>'
```

Example prompt: Analyze my pipeline run data — here are 50 records with run_seconds and processed_rows grouped by dataset_group — give me a grouped numeric summary and an equal-width histogram with 10 bins for the run_seconds field.

## When to prefer this

Choose this endpoint when you have pipeline execution records (with run_seconds and processed_rows) and need both a grouped summary and a histogram in a single call for up to 200 rows. Ideal for data engineers or analysts who want quick descriptive statistics on ETL job performance without standing up their own analytical infrastructure. Best when you have dataset_group labels and want per-group breakdown alongside distributional analysis.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Missing required fields (row_id, dataset_group, date, run_seconds, processed_rows) cause validation errors
- Invalid date format (not YYYY-MM-DD) causes schema rejection
- bins value outside 1–30 range causes validation error
- Null values in the target field may affect histogram bin calculations
- Non-numeric values in run_seconds or processed_rows fail schema validation

## How this service works

Pipeline durations — Grouped numeric summary + Equal-width histogram: Grouped numeric summary + Equal-width histogram 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 analytical reports for the specified numeric field: (1) a grouped numeric summary with descriptive statistics (e.g. count, mean, min, max, std dev) broken down by dataset_group, and (2) an equal-width histogram showing the frequency distribution across the specified number of bins. Both reports are computed locally against the supplied rows with no external lookups.
