# Training Assessments — Exact Row Deduplication + Category Frequencies

> Training Assessments — Exact Row Deduplication + Category Frequencies 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).

Deduplicates training assessment records and computes category-frequency breakdowns for pre_score/post_score data across course groups, 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-exact-row-deduplication-category-frequencies-28fc08d3 -d '<json body>'
```

Example prompt: I have a list of up to 200 training assessment records with pre-scores and post-scores across different course groups — can you deduplicate exact duplicate rows and give me a frequency breakdown of how many records fall into each course group?

## When to prefer this

Choose this endpoint when you have training assessment data (pre_score, post_score per course group) and need both exact deduplication and category-frequency analysis in a single call at minimal cost. Ideal for small-to-medium datasets (up to 200 rows) where you want offline, deterministic analysis with no external data dependencies. Not suitable for datasets over 200 rows, for predictive scoring, or for live lookup enrichment.

## Known failure modes

- Rows exceeding 200 items will be rejected (maxItems constraint)
- Missing required fields (row_id, course_group, date, pre_score, post_score) will cause validation errors
- Invalid date format (non YYYY-MM-DD) will fail schema validation
- row_id values exceeding 80 characters will be rejected
- Payment of 0.01 USDC required per call via x402 protocol; unpaid calls will be rejected

## How this service works

Training assessments — Exact row deduplication + Category frequencies: Exact row deduplication + Category frequencies 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) an exact-row deduplication report identifying and removing duplicate assessment records from the submitted dataset, and (2) a category frequency table showing how many records appear per course_group value. Both reports are computed locally on the supplied data with no external lookups.
