# Research Task Completion — Base-100 Series + Equal-Width Histogram

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

Generates two analytical reports (Base-100 indexed time series and equal-width histogram) from user-supplied research task completion data (completed_tasks, assigned_tasks) for up to 200 rows.

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-base-100-series-equal-width-histogram-fc3018ef -d '<json body>'
```

Example prompt: I have 50 rows of research task completion records with company group, date, completed_tasks, and assigned_tasks — can you run a Base-100 indexed series starting at row 0 and an equal-width histogram with 8 bins on the completed_tasks field?

## When to prefer this

Choose this endpoint when you have tabular research task completion records (up to 200 rows) and need both a normalized Base-100 time series and a histogram distribution report in a single low-cost call. It is ideal for quickly benchmarking task completion rates against a baseline and visualizing frequency distributions without setting up a local analytics environment.

## Known failure modes

- More than 200 rows supplied — request rejected
- base_index out of bounds for the supplied row count
- bins value outside 1–30 range — validation error
- Required row fields (row_id, company_group, date, completed_tasks, assigned_tasks) missing — schema validation failure
- date field not in YYYY-MM-DD format — parsing error
- Payment not provided or insufficient — x402 payment required response

## How this service works

Research task completion — Base-100 series + Equal-width histogram: Base-100 series + 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 Base-100 indexed series showing how completed_tasks or assigned_tasks values evolve relative to a chosen baseline row, and (2) an equal-width histogram with the specified number of bins showing the frequency distribution of the chosen field across all supplied rows. Both reports are computed locally from the supplied data with no external lookups.
