How this service works
Sampling observations — Category frequencies + Equal-width histogram: Category frequencies + Equal-width histogram 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 independent analytical reports: (1) category frequency counts showing how many records fall in each dataset_group category, and (2) an equal-width histogram partitioning the chosen numeric field (sample_value or sample_weight) into the specified number of bins, with counts per bin — all computed locally on the supplied data with no external lookups.
Example use cases
Survey response distribution analysis
“I've collected 80 survey responses with numeric scores and weights — can you give me category frequencies by survey group and a 5-bin equal-width histogram of the sample_value field so I can see how scores are distributed?”
Quality control sampling histogram
“I have 200 manufacturing measurement samples across two product lines, each with a sample_value and a sample_weight — please compute category frequencies by product line and split the measurements into 8 equal-width bins.”
Market research weight distribution
“Here are 120 market research observations with sample values and sample weights across three regions — give me the category frequency counts by region and a 6-bin histogram of the sample_weight field.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-analytics-15-106?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need two quick statistical summaries — category frequencies and a histogram — computed purely on supplied data without any external data access, predictions, or professional assessments. It is ideal for small-to-medium datasets (up to 200 rows) where you want both group-level counts and a numeric distribution in a single low-cost call ($0.01 USDC). Prefer it over general-purpose analytics services when you want a simple, reproducible, serverless statistical computation on sampling observation data with weighted records.
Side effects
- More than 200 rows submitted — request rejected with row count error
- bins value outside 1–30 range — validation error
- Missing required fields (row_id, dataset_group, date, sample_value, sample_weight) — schema validation failure
- sample_value or sample_weight outside ±1,000,000,000,000 — rejected
- All sample_value entries are null — histogram cannot be computed
- Invalid date format (not YYYY-MM-DD) — pattern validation error
