How this service works
Sampling observations — Category frequencies + Numeric interval filter: Category frequencies + Numeric interval filter 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 category frequency table showing how often each dataset_group value appears in the supplied rows, and (2) a filtered subset of records where the selected field (sample_value or sample_weight) falls within the specified minimum and maximum interval bounds. Results are computed locally on the supplied data with no external lookups.
Example use cases
Survey response frequency by group
“I have survey sampling data with group labels and response scores. Can you run category frequency counts across my dataset groups and also filter responses where sample_value is between 10 and 50? Here are the rows: row-1, 2026-10-01, group-a, 10, 1; row-2, 2026-10-02, group-b, 20, 2; row-3, 2026-10-03, group-a, 15, 3; row-4, 2026-10-04, group-b, 30, 4.”
Quality control sample range filtering
“For my QC sampling data, I need to know how often each product category appears and which samples fall within an acceptable sample_value range of 5 to 95. I have 8 rows across two groups — can you give me both reports at once?”
Weighted observation distribution audit
“I'm auditing weighted sampling observations from two cohorts. Please compute the category frequencies for dataset_group and filter the sample_weight field to the interval between 1 and 10. I'll pass you up to 200 rows of records with row_id, date, dataset_group, sample_value, and sample_weight.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-analytics-15-101?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both a categorical frequency distribution and a numeric range filter on the same sampling dataset in a single API call. It is ideal for small-to-medium datasets (up to 200 rows) where you want two complementary statistical reports cheaply ($0.01 USDC) without connecting to external data sources. Prefer alternatives if you need time-series aggregation, weighted means, histograms, or deduplication — sibling endpoints on market.datapackvibe.com handle those operations.
Side effects
- More than 200 rows submitted — exceeds maxItems limit
- Missing required fields (row_id, dataset_group, date, sample_value, sample_weight) on any row
- Date field not in YYYY-MM-DD format
- Numeric values outside allowed range (-1e12 to 1e12)
- Minimum greater than maximum in interval filter — may return empty result set
- Empty rows array — minItems 1 not satisfied
