## 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-record-quality-audit-equal-width-histogram-b6dfa243 -d '<json body>'
```

Example prompt: Can you audit the data quality and generate a histogram with 10 bins on the 'completions' field for these tutorial completion records across my game areas? I have about 50 rows with date, starts, and completions per game area.

## When to prefer this

Choose this endpoint when you have up to 200 tutorial completion records and need both a data quality audit and a statistical histogram in a single low-cost call. It is ideal for pre-analysis data profiling of game tutorial engagement data (starts/completions by game area and date) without requiring any external data sources or live lookups. Prefer this over general analytics platforms when you want a fast, cheap, self-contained dual-report for structured tabular records.

## Known failure modes

- More than 200 rows submitted — exceeds maximum row limit
- Invalid date format (not YYYY-MM-DD) causes row rejection
- Missing required fields (row_id, game_area, date, starts, completions) triggers validation error
- Bins value outside 1–30 range rejected
- Empty rows array returns error
- Numeric values outside ±1,000,000,000,000 rejected

## How this service works

Tutorial completion — Record quality audit + Equal-width histogram: Record quality audit + Equal-width histogram 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 analytical reports: (1) a record quality audit flagging issues such as nulls, out-of-range values, or malformed rows across the supplied tutorial completion records; (2) an equal-width histogram showing frequency distribution of the selected field (starts or completions) across the specified number of bins. Results are computed locally with no external lookups.
