## 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-grouped-numeric-summary-category-4a31b737 -d '<json body>'
```

Example prompt: Can you run a grouped numeric summary and category frequency analysis on our tutorial completion data? Here are 4 rows: row-1 on 2026-10-01, game_area group-a, 10 starts, 1 completion; row-2 on 2026-10-02, game_area group-b, 20 starts, 2 completions; row-3 on 2026-10-03, game_area group-a, 15 starts, 3 completions; row-4 on 2026-10-04, game_area group-b, 30 starts, 4 completions — analyze the 'completions' field.

## When to prefer this

Choose this endpoint when you have tutorial or game onboarding completion records (up to 200 rows) and need both a grouped numeric summary and category frequency breakdown in a single call. Ideal for game analytics teams analyzing player progression through tutorials by area. Prefer this over building custom aggregations when you want a fast, low-cost ($0.01) dual-report output without setting up a data pipeline.

## Known failure modes

- Empty rows array or missing required fields (row_id, game_area, date, starts, completions) returns a validation error
- More than 200 rows submitted exceeds the limit and will be rejected
- Invalid date format (must match YYYY-MM-DD) causes schema validation failure
- Null values in starts or completions fields may be excluded from numeric aggregation
- Invalid field enum value (must be 'starts' or 'completions') causes rejection
- Payment of 0.01 USDC not provided results in 402 Payment Required response

## How this service works

Tutorial completion — Grouped numeric summary + Category frequencies: Grouped numeric summary + Category frequencies 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 grouped numeric summary of the selected field (starts or completions) segmented by game_area and/or date, and (2) category frequency counts showing how often each game_area or category appears across the supplied rows. Both reports are computed locally on the supplied data with no external lookups.
