# Research Task Completion — Secondary-Measure Weighted Mean + Keyed Dataset Comparison

> Research Task Completion — Secondary-Measure Weighted Mean + Keyed Dataset Comparison 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 secondary-measure weighted mean and performs a keyed dataset comparison on up to 200 rows of research task completion records (completed_tasks, assigned_tasks), returning two independent analytical reports.

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-secondary-measure-weighted-mean-keyed-216c636e -d '<json body>'
```

Example prompt: Can you run a weighted mean and keyed comparison on our research task completion data? I have two datasets — both with up to 50 rows including completed_tasks and assigned_tasks by company group and date — and I want the analysis based on the completed_tasks field.

## When to prefer this

Choose this endpoint when you need both a weighted mean aggregation and a keyed dataset comparison for research task completion records in a single $0.01 call, with no need for external data enrichment, prediction, or live lookups. Best suited for batch analytical reporting on up to 200 rows of tabular task data with company group and date dimensions.

## Known failure modes

- Input rows array empty or missing (minItems: 1 violated)
- More than 200 rows submitted (maxItems: 200 exceeded)
- Invalid date format — must match YYYY-MM-DD pattern
- Missing required row fields: row_id, company_group, date, completed_tasks, or assigned_tasks
- Numeric values outside allowed range (-1e12 to 1e12)
- row_id exceeds 80 character limit or is empty
- field enum value not one of: completed_tasks, assigned_tasks

## How this service works

Research task completion — Secondary-measure weighted mean + Keyed dataset comparison: Secondary-measure weighted mean + Keyed dataset comparison 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) a secondary-measure weighted mean computed over the supplied rows for the chosen field (completed_tasks or assigned_tasks), and (2) a keyed dataset comparison highlighting differences between the primary and secondary (other) datasets, all computed locally without any external lookups or predictions.
