# Research Task Completion — Category Frequencies + Keyed Dataset Comparison

> Research Task Completion — Category Frequencies + 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 2026-10-17).

Analyzes research task completion records (completed_tasks, assigned_tasks) to produce two reports: category frequency distribution and a keyed row-by-row comparison between two supplied datasets.

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-keyed-dataset-comparison-a21940aa -d '<json body>'
```

Example prompt: I have two batches of research task records for our company groups — can you run a category frequency breakdown on the main batch and then compare it row-by-row against the second batch to spot differences in completed_tasks and assigned_tasks?

## When to prefer this

Choose this endpoint when you have up to 200 rows of research task completion records and need both a categorical frequency distribution and a keyed comparison between two versions of the same dataset in a single $0.01 call. It is ideal for periodic audits comparing planned vs. actual task completion across company groups, or for diffing two time-period snapshots without needing a full data warehouse. Prefer alternatives if you need more than 200 rows, real-time lookups, predictive analytics, or a different combination of report types (other sibling endpoints on the same provider offer different report pairings).

## Known failure modes

- More than 200 rows supplied — request will be rejected or truncated
- Missing required fields (row_id, company_group, date, completed_tasks, assigned_tasks) cause validation errors
- Date values not matching YYYY-MM-DD pattern will fail schema validation
- row_id values not present in both datasets will result in unmatched rows in the comparison report
- Null numeric values in completed_tasks or assigned_tasks may affect aggregation accuracy
- Empty rows array (minItems:1 violated) will return an error

## How this service works

Research task completion — Category frequencies + Keyed dataset comparison: Category frequencies + 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 category frequencies report showing how often each company_group (or other categorical field) appears in the primary dataset, and (2) a keyed dataset comparison report that matches rows by row_id between the primary and secondary datasets and highlights differences in completed_tasks and assigned_tasks values. Both reports are computed locally from supplied data with no external lookups.
