How this service works
Aggregation checks — Two-measure correlation + Secondary-measure weighted mean: Two-measure correlation + Secondary-measure weighted mean for supplied aggregation checks records (source_sum, aggregate_sum). 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 coefficient between source_sum and aggregate_sum across the supplied rows, and (2) a weighted mean of the specified field (source_sum or aggregate_sum). Results are computed locally with no external lookup or prediction.
Example use cases
Financial reconciliation correlation check
“I've got 80 rows of monthly source-vs-aggregate financial totals by region — run the two-measure correlation on source_sum and aggregate_sum, and also give me the weighted mean for source_sum.”
Data pipeline quality validation
“My ETL pipeline produces source_sum and aggregate_sum for each batch — can you analyze the statistical correlation between them across these 200 rows and compute the weighted mean of aggregate_sum to spot systematic drift?”
Multi-group aggregation audit
“I have audit data with source_sum and aggregate_sum split across group-a and group-b over the past quarter — compute the two-measure correlation and weighted mean for aggregate_sum so I can see if the groups are in agreement.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-analytics-17-181?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both a correlation analysis and a weighted mean computed together in a single paid call on up to 200 rows of aggregation check data (source_sum vs aggregate_sum). It is purpose-built for data reconciliation and aggregation auditing workflows where you want two statistical reports for a single $0.01 USDC fee, with no external data fetching or prediction.
Side effects
- rows array empty or missing — minItems:1 violated
- more than 200 rows supplied — maxItems exceeded
- date field does not match YYYY-MM-DD pattern
- source_sum or aggregate_sum out of range (±1,000,000,000,000)
- row_id or dataset_group exceeds maxLength of 80 characters
- field enum value not one of source_sum or aggregate_sum
- insufficient numeric data (all nulls) to compute correlation or weighted mean
