# Transformation Throughput — Equal-Width Histogram + Secondary-Measure Weighted Mean

> Transformation Throughput — Equal-Width Histogram + 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 2026-10-28).

Computes an equal-width histogram and a secondary-measure weighted mean for transformation throughput records (processed_rows, duration_seconds) from up to 200 supplied 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-equal-width-histogram-secondary-measure-ba55008d -d '<json body>'
```

Example prompt: Can you analyze my transformation throughput data — I have 150 pipeline run records with processed_rows and duration_seconds fields — and give me both an equal-width histogram of processed_rows split into 10 bins plus a weighted mean of duration_seconds weighted by processed_rows?

## When to prefer this

Choose this endpoint when you need to quickly analyze the statistical distribution and weighted central tendency of transformation throughput data (processed rows and duration) without needing external data, predictions, or professional assessment — especially when you want both a histogram and a weighted mean computed together in a single call for up to 200 records at minimal cost.

## Known failure modes

- More than 200 rows submitted — request rejected or truncated
- Missing required fields (row_id, date, processed_rows, duration_seconds) cause validation errors
- Bins parameter outside range 1–30 returns error
- Null values in processed_rows or duration_seconds may affect weighted mean calculation
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- Payment of 0.01 USDC not included or rejected causes 402 response

## How this service works

Transformation throughput — Equal-width histogram + Secondary-measure weighted mean: Equal-width histogram + 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) an equal-width histogram of the chosen primary field (processed_rows or duration_seconds) divided into the specified number of bins, showing frequency distribution across bins; and (2) a weighted mean of the secondary measure where weights are derived from the primary measure — all computed locally from the supplied row data with no external lookups.
