# Data Validation Results – Two-Measure Correlation

> Data Validation Results – 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 2026-10-20).

Computes a two-measure correlation (e.g., checked_records vs. failed_records) over up to 200 typed data validation records, returning a local descriptive analytics report with no enrichment or forecasting.

## 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 data-validation-results-two-measure-correlation-9d5d0c58 -d '<json body>'
```

Example prompt: Can you run a two-measure correlation on my data validation results? Here are my records — each has a date, a rule name, checked_records, and failed_records — I want to see how strongly those two measures are correlated across the dataset.

## When to prefer this

Choose this endpoint when you need a quick, local, descriptive two-measure correlation between checked_records and failed_records in a bounded dataset of up to 200 data validation records, without needing external data enrichment, forecasting, or multi-measure analysis. Ideal for data quality teams running lightweight statistical checks on validation pipeline outputs at low cost ($0.01 USDC per report).

## Known failure modes

- Fewer than 1 row submitted — returns validation error
- More than 200 rows submitted — request rejected due to maxItems constraint
- Missing required fields (row_id, rule, date, checked_records, failed_records) — schema validation error
- Invalid date format (not YYYY-MM-DD) — pattern validation failure
- Numeric values outside allowed range — schema rejection
- Insufficient variance in either measure to compute meaningful correlation — may return null or zero correlation

## How this service works

Data validation results - Two-measure correlation: Two-measure correlation for Data validation results. Up to 200 supplied typed records. Local descriptive analytics; no enrichment or forecast. One of 25 new profiles across 20 shared operations in this industry. 0.01 USDC includes one bounded two-measure correlation report.

## Output

Returns a bounded two-measure correlation report summarizing the statistical relationship between checked_records and failed_records across the supplied validation rows. Includes a correlation coefficient and descriptive analytics derived locally from the submitted dataset, with no external enrichment or forecasting.
