# Tutorial Completion Duplicate Key Report and Adjacent Row Changes

> Tutorial Completion Duplicate Key Report and Adjacent Row Changes is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-29).

Analyzes tutorial completion records (starts and completions) to produce two reports: a duplicate key report and an adjacent row changes report, for up to 200 rows.

## 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-duplicate-key-report-and-adjacent-row-changes-0031a6cd -d '<json body>'
```

Example prompt: Can you run a duplicate key report and adjacent row changes analysis on my tutorial completion data? Here are the rows — each has a row_id, game_area, date, starts, and completions — and I want to check the 'completions' field for row changes.

## When to prefer this

Choose this endpoint when you have tutorial completion tracking data (up to 200 rows) and need both a duplicate key check and an adjacent row change report in a single call for a flat $0.01 USDC fee. It is best suited for data quality audits of game tutorial funnel records where you want to detect duplicates and spot anomalous transitions between consecutive entries without any external API calls or live data enrichment.

## Known failure modes

- Input array is empty or missing (minItems:1 violated)
- More than 200 rows submitted (maxItems:200 violated)
- Row missing required fields: row_id, game_area, date, starts, or completions
- Date field does not match YYYY-MM-DD pattern
- row_id or game_area exceeds 80 character maxLength
- Numeric values for starts or completions outside allowed range
- Invalid field enum value (must be 'starts' or 'completions')
- Payment not provided or insufficient (requires 0.01 USDC via x402)

## How this service works

Tutorial completion — Duplicate key report + Adjacent row changes: Duplicate key report + Adjacent row changes for supplied tutorial completion records (starts, completions). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.

## Output

Two independent analytical reports: (1) a duplicate key report identifying rows with duplicate key combinations within the supplied dataset, and (2) an adjacent row changes report showing where the selected field (starts or completions) changes between consecutive rows. Both reports are generated locally from the submitted data with no external lookups.
