# Tutorial Completion — Exact Row Deduplication + Numeric Distribution

> Tutorial Completion — Exact Row Deduplication + Numeric Distribution 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).

Deduplicates tutorial completion records by exact row match and computes a numeric distribution report for a chosen metric (starts or completions), returning two analytical reports for up to 200 rows.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-exact-row-deduplication-numeric-distribution-b89d6b66 -d '<json body>'
```

Example prompt: I have up to 200 rows of tutorial completion data with fields like row_id, game_area, date, starts, and completions — can you deduplicate them by exact row match and also give me a numeric distribution report on the 'completions' field?

## When to prefer this

Choose this endpoint when you need both exact duplicate detection and a numeric distribution summary on tutorial completion data in a single low-cost call ($0.01 USDC). It is ideal for offline/local analytical processing of up to 200 rows without requiring any external data sources, live lookups, or predictions. Prefer alternatives if you need more than 200 rows, other analytical operations (e.g. histograms, correlations, pivot tables), or data from domains other than tutorial/game completion tracking.

## Known failure modes

- Input array is empty or missing — returns validation error
- More than 200 rows submitted — exceeds maxItems limit
- Invalid date format not matching YYYY-MM-DD pattern — schema validation error
- Missing required fields (row_id, game_area, date, starts, completions) on any row — rejection
- Invalid 'field' enum value (must be 'starts' or 'completions') — schema error
- Payment not processed — x402 payment required error

## How this service works

Tutorial completion — Exact row deduplication + Numeric distribution: Exact row deduplication + Numeric distribution 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 reports: (1) an exact row deduplication report identifying and removing duplicate records from the supplied tutorial completion rows, and (2) a numeric distribution report (e.g. min, max, mean, percentiles, frequency bins) for the chosen field ('starts' or 'completions'). Both reports are computed locally on the supplied data with no external lookups.
