# Research Task Completion — Category Frequencies + IQR Outlier Flags

> Research Task Completion — Category Frequencies + IQR Outlier Flags is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-21).

Computes category frequencies and IQR-based outlier flags for research task completion records (completed_tasks, assigned_tasks) across up to 200 rows, returning 2 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-category-frequencies-iqr-outlier-flags-11cdcfb8 -d '<json body>'
```

Example prompt: Analyze my research task completion records — I have rows with company_group, date, completed_tasks, and assigned_tasks for up to 200 entries — and give me category frequencies plus IQR outlier flags on the completed_tasks field.

## When to prefer this

Choose this endpoint when you need lightweight, local statistical analysis on task completion datasets up to 200 rows — specifically IQR outlier detection and category frequency summaries — without needing live lookups, ML predictions, or external enrichment. Ideal for research operations teams doing quick data quality checks or distribution analysis on completed vs assigned task records at very low cost ($0.01 per call).

## Known failure modes

- Fewer than 1 row supplied — minimum 1 row required
- More than 200 rows supplied — maxItems exceeded, request rejected
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- Missing required fields (row_id, company_group, date) causes rejection
- Null values in both numeric fields may reduce outlier detection reliability
- Invalid field enum value (not 'completed_tasks' or 'assigned_tasks') causes error

## How this service works

Research task completion — Category frequencies + IQR outlier flags: Category frequencies + IQR outlier flags 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 2 independent analytical reports: (1) category frequency counts grouped by company_group or date for the selected field, and (2) IQR-based outlier flags per row indicating which records fall outside the interquartile range for the chosen field (completed_tasks or assigned_tasks). No external data is used; analysis runs on supplied rows only.
