## 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-record-quality-audit-string-c1aa6b3c -d '<json body>'
```

Example prompt: Can you run a full data quality audit, string normalisation, and adjacent row change report on these tutoring session records — I have up to 50 rows with fields like row_id, course_group, date, session_minutes, and session_count, and I want the report focused on session_minutes?

## When to prefer this

Choose this endpoint when you have up to 200 tutoring session records and need a combined data quality audit, string normalisation, and adjacent row change detection in a single low-cost call. It is ideal for pre-processing education session data before analysis or reporting, especially when you do not need live lookups, predictions, or external integrations — just local analytical reports on supplied data.

## Known failure modes

- Exceeding 200 rows results in rejection or truncation
- Missing required fields (row_id, date, course_group) causes validation errors
- Invalid date format (non-YYYY-MM-DD) triggers schema rejection
- Numeric values outside allowed range cause input rejection
- Submitting an empty rows array returns an error
- Invalid field enum value (not session_minutes or session_count) causes schema validation failure

## How this service works

Tutoring sessions — Record quality audit + String normalisation + Adjacent row changes: Record quality audit + String normalisation + Adjacent row changes 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 for the submitted tutoring session rows: (1) a record quality audit identifying missing, malformed, or out-of-range values; (2) a string normalisation report showing standardised versions of text fields such as course_group; and (3) an adjacent row changes report highlighting where the chosen numeric field (session_minutes or session_count) changes between consecutive rows. All computed locally without external lookups.
