# Transformation Throughput Analytics: Category Frequencies + Secondary-Measure Weighted Mean

> Transformation Throughput Analytics: Category Frequencies + 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 2026-10-15).

Computes category-level frequencies and a secondary-measure weighted mean for transformation throughput records (processed_rows, duration_seconds) across up to 200 rows in two independent analytical reports.

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 transformation-throughput-analytics-category-frequencies-secondary-485fa7ac -d '<json body>'
```

Example prompt: Analyze my transformation throughput logs — here are up to 200 rows with row_id, dataset_group, date, processed_rows, and duration_seconds fields — and give me two reports: category frequencies by dataset_group and the weighted mean of processed_rows using duration_seconds as the weight.

## When to prefer this

Choose this endpoint when you have transformation throughput records (ETL or pipeline logs) with categorical groupings and two numeric measures, and you need both a frequency distribution of categories AND a weighted mean in a single cost-efficient call. Ideal when you have up to 200 rows and want self-contained local computation with no external data lookups or live integrations.

## Known failure modes

- More than 200 rows submitted — request rejected or truncated
- Missing required fields (row_id, dataset_group, date, processed_rows, duration_seconds) on any row — validation error
- Invalid date format (must be YYYY-MM-DD) — schema validation failure
- Numeric values outside allowed range (±1,000,000,000,000) — rejection
- All values for the selected measure are null — weighted mean cannot be computed
- Payment of 0.01 USDC not completed — 402 Payment Required response

## How this service works

Transformation throughput — Category frequencies + Secondary-measure weighted mean: Category frequencies + Secondary-measure weighted mean for supplied transformation throughput records (processed_rows, 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 independent analytical reports: (1) category frequencies showing how often each dataset_group value appears in the submitted rows, and (2) a weighted mean of the selected measure field (processed_rows or duration_seconds) with the other measure used as the weight — summarized across up to 200 input records.
