# Research Task Completion — Grouped Numeric Summary + Secondary-Measure Weighted Mean

> Research Task Completion — Grouped Numeric Summary + Secondary-Measure Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Computes a grouped numeric summary and a secondary-measure weighted mean for supplied research task completion records (completed_tasks, assigned_tasks) across up to 200 rows, returning two independent analytical reports.

## 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-grouped-numeric-summary-secondary-measure-6506e92b -d '<json body>'
```

Example prompt: Can you run a grouped numeric summary and a secondary-measure weighted mean on my research task completion data? I have records for group-a and group-b across four dates, with completed_tasks and assigned_tasks values — use completed_tasks as the primary field and give me both reports.

## When to prefer this

Choose this endpoint when you have tabular research task completion records grouped by company or team and need both a grouped numeric summary and a weighted mean across two measures in a single $0.01 call. It is ideal for offline/batch analytical use cases where you supply your own data and need fast, local statistical computation without any external data fetching or prediction.

## Known failure modes

- Missing required fields (row_id, company_group, date, completed_tasks, assigned_tasks) cause validation errors
- Supplying more than 200 rows exceeds the row limit and will be rejected
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- Null values in both primary and secondary fields for a group may produce undefined weighted mean
- Invalid field enum value (not 'completed_tasks' or 'assigned_tasks') causes rejection

## How this service works

Research task completion — Grouped numeric summary + Secondary-measure weighted mean: Grouped numeric summary + Secondary-measure weighted mean 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 independent analytical reports: (1) a grouped numeric summary of the selected primary field (completed_tasks or assigned_tasks) broken down by company_group, and (2) a secondary-measure weighted mean using the other field as weights. Results are derived entirely from the supplied rows with no external data lookups.
