How this service works
Sampling observations — Two-measure correlation + Date by category pivot: Two-measure correlation + Date by category pivot for supplied sampling observations records (sample_value, sample_weight). 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 analytical reports: (1) a two-measure correlation result quantifying the statistical relationship between sample_value and sample_weight across the supplied rows, and (2) a date-by-category pivot table summarizing the selected field (sample_value or sample_weight) broken down by date and dataset_group. All computation is performed locally on the supplied data with no external lookups.
Example use cases
Survey response correlation analysis
“I've collected 150 survey responses with a numeric score and a response weight per respondent, grouped by cohort, with dates — can you check how correlated the score and weight are, and also show me a pivot of scores by date and cohort?”
Environmental sampling cross-tabulation
“I have 80 environmental sample readings with sample_value and sample_weight recorded by site group and collection date. Run a correlation between the two measures and give me a pivot table breaking down values by date and group.”
Quality control batch review
“Here are 200 QC lab sample records with a measurement value and a batch weight per row, organized by product group and test date. I need both a correlation report between the measurement and weight, and a date-by-group pivot summary.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-analytics-15-182?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have tabular sampling data with two numeric measures (sample_value and sample_weight) and want both a correlation analysis and a date-by-category pivot in a single low-cost call (0.01 USDC). It is ideal for datasets up to 200 rows where no external lookup, prediction, or live data is needed — pure local computation on supplied records.
Side effects
- Fewer than 1 row supplied — request rejected
- More than 200 rows supplied — exceeds maximum item limit
- Missing required fields (row_id, dataset_group, date, sample_value, sample_weight) in any row — validation error
- Date fields not matching YYYY-MM-DD pattern — schema validation failure
- Numeric values outside ±1,000,000,000,000 range — rejected
- Payment of 0.01 USDC not included or declined — 402 response
