How this service works
Sampling observations — Duplicate key report + Equal-width histogram: Duplicate key report + Equal-width histogram 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 duplicate key report identifying any row_id values that appear more than once across the submitted records, and (2) an equal-width histogram showing the frequency distribution of the selected numeric field (sample_value or sample_weight) divided into the specified number of bins (1–30). Both reports are computed locally from the supplied data with no external lookups.
Example use cases
Survey data quality check
“I've got 80 survey response rows with sample_value and sample_weight columns — can you check them for duplicate row IDs and show me how the sample_value is distributed across 8 equal-width bins?”
Weighted sample distribution analysis
“Here are 150 observation records from my field study. I need a duplicate key report to catch any repeated entries, plus a histogram with 5 bins on the sample_weight column so I can see the spread.”
Pre-analysis data validation for research dataset
“Before I hand this sampling dataset off to my stats team, can you run it through a duplicate key check and give me a 15-bin equal-width histogram on sample_value? There are about 200 rows total.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-analytics-15-064?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both a duplicate key check and a distribution histogram on sampling observation data in a single cheap call ($0.01 USDC). It is ideal for pre-analysis data quality workflows on datasets up to 200 rows where you want to detect repeated row IDs and understand the numeric distribution of sample_value or sample_weight without any external data enrichment or live lookups.
Side effects
- More than 200 rows submitted — request will be rejected or truncated
- bins value outside 1–30 range — validation error
- Missing required fields (row_id, dataset_group, date, sample_value, sample_weight) on any row — schema validation failure
- date field not matching YYYY-MM-DD pattern — format error
- All sample_value or sample_weight entries are null — histogram cannot be computed
- Payment not included or insufficient USDC — x402 payment required error
