How this service works
Sampling observations — Equal-width histogram + Keyed dataset comparison: Equal-width histogram + Keyed dataset comparison 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) an equal-width histogram showing bin boundaries and frequency/weight counts for the chosen field across the supplied rows, and (2) a keyed dataset comparison that aligns rows by row_id between the main and comparison datasets to surface differences in sample_value or sample_weight. No external data is fetched; all analysis is performed locally on the supplied records.
Example use cases
A/B test sample distribution comparison
“I ran an A/B test and have two sets of sampling observations, each with about 80 rows tagged as 'control' and 'treatment'. Can you build a 10-bin equal-width histogram of sample_value and compare the two datasets so I can see how the distributions differ?”
Survey response weight analysis
“I have 150 survey responses with numeric scores and associated weights. Can you histogram the sample_value field into 8 equal-width bins and compare the weighted responses across my two respondent groups so I can spot any distributional differences?”
QC sampling batch before-after comparison
“We pulled 200 quality control samples before and after a process change. Can you run a 5-bin equal-width histogram on the sample_value column and do a keyed comparison between the pre-change and post-change datasets to see what shifted?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-analytics-15-174?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both a distribution histogram and a side-by-side keyed comparison of two sets of sampling observation records in a single API call. It is purpose-built for weighted sample data with group labels and dates, supports up to 200 rows, and delivers two reports for the price of one. Prefer this over general-purpose analytics APIs when your data matches the sample_value/sample_weight schema and you need the combined histogram + comparison output without setting up a full analytics platform.
Side effects
- More than 200 rows submitted — request will be rejected or truncated
- Missing required fields (row_id, dataset_group, date, sample_value, sample_weight) cause row-level errors
- Invalid date format (not YYYY-MM-DD) causes validation failure
- bin count outside 1–30 range causes schema validation error
- Null values in sample_value or sample_weight may affect histogram bin calculations
- Payment of 0.01 USDC not completed results in 402 response
