# Transformation Throughput — Equal-Width Histogram + IQR Outlier Flags

> Transformation Throughput — Equal-Width Histogram + IQR Outlier Flags 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).

Generates an equal-width histogram and IQR-based outlier flags for transformation throughput data (processed_rows or duration_seconds) from up to 200 supplied records.

## 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-iqr-outlier-flags-ccc0095b -d '<json body>'
```

Example prompt: Analyze the distribution of processed_rows for these 8 ETL runs using 10 equal-width histogram bins and flag any IQR outliers: row-1 on 2024-01-01 group-a 5000 rows 12s, row-2 on 2024-01-02 group-a 4800 rows 11s, row-3 on 2024-01-03 group-b 9500 rows 22s, row-4 on 2024-01-04 group-b 4900 rows 12s, row-5 on 2024-01-05 group-a 5100 rows 13s, row-6 on 2024-01-06 group-a 200 rows 9s, row-7 on 2024-01-07 group-b 4950 rows 11s, row-8 on 2024-01-08 group-b 5050 rows 12s.

## When to prefer this

Choose this endpoint when you have raw transformation throughput records (processed_rows, duration_seconds) and need both a histogram distribution view and IQR outlier detection in a single call without standing up local analytics infrastructure. Ideal for lightweight, on-demand statistical profiling of ETL pipeline logs up to 200 rows. Not suitable for real-time streaming analysis, time-series forecasting, or datasets exceeding 200 rows.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- bins value outside 1–30 range causes rejection
- field value not one of 'processed_rows' or 'duration_seconds' causes enum validation error
- All null values in the chosen field may produce empty or degenerate histogram
- Insufficient data variance may yield trivial IQR results with all or no rows flagged

## How this service works

Transformation throughput — Equal-width histogram + IQR outlier flags: Equal-width histogram + IQR outlier flags 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 for the specified field: (1) an equal-width histogram breaking the data into the requested number of bins with counts per bin, and (2) IQR-based outlier flags identifying which rows fall below Q1−1.5×IQR or above Q3+1.5×IQR, along with their row_ids and values. All computation is performed locally on the supplied data with no external lookups.
