How this service works
Sampling observations — Equal-width histogram + Date by category pivot: Equal-width histogram + 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 computed locally from the supplied rows: (1) an equal-width histogram showing frequency distribution of the selected field (sample_value or sample_weight) divided into the specified number of bins, and (2) a date-by-category pivot table cross-tabulating the selected field by date and dataset_group. Results cover up to 200 input rows with no external lookups or predictions.
Example use cases
Environmental monitoring data review
“I have 120 air quality sampling readings with measurement values and collection weights across two sensor groups, dated from January to March 2025. Can you run a histogram with 8 bins on the sample_value field and also pivot the data by date and sensor group so I can see patterns?”
Clinical trial sample distribution check
“I have 200 lab sample records from a clinical trial with sample_value and sample_weight columns, split between 'placebo' and 'active' groups and dated daily over Q1. Please generate the equal-width histogram with 5 bins and the date-by-category pivot on sample_value for both groups.”
Survey response weight analysis
“I've got 80 survey response rows, each with a weighted score as sample_weight and a raw response value as sample_value, grouped by 'region-east' and 'region-west' and dated weekly through 2025. Can you run both the histogram with 6 bins and the category date pivot on sample_weight?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-analytics-15-173?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need two simultaneous local analytics reports — a histogram and a date-by-category pivot — on sampling observation data (up to 200 rows) without any external data fetch, live lookup, or prediction. It is well-suited for exploratory data analysis, quality control, and scientific sampling workflows where you supply your own rows and want distribution and temporal-category breakdowns in a single low-cost call ($0.01 USDC).
Side effects
- More than 200 rows submitted — request rejected, trim input to 200 rows
- Invalid date format (not YYYY-MM-DD) causes row-level validation failure
- bins value outside 1–30 range causes rejection
- sample_value or sample_weight exceeds ±1 trillion causes schema error
- Empty rows array causes validation failure
- Missing required fields (row_id, dataset_group, date) causes rejection
