# Research Task Completion — Duplicate Key Report + Two-Measure Correlation

> Research Task Completion — Duplicate Key Report + Two-Measure Correlation 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 rows of research task completion records to produce two reports: a duplicate key report and a Pearson/Spearman correlation between completed_tasks and assigned_tasks.

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-two-measure-correlation-ad48bd0d -d '<json body>'
```

Example prompt: Can you run a duplicate key check and a correlation analysis between completed_tasks and assigned_tasks on my research task completion data? I have about 50 rows with row_id, company_group, date, completed_tasks, and assigned_tasks columns — I'll paste them in.

## When to prefer this

Choose this endpoint when you need both duplicate key detection and a two-measure correlation in a single paid call on up to 200 rows of task completion records, saving you the cost of two separate API calls. Ideal for lightweight data quality and statistical checks on research datasets where no live data lookup or external enrichment is needed. Not suited for datasets exceeding 200 rows, multi-measure correlations, or predictive modeling.

## Known failure modes

- Fewer than 1 row submitted — validation error
- More than 200 rows submitted — request rejected or truncated
- Missing required fields (row_id, date, company_group) — schema validation error
- Non-date-formatted date strings — pattern validation failure
- Null values in both measure columns preventing correlation computation
- Payment not received or insufficient USDC — 402 response

## How this service works

Research task completion — Duplicate key report + Two-measure correlation: Duplicate key report + Two-measure correlation 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 any rows sharing the same key fields (e.g. row_id, or company_group+date combinations), and (2) a two-measure correlation report showing the statistical relationship between completed_tasks and assigned_tasks across the supplied rows. Both reports are computed locally using shared analytical engines on the submitted data with no external lookups.
