# Research Task Completion — Adjacent Row Changes + Date by Category Pivot

> Research Task Completion — Adjacent Row Changes + Date by Category Pivot 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 research task completion records to produce two reports: adjacent row-to-row change analysis and a date-by-category pivot table, for up to 200 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 research-task-completion-adjacent-row-changes-date-by-category-pivot-4a41ca1c -d '<json body>'
```

Example prompt: I have up to 200 rows of research task completion records with fields row_id, company_group, date, completed_tasks, and assigned_tasks — can you run two reports on them: one showing adjacent row-to-row changes and one showing a date-by-category pivot, focused on the completed_tasks field?

## When to prefer this

Choose this endpoint when you need two specific analytical views on research task completion data simultaneously — sequential row-over-row change detection and a date-by-category pivot — without needing external data sources, predictions, or live lookups. It is ideal for lightweight, batch analytical workflows on small-to-medium tabular datasets (≤200 rows) with company group and date dimensions, especially when cost efficiency ($0.01 for two reports) matters.

## Known failure modes

- Input array exceeds 200 rows — request will be rejected
- Missing required fields (row_id, company_group, date, completed_tasks, assigned_tasks) cause validation errors
- Date fields not matching YYYY-MM-DD pattern result in schema errors
- Invalid field enum value (not 'completed_tasks' or 'assigned_tasks') causes rejection
- Empty rows array (minItems:1 violated) returns error
- Numeric values outside ±1,000,000,000,000 bounds may be rejected

## How this service works

Research task completion — Adjacent row changes + Date by category pivot: Adjacent row changes + Date by category pivot 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: (1) an adjacent row changes report showing the delta in the selected metric (completed_tasks or assigned_tasks) between consecutive rows, and (2) a date-by-category pivot table summarizing the selected metric broken down by date and company_group. Both reports are derived entirely from the supplied input data with no external lookups.
