How this service works
Sampling observations — Daily sum series + Two-measure correlation: Daily sum series + Two-measure correlation 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 computed locally from the supplied data: (1) a daily sum time series aggregating the selected field (sample_value or sample_weight) by date, and (2) a two-measure correlation report quantifying the relationship between sample_value and sample_weight across the provided rows. Covers up to 200 input records.
Example use cases
Environmental monitoring trend analysis
“I have 150 daily water quality sampling records with sample_value for pollutant concentration and sample_weight for sample volume — can you generate the daily sum series and correlation report between these two measures?”
Survey response weighted aggregation
“Here are 80 survey response rows with sample_value as the response score and sample_weight as the respondent's demographic weight, dated across October 2026 — please run the daily sum series and two-measure correlation analysis on them.”
Quality control batch summarization
“I've got 200 factory inspection samples across two groups, group-a and group-b, with daily sample_value readings and sample_weight per batch — run the daily sum time series and correlation report so I can spot trends.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-analytics-15-141?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both a daily sum time series and a correlation between two numeric measures (sample_value and sample_weight) computed from supplied observation data in a single low-cost call. It is ideal for small to medium datasets (up to 200 rows) where you already have the data locally and want quick statistical summaries without external lookups, predictions, or professional assessments.
Side effects
- More than 200 rows submitted — request exceeds maxItems limit
- Missing required fields (row_id, dataset_group, date, sample_value, sample_weight) cause validation errors
- Invalid date format (not YYYY-MM-DD) fails pattern validation
- Numeric values outside ±1,000,000,000,000 range are rejected
- Payment not completed — x402 protocol requires 0.01 USDC per call
