# Tutorial Completion Analytics — Numeric Row Ordering + Keyed Dataset Comparison

> Tutorial Completion Analytics — Numeric Row Ordering + Keyed Dataset Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Analyzes tutorial completion records (starts and completions) by applying numeric row ordering and keyed dataset comparison across up to 200 rows, returning two independent analytical reports.

## 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-analytics-numeric-row-ordering-keyed-dataset-a2adf853 -d '<json body>'
```

Example prompt: I have two sets of tutorial completion data for my game areas — each with up to 50 rows of starts and completions per date — can you rank the rows by 'completions' and then compare the two datasets side-by-side using the row IDs to spot differences?

## When to prefer this

Choose this endpoint when you need two simultaneous local analytical operations on tutorial completion tabular data: numeric ranking of rows by a chosen metric AND a keyed diff-style comparison between two datasets using row IDs. Ideal for game or e-learning analytics workflows where you want to audit changes between two snapshots of completion data without any external lookups. At $0.01 USDC for both reports on up to 200 rows, it is cost-effective for lightweight batch analytical tasks on pre-collected data.

## Known failure modes

- Input rows array is empty or exceeds 200 items — request rejected
- Missing required fields (row_id, game_area, date, starts, completions) in any row — validation error
- Date fields not matching YYYY-MM-DD pattern — schema validation failure
- row_id values not shared between primary and comparison dataset — comparison report may show all rows as unmatched
- Payment of 0.01 USDC not completed — 402 response requiring payment
- Null values in starts or completions fields may affect numeric ordering output

## How this service works

Tutorial completion — Numeric row ordering + Keyed dataset comparison: Numeric row ordering + Keyed dataset comparison 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 analytical reports: (1) a numeric row ordering of the supplied rows ranked by the selected field (starts or completions), and (2) a keyed dataset comparison that matches rows from both datasets by row_id and highlights differences in the chosen metric. No external data is fetched; all analysis is performed on the supplied input data.
