# Training Assessments Trailing Mean Series + Secondary-Measure Weighted Mean

> Training Assessments Trailing Mean Series + 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 2026-10-26).

Computes a rolling/trailing mean time series and a secondary-measure weighted mean for training assessment records containing pre_score and post_score fields.

## 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-trailing-mean-series-secondary-measure-weighted-e537a706 -d '<json body>'
```

Example prompt: Can you run a trailing mean series with a window of 3 on the pre_score field for these 12 training assessment records, each with a row_id, course_group, date, pre_score, and post_score, and also give me the secondary-measure weighted mean?

## When to prefer this

Choose this endpoint when you need both a time-based rolling/trailing mean series AND a secondary-measure weighted mean in a single API call for training assessment data with pre_score and post_score fields, and your dataset is up to 200 rows. It is ideal for offline or batch analytics where no live data lookup, prediction, or external enrichment is needed, and cost efficiency matters ($0.01 USDC for two reports).

## Known failure modes

- Fewer than 1 row supplied — minimum row count not met
- More than 200 rows supplied — exceeds maximum batch size
- Invalid date format (must be YYYY-MM-DD)
- Window size outside allowed range of 2–200
- Missing required fields (row_id, course_group, date, pre_score, or post_score)
- Invalid field value — must be 'pre_score' or 'post_score'
- Null scores in all rows may result in empty or degenerate statistics
- Payment failure or insufficient USDC balance via x402 protocol

## How this service works

Training assessments — Trailing mean series + Secondary-measure weighted mean: Trailing mean series + Secondary-measure weighted mean 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 independent analytical reports for the supplied training assessment data: (1) a trailing/rolling mean time series computed over the specified window for the chosen score field (pre_score or post_score), and (2) a secondary-measure weighted mean. Both reports are derived entirely from the supplied rows (up to 200) with no external lookups or predictions.
