# Tutorial Completion Duplicate Key Report + Trailing Mean Series

> Tutorial Completion Duplicate Key Report + Trailing Mean Series is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-02).

Analyzes tutorial completion records (starts and completions) to produce a duplicate key report and a trailing mean series, up to 200 rows, using local analytical engines.

## 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-trailing-mean-series-a957d9d2 -d '<json body>'
```

Example prompt: Can you check my tutorial completion data for duplicate row IDs and also compute a trailing mean of 'completions' with a window of 3, across these rows: row-1 2026-10-01 group-a starts=10 completions=1, row-2 2026-10-02 group-b starts=20 completions=2, row-3 2026-10-03 group-a starts=15 completions=3?

## When to prefer this

Choose this endpoint when you need both duplicate key detection and a rolling/trailing mean series computed together on tutorial completion data (starts and completions) in a single call, without requiring any external lookup, live data, or prediction. Ideal for game analytics pipelines doing batch data quality checks on tutorial funnel records with up to 200 rows.

## Known failure modes

- Input array is empty or missing — minimum 1 row required
- More than 200 rows submitted — request will be rejected
- Invalid date format (not YYYY-MM-DD) — row validation error
- Window parameter outside 2–200 range — parameter validation error
- Field value not 'starts' or 'completions' — enum validation error
- row_id missing or empty string — required field error

## How this service works

Tutorial completion — Duplicate key report + Trailing mean series: Duplicate key report + Trailing mean series 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

Returns two independent analytical reports: (1) a duplicate key report identifying any repeated row_id values across the submitted tutorial records, and (2) a trailing mean series for the selected field (starts or completions) computed over the specified rolling window, for up to 200 input rows.
