# Transformation Throughput — Grouped Numeric Summary + Secondary-Measure Weighted Mean

> Transformation Throughput — Grouped Numeric Summary + 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 2026-10-24).

Computes a grouped numeric summary and a secondary-measure weighted mean for transformation throughput records (processed_rows, duration_seconds) across up to 200 rows.

## 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-grouped-numeric-summary-secondary-measure-f8924b88 -d '<json body>'
```

Example prompt: Can you summarize my transformation throughput records by dataset group and compute the duration_seconds weighted mean (weighted by processed_rows)? I have 4 rows across group-a and group-b with dates from 2026-10-01 to 2026-10-04, processed_rows values of 10, 20, 15, 30 and duration_seconds of 1, 2, 3, 4.

## When to prefer this

Choose this endpoint when you have up to 200 transformation throughput records with processed_rows and duration_seconds fields and need both a grouped descriptive summary and a weighted mean computed from those two measures in one call. Prefer it over general analytics APIs when you specifically need secondary-measure weighting (e.g. weighting duration by row count) alongside grouped stats, and when you want offline/local computation with no external data dependencies.

## Known failure modes

- Rows array exceeds 200 items — request rejected
- Missing required fields (row_id, dataset_group, date, processed_rows, duration_seconds) cause validation errors
- Invalid date format (not YYYY-MM-DD) triggers schema rejection
- Null values in both processed_rows and duration_seconds may produce undefined weighted mean
- row_id or dataset_group values exceeding 80 characters are rejected

## How this service works

Transformation throughput — Grouped numeric summary + Secondary-measure weighted mean: Grouped numeric summary + 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 analytical reports: (1) a grouped numeric summary (e.g. count, mean, min, max, std) of the selected measure broken down by dataset_group, and (2) a secondary-measure weighted mean where processed_rows or duration_seconds weights the other field — all computed locally without external lookups.
