Sampling Observations — Numeric Distribution + Keyed Dataset Comparison
x402
Sampling Observations — Numeric Distribution + Keyed Dataset Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).
Analyzes up to 200 sampling observation rows (sample_value, sample_weight) to produce two reports: a numeric distribution analysis and a keyed dataset comparison between two supplied datasets.

How this service works
Sampling observations — Numeric distribution + Keyed dataset comparison: Numeric distribution + 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 structured analytical reports: (1) a numeric distribution report summarizing statistical properties of the selected field (sample_value or sample_weight) across the supplied rows, and (2) a keyed dataset comparison report contrasting the primary dataset against the 'other' dataset by matching row keys, highlighting differences in values across dataset groups.
Example use cases
A/B sampling experiment comparison
“I ran two rounds of sampling — group-a and group-b — and I have 150 rows per dataset with sample_value and sample_weight recorded. Can you compare the two datasets by key and show me the numeric distribution of sample_value for each?”
Quality control weighted sample audit
“I need to audit our weighted sampling data from October 2026 — I have 80 rows with sample_value and sample_weight fields across two production groups. Please run a numeric distribution report and compare the two keyed datasets to spot differences.”
Survey response distribution analysis
“Here are two batches of survey response scores — 120 rows each — with sample_value as the score and sample_weight as the respondent weight. Can you analyze the numeric distribution and do a keyed comparison between the two batches?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-analytics-15-084?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need two complementary analytical reports on the same sampling dataset in a single call — specifically a numeric distribution and a keyed cross-dataset comparison — and your data fits within 200 rows with sample_value and sample_weight fields. It is well-suited for statistical QA, A/B test analysis, or before/after sampling comparisons where you supply both datasets locally and need no external data lookup or prediction.
Side effects
- Missing required fields (row_id, dataset_group, date, sample_value, sample_weight) returns validation error
- Exceeding 200 rows in either dataset triggers a row limit rejection
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- Null values in sample_value or sample_weight may reduce the usable row count for distribution stats
- Empty rows array returns an error due to minItems:1 constraint
- field enum value outside ['sample_value','sample_weight'] causes rejection
