# Research Task Completion — Daily Sum Series + Keyed Dataset Comparison

> Research Task Completion — Daily Sum Series + 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 by computing a daily sum time series and comparing two keyed datasets side-by-side, returning two analytical reports for up to 200 rows.

## 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-daily-sum-series-keyed-dataset-comparison-bd3172cc -d '<json body>'
```

Example prompt: I have two sets of research task completion records (up to 200 rows each) with columns for date, company_group, completed_tasks, and assigned_tasks — can you compute the daily sum series for completed_tasks and also compare the two datasets row by row to spot differences?

## When to prefer this

Choose this endpoint when you need both a daily time series aggregation AND a keyed row-by-row comparison of two research task completion datasets in a single $0.01 call. It is ideal for offline/batch analytical workflows where no live data lookup, prediction, or external action is needed, and your data fits within 200 rows. Prefer it over separate aggregation and diff tools when you want two coordinated reports on the same task completion schema in one shot.

## Known failure modes

- Missing required fields (row_id, company_group, date, completed_tasks, assigned_tasks) will cause validation errors
- More than 200 rows submitted will exceed the row limit and be rejected
- Invalid date format (not YYYY-MM-DD) will fail pattern validation
- Null or out-of-range numeric values beyond ±1,000,000,000,000 will be rejected
- Empty rows array will fail minItems:1 constraint
- Payment failure or insufficient USDC balance will prevent execution

## How this service works

Research task completion — Daily sum series + Keyed dataset comparison: Daily sum series + 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 analytical reports: (1) a daily sum time series aggregating the selected field (completed_tasks or assigned_tasks) by date, and (2) a keyed dataset comparison highlighting row-level differences between the primary and secondary datasets. Both reports are computed locally with no external lookups.
