How this service works
Sampling observations — Duplicate key report + Secondary-measure weighted mean: Duplicate key report + Secondary-measure weighted mean 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 independent analytical reports: (1) a duplicate key report identifying any repeated row_id values across the submitted rows, and (2) a weighted mean of the selected field (sample_value or sample_weight) using the paired weight column — all computed locally on up to 200 supplied rows with no external lookups.
Example use cases
Survey data duplicate detection
“I have a batch of 50 survey observation records each with a row_id, dataset_group, date, sample_value, and sample_weight — can you scan them for any duplicate row IDs and give me the weighted mean of sample_value at the same time?”
Weighted mean for field comparison
“Run a weighted mean on the sample_weight field across my 120 sampling observation rows — also flag any duplicate keys you find. Here are the rows with their row_ids, dates, groups, values, and weights.”
Pre-analysis data quality check
“Before I proceed with my analysis, can you check these 80 sampling records for duplicate row IDs and compute the weighted average of sample_value using sample_weight? I want both reports in one shot.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-analytics-15-067?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both duplicate key detection and a weighted mean statistic in a single API call on up to 200 sampling observation rows. It is ideal for pre-analysis data quality checks on survey or sampling datasets where you want to validate row uniqueness and compute a weighted aggregate without setting up a local analytics pipeline. Prefer this over separate tools when the dataset fits within 200 rows and you want a cost-effective ($0.01 USDC) combined report.
Side effects
- Fewer than 1 row submitted — validation error
- More than 200 rows submitted — exceeds maxItems limit
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- sample_value or sample_weight out of allowed range (-1e12 to 1e12) — rejected
- Missing required fields (row_id, dataset_group, date) — request rejected
- All weights are zero — weighted mean may be undefined or return error
- Payment not provided or insufficient — x402 payment required
