# Pipeline Durations Analytics: Numeric Distribution + Two-Measure Correlation

> Pipeline Durations Analytics: Numeric Distribution + 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 numeric distribution report for pipeline run_seconds and a two-measure correlation report between run_seconds and processed_rows for supplied pipeline duration records (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-analytics-numeric-distribution-two-measure-2cf1e667 -d '<json body>'
```

Example prompt: Can you run a numeric distribution and two-measure correlation analysis on these pipeline duration records — I have up to 50 rows each with run_seconds and processed_rows — and tell me how the run time is distributed and whether it correlates with row count?

## When to prefer this

Choose this endpoint when you have up to 200 pipeline duration records with run_seconds and processed_rows fields and need both a statistical distribution summary and a two-measure correlation report in a single paid call. Ideal for data engineers and analysts who want local, offline-style statistical analysis without sending data to a third-party ML service or standing up their own analytics infrastructure.

## Known failure modes

- Fewer than 1 row submitted — request rejected
- More than 200 rows submitted — request rejected with maxItems violation
- Missing required fields (row_id, date, run_seconds, processed_rows, dataset_group) in any row — validation error
- Invalid date format (not YYYY-MM-DD) — pattern validation failure
- Null values in numeric fields may reduce correlation reliability
- Payment of 0.01 USDC not completed — 402 Payment Required response

## How this service works

Pipeline durations — Numeric distribution + Two-measure correlation: Numeric distribution + 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

Returns two analytical reports: (1) a numeric distribution report for the chosen field (run_seconds or processed_rows), including descriptive statistics such as min, max, mean, percentiles, and spread; and (2) a two-measure correlation report quantifying the linear relationship between run_seconds and processed_rows across the supplied rows. No external data is fetched; all analysis is performed locally on the supplied records.
