# Tutorial Completion — Numeric Interval Filter + Adjacent Row Changes

> Tutorial Completion — Numeric Interval Filter + Adjacent Row Changes is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-26).

Filters tutorial completion rows by a numeric interval and computes adjacent row changes for starts or completions data, 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-numeric-interval-filter-adjacent-row-changes-0569de44 -d '<json body>'
```

Example prompt: I have tutorial completion data for my game areas — can you filter rows where 'starts' is between 10 and 50, and also show me the adjacent row changes across all rows? Here's my data: 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.

## When to prefer this

Choose this endpoint when you have tabular tutorial completion data (up to 200 rows) and need both a numeric range filter and adjacent row delta analysis in a single low-cost call. It is ideal for game analytics workflows where you want to isolate rows within a value band and simultaneously understand row-to-row momentum, without needing live data lookup, prediction, or external enrichment.

## Known failure modes

- Fewer than 1 row provided — API rejects with validation error
- More than 200 rows submitted — exceeds maxItems limit
- Invalid date format (not YYYY-MM-DD) — schema pattern validation failure
- Field value not in enum ['starts','completions'] — rejected
- Minimum greater than maximum — may produce empty interval filter result
- Null numeric values in starts/completions — may affect adjacent change calculations

## How this service works

Tutorial completion — Numeric interval filter + Adjacent row changes: Numeric interval filter + Adjacent row changes 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) rows filtered to those where the chosen field ('starts' or 'completions') falls within the specified minimum–maximum interval, and (2) adjacent row changes showing the difference between consecutive row values for that field — all computed locally without external lookup.
