# Training Assessments — Numeric Row Ordering + IQR Outlier Flags

> Training Assessments — Numeric Row Ordering + 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 2026-10-26).

Sorts training assessment records by pre_score or post_score and flags statistical outliers using IQR analysis, returning two analytical reports for 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 training-assessments-numeric-row-ordering-iqr-outlier-flags-129f6303 -d '<json body>'
```

Example prompt: I have 50 training assessment rows with row_id, course_group, date, pre_score, and post_score — can you sort them by post_score and flag any IQR outliers in the post_score column?

## When to prefer this

Choose this endpoint when you need both a ranked ordering of training assessment records and IQR-based outlier detection in a single call, with no need for live data lookups, predictions, or external integrations. It is best suited for education or training analytics workflows where you have up to 200 pre/post score rows and want lightweight, deterministic statistical summaries at minimal cost ($0.01 USDC for both reports).

## Known failure modes

- Fewer than 1 row submitted — minimum item count not met
- More than 200 rows submitted — exceeds maxItems limit
- Missing required fields (row_id, course_group, date, pre_score, post_score) on any row
- Invalid date format — must match YYYY-MM-DD pattern
- Invalid field enum value — must be 'pre_score' or 'post_score'
- All score values are null — insufficient numeric data for IQR computation
- Payment not attached or insufficient — x402 payment of 0.01 USDC required

## How this service works

Training assessments — Numeric row ordering + IQR outlier flags: Numeric row ordering + IQR outlier flags for supplied training assessments records (pre_score, post_score). 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

Two analytical reports: (1) the supplied training assessment rows reordered numerically by the chosen field (pre_score or post_score), and (2) IQR-based outlier flags indicating which rows have values that fall outside the interquartile range boundaries — all computed locally with no external lookups.
