# Research Task Completion — Duplicate Key Report + Equal-Width Histogram

> Research Task Completion — Duplicate Key Report + 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 2026-10-17).

Analyzes up to 200 research task completion records to produce a duplicate key report and an equal-width histogram for completed_tasks or assigned_tasks fields.

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-duplicate-key-report-equal-width-histogram-e107c527 -d '<json body>'
```

Example prompt: Check my research task completion records for duplicate keys and also show me an equal-width histogram with 10 bins for completed_tasks — here are up to 200 rows with row_id, company_group, date, completed_tasks, and assigned_tasks fields.

## When to prefer this

Choose this endpoint when you need both a duplicate key audit and a histogram distribution analysis on research task completion data (completed_tasks, assigned_tasks) in a single $0.01 USDC call. It is ideal for data quality checks before downstream reporting or aggregation, covering up to 200 rows entirely from supplied data with no external dependencies. Prefer alternatives if you need only one of the two reports, need more than 200 rows, require live data lookup, or need different analytical operations such as correlation or time-series aggregation.

## Known failure modes

- Fewer than 1 row or more than 200 rows supplied — request rejected
- bins value outside 1–30 range — validation error
- Missing required fields (row_id, company_group, date, completed_tasks, assigned_tasks) on any row — schema error
- Invalid date format (not YYYY-MM-DD) — pattern validation failure
- Numeric values outside ±1,000,000,000,000 range — schema error
- Payment not included or insufficient — x402 payment required error

## How this service works

Research task completion — Duplicate key report + Equal-width histogram: Duplicate key report + 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 independent analytical reports: (1) a duplicate key report identifying rows with repeated key combinations, and (2) an equal-width histogram showing the frequency distribution of the selected numeric field (completed_tasks or assigned_tasks) across the specified number of bins (1–30). Both reports are computed locally from the supplied data with no external lookups.
