## 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-grouped-numeric-summary-numeric-row-ordering-389eb00a -d '<json body>'
```

Example prompt: Can you run a grouped numeric summary and numeric row ordering on our training assessment data — I have up to 50 rows with pre_score and post_score fields across two course groups, and I want both reports using pre_score as the analysis field?

## When to prefer this

Choose this endpoint when you have tabular training assessment data with pre/post numeric scores and need both group-level statistical summaries and numerically ordered row rankings in a single call. It is ideal for education analytics, L&D dashboards, and cohort evaluation workflows where you supply the data directly (no external data sources needed) and want lightweight, fast computation without setting up a local analytics pipeline. Best for datasets up to 200 rows; not suitable for real-time scoring, predictive modeling, or live database lookups.

## Known failure modes

- Fewer than 1 or more than 200 rows submitted — request rejected
- Missing required fields (row_id, course_group, date, pre_score, post_score) on any row — validation error
- Invalid date format (must match YYYY-MM-DD) — schema validation failure
- Null values in the selected score field may affect ranking completeness
- Invalid field enum value (must be pre_score or post_score) — rejected
- Payment not included or insufficient — x402 payment required error

## How this service works

Training assessments — Grouped numeric summary + Numeric row ordering: Grouped numeric summary + Numeric row ordering 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

Returns two analytical reports: (1) a grouped numeric summary aggregating the chosen score field (pre_score or post_score) by course_group, including statistics such as mean, min, max, and count per group; and (2) a numeric row ordering that ranks all supplied assessment rows by the selected numeric field. Both reports are computed locally on the supplied data with no external lookups.
