How this service works
Sampling observations — Category frequencies + Daily sum series: Category frequencies + Daily sum 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 computed locally from the supplied rows: (1) category frequencies showing how often each dataset_group value appears, and (2) a daily sum time series showing totals of the selected field (sample_value or sample_weight) aggregated by date. Both reports are derived purely from the submitted data with no external lookups.
Example use cases
Survey response frequency analysis
“I collected 150 survey responses with category labels and response scores — can you give me a frequency table of how often each category appears and a daily sum of scores over the past month?”
Weighted inventory sample aggregation
“I have daily inventory sampling records with item groups, measured values, and sampling weights — run a category frequency breakdown and a daily total series on sample_value for me across these 80 rows.”
Clinical trial sample group summary
“Here are 120 clinical trial observation records with patient group labels, measurement values, and sample weights — can you produce a frequency count by group and a daily summed series of the measurement values?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-analytics-15-102?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have up to 200 tabular sampling observation records and need two quick analytical outputs — category frequency counts and a daily aggregated sum series — without needing external data lookups, predictions, or professional assessments. It is cost-effective at $0.01 USDC for both reports together and is ideal for lightweight, self-contained statistical summaries of survey, sampling, or time-stamped observational data.
Side effects
- Submitting more than 200 rows will be rejected due to the maxItems constraint
- Missing required fields (row_id, dataset_group, date, sample_value, sample_weight) will cause validation errors
- Dates not matching the YYYY-MM-DD pattern will fail schema validation
- Non-numeric or out-of-range values for sample_value or sample_weight (beyond ±1,000,000,000,000) will be rejected
- Empty rows array (minItems:1 not met) will return an error
- Payment failure (insufficient USDC) will prevent the call from completing
