# Training Compliance Equal-Width Histogram and Two-Measure Correlation

> Training Compliance Equal-Width Histogram and 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 2026-10-26).

Computes an equal-width histogram and a two-measure correlation report for training compliance data (completed_courses and assigned_courses) from up to 200 supplied 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 training-compliance-equal-width-histogram-and-two-measure-correlation-cf3a13a1 -d '<json body>'
```

Example prompt: I have training compliance records for my teams — can you run an equal-width histogram with 10 bins on completed_courses and also compute the correlation between completed_courses and assigned_courses for these 50 rows of data?

## When to prefer this

Choose this endpoint when you have up to 200 rows of training compliance records and need both a distributional view (histogram) and a pairwise relationship measure (correlation) in a single low-cost call. It is ideal for HR analytics, L&D reporting, and compliance auditing workflows where no external data lookup or prediction is needed — just fast local statistical analysis of your own supplied data.

## Known failure modes

- Exceeding 200 rows returns a validation error
- Missing required fields (row_id, date, completed_courses, assigned_courses) causes row-level rejection
- Invalid date format (non-YYYY-MM-DD) triggers a schema validation error
- Requesting more than 30 bins or fewer than 1 bin fails schema validation
- Null values in numeric fields may reduce effective sample size for correlation
- Payment of 0.01 USDC not received results in HTTP 402 and no computation

## How this service works

Training compliance — Equal-width histogram + Two-measure correlation: Equal-width histogram + Two-measure correlation for supplied training compliance records (completed_courses, assigned_courses). 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 computed locally against the supplied data: (1) an equal-width histogram breaking the chosen field (completed_courses or assigned_courses) into the specified number of bins with counts per bin, and (2) a two-measure correlation report quantifying the linear relationship between completed_courses and assigned_courses across all supplied rows.
