# Tutoring Sessions — Record Quality Audit + String Normalisation + Keyed Dataset Comparison

> Tutoring Sessions — Record Quality Audit + String Normalisation + Keyed Dataset Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-25).

Runs three local analytical reports on tutoring session records: a record quality audit, string normalisation, and keyed comparison between two datasets — for 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 tutoring-sessions-record-quality-audit-string-normalisation-keyed-d20cb705 -d '<json body>'
```

Example prompt: Can you run a quality audit, string normalisation, and keyed comparison on my two sets of tutoring session records? Here's the primary dataset with rows for course groups like 'group-a' and 'group-b' with session_minutes and session_count, and here's the second dataset to compare against — up to 200 rows each.

## When to prefer this

Choose this endpoint when you need to validate, clean, and compare structured tutoring session tabular data without any live lookups or external data sources. It is ideal for offline data pipeline quality gates, pre-import validation, or reconciling two exports of the same tutoring dataset. It is not suitable for predictions, live data fetching, or datasets larger than 200 rows.

## Known failure modes

- More than 200 rows submitted — request rejected or truncated
- Missing required fields (row_id, date, course_group, session_minutes, session_count) — validation error
- Malformed date format (not YYYY-MM-DD) — schema rejection
- Numeric values outside allowed range (±1,000,000,000,000) — validation error
- Empty rows array — minimum items constraint violation
- Mismatched row_ids between primary and comparison dataset — keyed comparison may yield all-unmatched results

## How this service works

Tutoring sessions — Record quality audit + String normalisation + Keyed dataset comparison: Record quality audit + String normalisation + Keyed dataset comparison 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 nulls, out-of-range values, and format issues in session_minutes and session_count fields; (2) a string normalisation report for course_group and other text fields; and (3) a keyed dataset comparison report showing row-level differences between the primary and secondary datasets matched by row_id.
