# Tutoring Sessions Data Quality Audit, Deduplication & Histogram

> Tutoring Sessions Data Quality Audit, Deduplication & Histogram 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).

Runs three analytical reports on tutoring session records: a record quality audit, exact row deduplication, and an equal-width histogram for session_minutes or session_count.

## 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 tutoring-sessions-data-quality-audit-deduplication-histogram-89588538 -d '<json body>'
```

Example prompt: Can you audit the quality of my tutoring session records, remove any exact duplicates, and generate a 10-bin histogram on session_minutes? Here are up to 200 rows with fields row_id, course_group, date, session_minutes, and session_count.

## When to prefer this

Choose this endpoint when you need to simultaneously assess data quality, remove duplicate records, and understand numeric distributions in tutoring session datasets — all in a single low-cost call. Ideal for education analytics pipelines preparing data for downstream reporting, when you have up to 200 rows and want three analytical perspectives without making separate API calls or using external compute.

## Known failure modes

- More than 200 rows submitted — request rejected due to row limit
- Missing required fields (row_id, date, course_group) causing validation failure
- Invalid date format (not YYYY-MM-DD) causing parse error
- bins parameter out of range (must be 1–30)
- All rows are duplicates, resulting in empty deduplication output
- Numeric values outside allowed range causing rejection
- Empty rows array submitted

## How this service works

Tutoring sessions — Record quality audit + Exact row deduplication + Equal-width histogram: Record quality audit + Exact row deduplication + Equal-width histogram for supplied tutoring sessions records (session_minutes, session_count). 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

Returns three independent reports: (1) a record quality audit flagging missing, null, or malformed values per row; (2) an exact row deduplication report identifying and removing fully duplicate records; and (3) an equal-width histogram with configurable bin count showing the frequency distribution of the selected numeric field (session_minutes or session_count) across up to 200 rows.
