# Research Task Completion — Category Frequencies + Two-Measure Correlation

> Research Task Completion — Category Frequencies + Two-Measure Correlation 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: category frequency counts by company group and a correlation analysis between completed_tasks and assigned_tasks.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-two-measure-correlation-557a79bb -d '<json body>'
```

Example prompt: Can you analyze my research task completion data — I have up to 200 rows with fields like row_id, company_group, date, completed_tasks, and assigned_tasks — and give me both a category frequency breakdown by group and a correlation between the two task measures?

## When to prefer this

Choose this endpoint when you have tabular research task completion data with a categorical grouping field and two numeric measures, and you need both a frequency distribution by category and a pairwise correlation — all in a single $0.01 call covering up to 200 rows. Prefer this over generic BI tools when you want a lightweight, pay-per-use analytical micro-service with no setup, no data storage, and deterministic local computation.

## Known failure modes

- Fewer than 1 row supplied — minimum row count not met
- More than 200 rows submitted — exceeds maximum row limit
- Missing required fields (row_id, company_group, date, completed_tasks, assigned_tasks) in one or more rows
- Date field does not match YYYY-MM-DD pattern — rejected by schema validation
- Numeric values outside allowed range (-1,000,000,000,000 to 1,000,000,000,000) cause schema rejection
- All values for one measure are null — correlation cannot be computed

## How this service works

Research task completion — Category frequencies + Two-measure correlation: Category frequencies + Two-measure correlation 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) frequency counts of records per company_group category, and (2) a statistical correlation between the completed_tasks and assigned_tasks numeric measures, computed locally over up to 200 supplied rows without any external data lookup or prediction.
