How this service works
Label review — Two-measure correlation + Keyed dataset comparison: Two-measure correlation + Keyed dataset comparison for supplied label review records (reviewed_records, changed_labels). 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 (e.g. Pearson/Spearman coefficient, p-value, sample size) between reviewed_records and changed_labels across the supplied rows; (2) a keyed dataset comparison report showing row-by-row matches, mismatches, and value differences between the primary (rows) and secondary (other) datasets, keyed on row_id. No external lookups or predictions are included.
Example use cases
Annotation quality correlation check
“I have 50 rows of label review data for January — can you compute the correlation between reviewed_records and changed_labels to see if busier review days produce more label changes? Here are the rows with date, row_id, dataset_group, reviewed_records, and changed_labels.”
Diff two label review dataset versions
“I've got two versions of my label review export — the original and a revised one, each up to 80 rows with row_id, dataset_group, date, reviewed_records, and changed_labels. Can you do a keyed comparison to show me exactly which rows changed between them?”
Multi-team label review audit
“We have label review stats from two annotation teams, group-a and group-b, across 40 dates. Run the two-measure correlation on reviewed_records vs changed_labels, and also compare the two teams' datasets row-by-row using row_id as the key so I can see where their numbers diverge.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-analytics-12-183?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both a statistical correlation between two numeric label-review metrics AND a structural diff between two versions of the same dataset in a single $0.01 call. It is ideal for annotation pipelines, ML data quality audits, and label change tracking where you want to understand both the quantitative relationship between review volume and label modifications, and identify exactly which keyed rows differ across two data snapshots — all without any external network lookups or predictions.
Side effects
- Empty or missing rows array returns validation error
- Row count exceeds 200 items — request rejected
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- Mismatched row_id keys between primary and secondary datasets reduce matched comparison coverage
- Null values in reviewed_records or changed_labels may reduce correlation sample size or produce NaN coefficient
- Missing required fields (row_id, dataset_group, date) cause row-level rejection
