# Network Links Two-Measure Correlation + Secondary-Measure Weighted Mean

> Network Links Two-Measure Correlation + Secondary-Measure Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-29).

Computes Pearson correlation between transferred_mb and duration_seconds, plus a weighted mean of a secondary measure, for up to 200 network link records in a single API call.

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 network-links-two-measure-correlation-secondary-measure-weighted-mean-536c9dbd -d '<json body>'
```

Example prompt: Can you run a two-measure correlation between transferred_mb and duration_seconds plus a weighted mean of transferred_mb on my network link records? Here are up to 200 rows with row_id, component, date, transferred_mb, and duration_seconds.

## When to prefer this

Choose this endpoint when you need both a correlation coefficient between two numeric network measures AND a weighted mean in a single low-cost call ($0.01 USDC) on up to 200 rows of network link records. Ideal for quick statistical validation of network traffic data without requiring a full analytics platform. Prefer this over general-purpose analytics APIs when working specifically with transferred_mb and duration_seconds fields and needing both reports bundled together.

## Known failure modes

- Missing required row fields (row_id, date, transferred_mb, duration_seconds) causes validation error
- Submitting more than 200 rows exceeds the maxItems limit and is rejected
- Invalid date format (not YYYY-MM-DD) triggers pattern validation failure
- Null values in both measure columns may cause correlation computation to fail or return NaN
- field enum value outside ['transferred_mb','duration_seconds'] causes schema rejection

## How this service works

Network links — Two-measure correlation + Secondary-measure weighted mean: Two-measure correlation + Secondary-measure weighted mean for supplied network links records (transferred_mb, duration_seconds). 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) the Pearson correlation coefficient between transferred_mb and duration_seconds across all submitted rows, and (2) a weighted mean of the selected secondary measure (transferred_mb or duration_seconds). Both computations are performed locally using the supplied data, with no external lookups or predictions.
