# Research Task Completion — Category Frequencies + Base-100 Series

> Research Task Completion — Category Frequencies + Base-100 Series 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 on research task completion data: category-level frequency counts and a base-100 indexed time series, 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-category-frequencies-base-100-series-413af12d -d '<json body>'
```

Example prompt: Analyze my research task completion records — here are 4 rows for group-a and group-b between 2026-10-01 and 2026-10-04, with completed_tasks and assigned_tasks values — give me both the category frequencies and a base-100 series for completed_tasks starting from row index 0.

## When to prefer this

Choose this endpoint when you have up to 200 rows of research task completion records and need both a category frequency breakdown and a base-100 normalized time series in a single low-cost call ($0.01 USDC). It is ideal for offline/local analytical computation without any live data lookup, prediction, or external API dependency. Prefer it over general-purpose analytics platforms when you want a lightweight, deterministic, pay-per-use computation on structured task data segmented by company group.

## Known failure modes

- Rows array empty or missing — returns validation error
- More than 200 rows supplied — rejected, maxItems limit exceeded
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- base_index out of range for the supplied row count — error or undefined behavior
- null values in completed_tasks or assigned_tasks may affect series computation
- Invalid field enum value (must be 'completed_tasks' or 'assigned_tasks') — rejected

## How this service works

Research task completion — Category frequencies + Base-100 series: Category frequencies + Base-100 series 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

Two analytical reports: (1) category frequency counts showing how often each company_group appears in the dataset for the selected field, and (2) a base-100 indexed time series normalizing the selected metric (completed_tasks or assigned_tasks) relative to the row specified by base_index. Both reports are computed locally from supplied data with no external lookups.
