# Transformation Throughput Analytics — String Normalisation + Explicit Missing-Value Fill

> Transformation Throughput Analytics — String Normalisation + Explicit Missing-Value Fill 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).

Normalises string fields and fills missing values (zero, mean, or median) in transformation throughput records containing processed_rows and duration_seconds metrics, returning two analytical reports for up to 200 rows.

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-string-normalisation-explicit-e9bc8bd3 -d '<json body>'
```

Example prompt: I have 80 rows of ETL throughput records with dataset_group labels and some missing processed_rows values — can you normalise the string fields and fill those gaps using median imputation, and give me two analytical reports on the results?

## When to prefer this

Choose this endpoint when you need a combined string normalisation and missing-value imputation pass on transformation throughput records (processed_rows, duration_seconds) in a single paid call, and you want two independent analytical reports without any external API calls, live lookups, or ML predictions. It is well-suited for ETL audit pipelines, data quality preprocessing, and dashboard preparation where deterministic, local computation suffices for up to 200 rows at very low cost ($0.01 USDC).

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Missing required fields (row_id, date, processed_rows, duration_seconds) in any row — validation error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Invalid enum value for field or method — rejected with validation error
- Empty rows array — minimum 1 row required
- Numeric values outside allowed range (±1,000,000,000,000) — validation error

## How this service works

Transformation throughput — String normalisation + Explicit missing-value fill: String normalisation + Explicit missing-value fill 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 based on the supplied transformation throughput rows (up to 200): one covering string normalisation of fields like dataset_group, and one covering explicit missing-value fill for the chosen field (processed_rows or duration_seconds) using the selected method (zero, mean, or median). No external lookups or predictions are made; all processing is local and deterministic.
