# Schema Conformity Analytics: Two-Measure Correlation + Keyed Dataset Comparison

> Schema Conformity Analytics: 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 2026-10-14).

Computes two independent analytical reports — a two-measure correlation (valid_records vs checked_records) and a keyed dataset comparison — on up to 200 rows of schema conformity data.

## 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 schema-conformity-analytics-two-measure-correlation-keyed-dataset-7e23449e -d '<json body>'
```

Example prompt: Can you run a two-measure correlation and keyed dataset comparison on my schema conformity data? I have two sets of up to 200 rows each, with row_id, dataset_group, date, valid_records, and checked_records — here's the primary set: [{"row_id":"r1","dataset_group":"group-a","date":"2024-01-01","valid_records":95,"checked_records":100},...] and the secondary set for comparison.

## When to prefer this

Choose this endpoint when you need both a statistical correlation between two numeric conformity measures AND a keyed comparison between two datasets in a single $0.01 USDC call, without needing live data lookup, external enrichment, or predictive modeling. Ideal for data quality pipelines, schema migration validation, and ETL monitoring workflows where you supply your own conformity records (up to 200 rows).

## Known failure modes

- Missing required fields (row_id, dataset_group, date, valid_records, checked_records) causes validation error
- Exceeding 200 rows per dataset results in rejection
- Invalid date format (not YYYY-MM-DD) triggers schema error
- Null values in both valid_records and checked_records may degrade correlation quality
- Payment failure (insufficient USDC) blocks endpoint access

## How this service works

Schema conformity — Two-measure correlation + Keyed dataset comparison: Two-measure correlation + Keyed dataset comparison for supplied schema conformity records (valid_records, checked_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 quantifying the statistical relationship between valid_records and checked_records across the supplied rows, and (2) a keyed dataset comparison report showing row-by-row or group-level differences between the primary and secondary datasets. All computation is performed locally on the supplied data with no external lookups.
