# Tutoring Sessions Data Quality & Analytics — Record Audit, String Normalisation, Two-Measure Correlation

> Tutoring Sessions Data Quality & Analytics — Record Audit, String Normalisation, Two-Measure Correlation 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 a two-measure correlation between session_minutes and 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-analytics-record-audit-string-75d63e6f -d '<json body>'
```

Example prompt: Can you run a record quality audit, string normalisation, and two-measure correlation on these tutoring session records I have — it's about 50 rows with fields for session_minutes and session_count, course_group, and date?

## When to prefer this

Choose this endpoint when you need quick, self-contained analytical reports on tutoring session data (up to 200 rows) without external dependencies. It bundles three reports — quality audit, string normalisation, and correlation — in a single low-cost call ($0.01 USDC), making it ideal for education data pipelines needing lightweight data cleaning and validation before downstream processing or reporting.

## Known failure modes

- More than 200 rows submitted — exceeds the max row limit
- Missing required fields (row_id, course_group, date, session_minutes, session_count) causing schema validation failure
- Invalid date format (must be YYYY-MM-DD) causing rejection
- Payment not included or insufficient USDC balance (0.01 USDC required)
- Empty rows array (minimum 1 row required)
- Numeric values outside allowed range (-1T to 1T)

## How this service works

Tutoring sessions — Record quality audit + String normalisation + Two-measure correlation: Record quality audit + String normalisation + Two-measure correlation 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

Three analytical reports covering: (1) a record quality audit flagging missing, null, or out-of-range values across the submitted rows; (2) normalised string output for course_group and other string fields; and (3) a two-measure correlation result between session_minutes and session_count. All analysis is performed locally on the submitted data with no external lookups.
