# Research Task Completion — Base-100 Series + Date by Category Pivot

> Research Task Completion — Base-100 Series + 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).

Generates two analytical reports (Base-100 index series and a date-by-category pivot) from supplied research task completion data (completed_tasks and assigned_tasks) 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-base-100-series-date-by-category-pivot-98b21481 -d '<json body>'
```

Example prompt: Take my research task completion records for group-a and group-b from October 2026 — with completed_tasks and assigned_tasks per day — and give me both a Base-100 index series (starting from row index 0) and a date-by-category pivot for the completed_tasks field.

## When to prefer this

Choose this endpoint when you have structured research task completion records (completed_tasks, assigned_tasks) with dates and group labels, and need both a Base-100 normalized trend series and a date-by-category pivot in a single call. It is ideal for offline/batch analysis of up to 200 rows without needing external data, live predictions, or professional assessment. At $0.01 USDC for both reports together, it is cost-effective for routine productivity analytics.

## Known failure modes

- More than 200 rows submitted — request exceeds maxItems limit
- Missing required fields (row_id, date, company_group) cause validation failure
- Invalid date format (not YYYY-MM-DD) causes schema rejection
- base_index out of range (>=number of rows) causes computation error
- All values null for selected field results in empty or degenerate output
- field enum value not matching 'completed_tasks' or 'assigned_tasks' causes rejection

## How this service works

Research task completion — Base-100 series + Date by category pivot: Base-100 series + 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 reports computed locally from the supplied data: (1) a Base-100 indexed series for the selected metric field (completed_tasks or assigned_tasks), rebased to the row at base_index; and (2) a date-by-category pivot table showing values broken down by date and company_group. Up to 200 input rows are supported. No external lookups or predictions are made.
