# Pipeline Durations — Base-100 Series + Two-Measure Correlation

> Pipeline Durations — Base-100 Series + 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 2026-10-23).

Computes a Base-100 index series and a two-measure correlation report for supplied pipeline duration records (run_seconds and processed_rows) — up to 200 rows, no external data required.

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-base-100-series-two-measure-correlation-0d46a4cb -d '<json body>'
```

Example prompt: Can you index my pipeline run times as a Base-100 series starting from the first row, and also show me the correlation between run_seconds and processed_rows? Here are my records: row-1 on 2025-01-01 ran 120 seconds and processed 5000 rows (group-a), row-2 on 2025-01-02 ran 150 seconds and processed 6200 rows (group-b), row-3 on 2025-01-03 ran 90 seconds and processed 4100 rows (group-a).

## When to prefer this

Choose this endpoint when you have pipeline execution records with numeric duration and volume fields and need both a relative trend index (Base-100 series) and a linear correlation between two measures computed locally — without external API calls, ML models, or live data. Ideal for data engineers wanting lightweight, reproducible analytical summaries on small-to-medium datasets (up to 200 rows) at minimal cost ($0.01 USDC covers both reports).

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Required fields (row_id, date, run_seconds, processed_rows, dataset_group) missing from one or more rows — validation error
- base_index out of range (0–199) or references a non-existent row — error returned
- Null values in run_seconds or processed_rows may reduce correlation quality or cause partial results
- Malformed date strings not matching YYYY-MM-DD pattern — validation failure
- Fewer than 2 rows provided — correlation cannot be computed meaningfully

## How this service works

Pipeline durations — Base-100 series + Two-measure correlation: Base-100 series + 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 Base-100 index series showing each row's selected measure (run_seconds or processed_rows) relative to the baseline row, and (2) a two-measure correlation report quantifying the relationship between run_seconds and processed_rows across the supplied rows. No external lookups or predictions are made; all computation uses the supplied data only.
