# Research Task Completion — Adjacent Row Changes & Keyed Dataset Comparison

> Research Task Completion — Adjacent Row Changes & Keyed Dataset Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-17).

Analyzes up to 200 rows of research task completion data, producing two reports: adjacent row changes and keyed dataset comparison between two supplied datasets.

## 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 research-task-completion-adjacent-row-changes-keyed-dataset-comparison-9efcfa9d -d '<json body>'
```

Example prompt: I have two snapshots of our research task completion records — each up to 200 rows with row_id, company_group, date, completed_tasks, and assigned_tasks — can you run both an adjacent row change analysis and a keyed comparison between the two datasets on the completed_tasks field?

## When to prefer this

Choose this endpoint when you have two local datasets of research task completion records (up to 200 rows each) and need both a row-to-row change analysis and a cross-dataset keyed comparison in a single low-cost call ($0.01 USDC). Prefer this over general analytics tools when your data is already structured with row_id, company_group, date, and task fields and you want deterministic, offline-style analysis without live lookups or external enrichment.

## Known failure modes

- Missing required fields (row_id, company_group, date, completed_tasks, assigned_tasks) causes validation failure
- Exceeding 200 rows in either dataset returns an error
- Invalid date format (not YYYY-MM-DD) causes schema rejection
- Null values in numeric fields may affect delta calculations
- Mismatched row_id keys between the two datasets may result in unmatched rows in comparison report
- Empty rows array returns an error due to minItems:1 constraint

## How this service works

Research task completion — Adjacent row changes + Keyed dataset comparison: Adjacent row changes + Keyed dataset comparison for supplied research task completion records (completed_tasks, assigned_tasks). 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 based on the supplied data: (1) an adjacent row changes report showing deltas between consecutive rows for the selected field (completed_tasks or assigned_tasks), and (2) a keyed dataset comparison report highlighting differences between the two supplied datasets matched by row_id. No external data is fetched; all analysis is performed locally on the provided rows.
