How this service works
Sampling observations — Numeric distribution + Grouped numeric summary: Numeric distribution + Grouped numeric summary 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 numeric distribution of the chosen field (sample_value or sample_weight) across all supplied rows, and (2) a grouped numeric summary breaking down statistics by dataset_group. Both reports are generated locally from the supplied data with no external lookups.
Example use cases
Survey response distribution by segment
“I have 150 survey responses with numeric scores and respondent weights — can you compute the numeric distribution and a grouped summary by survey segment for the sample_value field so I can see how scores are spread across segments?”
Quality control sampling audit
“We collected 80 manufacturing samples across two production lines, each with a measurement value and a quality weight. Can you give me the numeric distribution and a grouped numeric summary by production line for the sample_value field?”
A/B test measurement analysis
“I've got 200 experiment observations from an A/B test — each row has a metric value, a weight, a date, and a group label. Can you run the numeric distribution and grouped numeric summary on the sample_value field so I can compare the two groups?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-analytics-15-071?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both a numeric distribution and a grouped numeric summary for sampling observations in a single low-cost call ($0.01 USDC). It is ideal when your data has group labels, weights, and dates and you want both overall distributional shape and per-group breakdowns without making two separate API calls. Prefer this over single-report endpoints when you need both report types simultaneously.
Side effects
- Rows array empty or missing — validation error requiring at least 1 row
- More than 200 rows submitted — rejected with maxItems exceeded error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Null values in sample_value or sample_weight may affect distribution completeness
- Invalid field enum value — must be 'sample_value' or 'sample_weight'
- Payment of 0.01 USDC not provided or declined — endpoint returns 402 payment required
