# Contact Record Quality: Two-Measure Correlation + Keyed Dataset Comparison

> Contact Record Quality: Two-Measure Correlation + Keyed Dataset Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Analyzes contact record quality data by computing correlation between checked_records and duplicate_records, and comparing two keyed datasets row-by-row, for up to 200 rows.

## 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 contact-record-quality-two-measure-correlation-keyed-dataset-comparison-95364da6 -d '<json body>'
```

Example prompt: I have two batches of contact record quality data — each up to 200 rows with fields like row_id, company_group, date, checked_records, and duplicate_records — can you run both a two-measure correlation between checked and duplicate counts and a keyed comparison across the two datasets to see where they diverge?

## When to prefer this

Choose this endpoint when you have two sets of contact record quality data (with checked_records and duplicate_records fields) and need both a statistical correlation between those two measures AND a keyed row-by-row comparison between the two datasets in a single $0.01 call. It is ideal for offline, batch-style quality audits where no live data lookup, external enrichment, or prediction is needed — just local analytical computation on your supplied data of up to 200 rows.

## Known failure modes

- Empty or missing rows array returns an error or empty report
- Rows exceeding 200-item limit are rejected
- Malformed date strings not matching YYYY-MM-DD pattern cause validation failure
- Missing required fields (row_id, company_group, date, checked_records, duplicate_records) cause row-level rejection
- Null values in numeric fields may reduce correlation validity
- Mismatched row_ids between primary and comparison datasets reduce keyed comparison coverage

## How this service works

Contact record quality — Two-measure correlation + Keyed dataset comparison: Two-measure correlation + Keyed dataset comparison for supplied contact record quality records (checked_records, duplicate_records). 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 two-measure correlation report showing the statistical relationship between checked_records and duplicate_records across all supplied rows; (2) a keyed dataset comparison report aligning rows from the primary and secondary datasets by row_id to highlight differences in checked_records and duplicate_records values. No external lookups or predictions are made; all analysis is computed locally from the supplied data.
