# Research Task Completion — Daily Sum Series + Base-100 Series

> Research Task Completion — Daily Sum Series + Base-100 Series 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).

Computes a daily sum time series and a base-100 indexed series for supplied research task completion data (completed_tasks and assigned_tasks), producing 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-base-100-series-6dce5aea -d '<json body>'
```

Example prompt: Can you run a daily sum series and base-100 series on our research task completion data — I have 4 rows across group-a and group-b from Oct 1–4 2026, tracking completed_tasks, and I want the base index set to row 0?

## When to prefer this

Choose this endpoint when you have up to 200 rows of research task completion records and need both a daily aggregated sum series and a base-100 normalized index series in a single low-cost call ($0.01 USDC). It is ideal for offline/batch analytical use cases where no live data lookup, prediction, or external enrichment is needed — just fast local computation on supplied data.

## Known failure modes

- Missing required fields (row_id, date, company_group, completed_tasks, assigned_tasks) cause validation errors
- Submitting more than 200 rows exceeds the maxItems limit and is rejected
- Invalid date format (non-YYYY-MM-DD) fails pattern validation
- base_index out of range (>= number of rows) causes computation failure
- Null values in the selected metric field may produce gaps in the series
- Payment failure or insufficient USDC balance prevents the call from completing

## How this service works

Research task completion — Daily sum series + Base-100 series: Daily sum series + Base-100 series 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 daily sum series aggregating the selected metric (completed_tasks or assigned_tasks) by date, and (2) a base-100 indexed series normalizing the same metric relative to the specified base_index row, both computed locally from the supplied row data without any external lookup.
