# Pipeline Durations — Grouped Numeric Summary & Two-Measure Correlation

> Pipeline Durations — Grouped Numeric Summary & Two-Measure Correlation is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-16).

Computes a grouped numeric summary and a two-measure correlation analysis for up to 200 pipeline duration records covering run_seconds and 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-grouped-numeric-summary-two-measure-correlation-6ccad037 -d '<json body>'
```

Example prompt: I have pipeline run data for the past month — can you give me a grouped numeric summary by dataset_group and also compute the correlation between run_seconds and processed_rows? Here are up to 200 records with row_id, date, dataset_group, run_seconds, and processed_rows fields.

## When to prefer this

Choose this endpoint when you have up to 200 pipeline execution records and need both a grouped descriptive summary and a bivariate correlation between run_seconds and processed_rows in a single low-cost call. Ideal for lightweight ETL monitoring or ad-hoc performance analysis without requiring a full analytics platform.

## Known failure modes

- More than 200 rows submitted — request will be rejected due to row limit
- Missing required fields (row_id, dataset_group, date, run_seconds, processed_rows) cause validation errors
- Non-numeric or null values in run_seconds or processed_rows may affect correlation output
- Invalid date format (not YYYY-MM-DD) triggers schema validation failure
- Empty rows array returns an error

## How this service works

Pipeline durations — Grouped numeric summary + Two-measure correlation: Grouped numeric summary + Two-measure correlation 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

Two independent analytical reports: (1) a grouped numeric summary showing statistics (mean, min, max, count, etc.) for the chosen field broken down by dataset_group, and (2) a correlation analysis between run_seconds and processed_rows across all supplied rows. Both reports are computed locally from the submitted data with no external lookups.
