# Tutorial Completion — Numeric Row Ordering + Daily Sum Series

> Tutorial Completion — Numeric Row Ordering + Daily Sum 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 data by producing a numeric row ordering report and a daily sum time series for starts or completions, using local analytical engines on up to 200 supplied 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-numeric-row-ordering-daily-sum-series-eea0853f -d '<json body>'
```

Example prompt: I have tutorial completion records with starts and completions across different game areas — can you give me a numeric row ordering and a daily sum series for the completions field? Here are 4 rows: row-1 on 2026-10-01 in group-a with 10 starts and 1 completion, row-2 on 2026-10-02 in group-b with 20 starts and 2 completions, row-3 on 2026-10-03 in group-a with 15 starts and 3 completions, and row-4 on 2026-10-04 in group-b with 30 starts and 4 completions.

## When to prefer this

Choose this endpoint when you need both a ranked numeric ordering of tutorial completion rows and a daily aggregate sum series in a single API call, at very low cost ($0.01 USDC for both reports). It is ideal for offline/batch analytical work on supplied datasets of up to 200 rows, where no live data lookup, external enrichment, or prediction is needed.

## Known failure modes

- Input array exceeds 200 rows — request will be rejected or truncated
- Missing required fields (row_id, game_area, date, starts, completions) cause validation errors
- Invalid date format (not YYYY-MM-DD) causes schema rejection
- Null values in starts or completions may affect sum calculations
- Field enum not matching 'starts' or 'completions' causes an error
- Empty rows array (minItems: 1 not met) rejected

## How this service works

Tutorial completion — Numeric row ordering + Daily sum series: Numeric row ordering + Daily sum 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 reports: (1) a numeric row ordering of the supplied tutorial completion records, and (2) a daily sum time series for the chosen metric field (starts or completions), summarizing totals per date across up to 200 rows, computed entirely from the supplied data with no external lookups.
