How this service works
Sampling observations — Grouped numeric summary + Trailing mean series: Grouped numeric summary + Trailing mean series 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 grouped numeric summary breaking down statistics (e.g. mean, count, min, max) for sample_value or sample_weight across dataset_group categories, and (2) a trailing mean series showing rolling window averages of the chosen field across the date-ordered rows. Both reports are computed locally with no external lookups.
Example use cases
Survey response trend analysis
“I have 120 rows of survey response data with sample values and weights grouped into three cohorts — can you compute a grouped numeric summary and a trailing mean series with window 5 on the sample_value field so I can see trends by cohort?”
Quality control sample monitoring
“We collect daily quality control measurements across two production lines — can you run a grouped numeric summary plus a trailing mean series with window 10 on our sample_weight readings for the last 180 rows so we can spot drift?”
A/B test segment statistics
“I've got 200 rows of A/B test observations split into two groups — can you give me grouped numeric stats and a rolling mean series with a window of 4 on the sample_value column so I can compare segment performance over time?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-analytics-15-090?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both a grouped categorical summary and a rolling/trailing mean time series from the same batch of sampling observation data in a single paid call. It is ideal for survey, quality-control, or experimental data with explicit group labels and date-ordered records. Prefer this over single-report endpoints when you want two complementary views (cross-sectional + temporal) for the price of one call.
Side effects
- Fewer than 1 row or more than 200 rows provided — request rejected
- Window size larger than the number of rows — trailing mean series may be incomplete or error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- sample_value or sample_weight outside allowed range (±1,000,000,000,000) — rejected
- Missing required fields (row_id, dataset_group, date) — validation error
- Payment of 0.01 USDC not completed — 402 Payment Required response
