# Research Task Completion — Numeric Row Ordering + Equal-Width Histogram

> Research Task Completion — Numeric Row Ordering + Equal-Width Histogram is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-21).

Generates two local analytical reports — a numeric row ordering and an equal-width histogram — for research task completion data (completed_tasks, assigned_tasks) across 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-numeric-row-ordering-equal-width-histogram-84020c5e -d '<json body>'
```

Example prompt: Can you rank my research task completion rows by completed_tasks and also generate an equal-width histogram with 5 bins for those values? I have records for group-a and group-b from October 2026 — here's the data: row-1 (group-a, 2026-10-01, 10 completed, 1 assigned), row-2 (group-b, 2026-10-02, 20 completed, 2 assigned), row-3 (group-a, 2026-10-03, 15 completed, 3 assigned), row-4 (group-b, 2026-10-04, 30 completed, 4 assigned).

## When to prefer this

Choose this endpoint when you need two simultaneous local-only analytical reports — numeric sorting and equal-width histogram — on research task completion data without any external lookups, predictions, or live data enrichment. It is ideal for offline batch analysis of up to 200 task records where you want to understand both rank order and frequency distribution of completed or assigned tasks in a single $0.01 call.

## Known failure modes

- More than 200 rows supplied — request rejected or truncated
- Invalid date format (not YYYY-MM-DD) in any row causes validation error
- bins parameter outside 1–30 range causes rejection
- Missing required fields (row_id, company_group, date, completed_tasks, assigned_tasks) in any row triggers schema error
- All values for the chosen field are null — histogram cannot be computed
- Numeric values outside ±1,000,000,000,000 range rejected

## How this service works

Research task completion — Numeric row ordering + Equal-width histogram: Numeric row ordering + Equal-width histogram 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 numeric row ordering of the supplied records sorted by the chosen field (completed_tasks or assigned_tasks), and (2) an equal-width histogram showing bin boundaries and the count of records falling into each bin. No external data is fetched; all computation is performed locally on the supplied rows.
