# Tutorial Completion Analytics: Equal-Width Histogram + Keyed Dataset Comparison

> Tutorial Completion Analytics: Equal-Width Histogram + 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 2026-10-28).

Generates an equal-width histogram and a keyed dataset comparison report for tutorial completion data (starts and completions) across 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-analytics-equal-width-histogram-keyed-dataset-bfadaa34 -d '<json body>'
```

Example prompt: Can you analyze the distribution of tutorial starts in 5 bins and compare these two datasets of tutorial completion records — the first has rows for group-a and group-b from October 2026, and the second is a slightly different version of the same records — to spot any differences?

## When to prefer this

Choose this endpoint when you have tutorial completion tabular data (starts and completions per game area and date) and need both a numeric distribution histogram and a side-by-side row-level comparison between two versions of the dataset in a single low-cost call. Ideal for game learning analytics teams doing weekly or A/B cohort audits without needing external data sources or prediction models.

## Known failure modes

- Input rows array is empty or exceeds 200 items — validation error
- Missing required row fields (row_id, game_area, date, starts, completions) — schema rejection
- bins value outside 1–30 range — validation error
- date field does not match YYYY-MM-DD pattern — schema rejection
- Mismatched or missing row_ids between primary and comparison dataset — comparison may produce incomplete results
- Null numeric values in starts or completions — may be excluded from histogram computation

## How this service works

Tutorial completion — Equal-width histogram + Keyed dataset comparison: Equal-width histogram + 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) an equal-width histogram showing bin ranges and counts for the selected numeric field (starts or completions) across up to 200 input rows, and (2) a keyed dataset comparison report matching rows by row_id between the primary and secondary datasets to highlight differences in starts and completions values.
