# Learning Resource Usage — Record Quality Audit + Category Frequencies

> Learning Resource Usage — Record Quality Audit + 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 2026-11-02).

Analyzes up to 200 learning resource usage records to produce a record quality audit and category frequency report for course groups.

## 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 learning-resource-usage-record-quality-audit-category-frequencies-aba1cb63 -d '<json body>'
```

Example prompt: Can you run a record quality audit and category frequency analysis on my learning resource usage data? I have about 150 rows with fields like course_group, date, access_count, and resource_minutes — here's the dataset.

## When to prefer this

Choose this endpoint when you need both a data quality audit and a course-group category frequency analysis on learning resource usage data in a single call for up to 200 rows. It is ideal for pre-processing or validation pipelines before reporting or downstream analytics on elearning platform data. Prefer this over general-purpose data tools when you specifically need the two-report bundle (quality + frequencies) at low cost without external dependencies.

## Known failure modes

- Fewer than 1 row submitted returns a validation error
- More than 200 rows submitted exceeds the limit and is rejected
- Rows missing required fields (row_id, course_group, date, access_count, resource_minutes) cause schema validation failure
- Dates not matching YYYY-MM-DD pattern are rejected
- Payment of 0.01 USDC not included or rejected causes 402 response

## How this service works

Learning resource usage — Record quality audit + Category frequencies: Record quality audit + Category frequencies for supplied learning resource usage records (access_count, resource_minutes). 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 record quality audit flagging data issues such as nulls, out-of-range values, or formatting problems across the supplied rows, and (2) category frequency counts showing how often each course_group appears in the dataset. Both reports are computed locally from the supplied data with no external lookups.
