# Training Assessments — Record Quality Audit + String Normalisation + Secondary-Measure Weighted Mean

> Training Assessments — Record Quality Audit + String Normalisation + 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 2026-10-29).

Runs three local analytical reports on training assessment data (pre_score, post_score): a record quality audit, string normalisation, and a secondary-measure weighted mean — up to 200 rows per call.

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 training-assessments-record-quality-audit-string-normalisation-ed91e04c -d '<json body>'
```

Example prompt: Can you run a record quality audit, string normalisation, and weighted mean report on my training assessment data? I have 4 rows with pre_score and post_score values across course groups A and B — use post_score as the secondary measure field.

## When to prefer this

Choose this endpoint when you need a bundled, cost-efficient single-call solution for three complementary data-quality and statistical operations on training assessment records (pre_score/post_score) with up to 200 rows. It is best suited for offline/batch analytical use rather than real-time prediction, external enrichment, or professional assessment — all processing is local.

## Known failure modes

- Rows array exceeds 200 items — request rejected
- Missing required fields (row_id, course_group, date, pre_score, post_score) on any row — validation error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Invalid field enum value (not pre_score or post_score) — rejected
- Empty rows array — rejected
- Payment not provided or insufficient — 402 response

## How this service works

Training assessments — Record quality audit + String normalisation + Secondary-measure weighted mean: Record quality audit + String normalisation + Secondary-measure weighted mean for supplied training assessments records (pre_score, post_score). Up to 200 rows; 3 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 3 supplied-data reports for up to 200 rows.

## Output

Three independent analytical reports: (1) a record quality audit flagging data issues in the supplied rows, (2) a string normalisation report cleaning the course_group and date string fields, and (3) a secondary-measure weighted mean computed over the selected field (pre_score or post_score) — all processed locally with no external lookups.
