# Tutorial Completion Data Quality Audit — Record Quality, String Normalisation & IQR Outlier Flags

> Tutorial Completion Data Quality Audit — Record Quality, String Normalisation & IQR Outlier Flags 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 tutorial completion records (starts and completions): record quality audit, string normalisation, and IQR-based outlier detection — all locally, with no external calls.

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 tutorial-completion-data-quality-audit-record-quality-string-136e3753 -d '<json body>'
```

Example prompt: Can you run a data quality audit, string normalisation, and IQR outlier check on these tutorial completion records — I have up to 150 rows with row_id, game_area, date, starts, and completions columns, and I want to flag on the 'completions' field?

## When to prefer this

Choose this endpoint when you need a bundled, cost-effective three-in-one data quality pass on tutorial completion records (up to 200 rows) covering quality auditing, string normalisation, and IQR outlier detection in a single API call. It is ideal for game analytics pipelines that need quick pre-processing validation of starts/completions data before downstream analysis, without requiring any external lookups or live data.

## Known failure modes

- Input array exceeds 200 rows — request will be rejected
- Missing required fields (row_id, game_area, date, starts, completions) causes validation error
- Invalid date format (not YYYY-MM-DD) triggers schema rejection
- No rows submitted (minItems:1 not met) causes error
- Invalid 'field' enum value (not 'starts' or 'completions') causes rejection

## How this service works

Tutorial completion — Record quality audit + String normalisation + IQR outlier flags: Record quality audit + String normalisation + IQR outlier flags for supplied tutorial completion records (starts, completions). 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 independent analytical reports: (1) a record quality audit identifying malformed, null, or inconsistent records; (2) a string normalisation report cleaning and standardising text fields like game_area; and (3) an IQR outlier flags report identifying statistically anomalous values in the selected numeric field (starts or completions). All analysis is performed locally on the submitted rows.
