x402
Sampling Observations — Numeric Row Ordering + Equal-Width Histogram is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).
Analyzes up to 200 sampling observation rows (sample_value, sample_weight) by producing two local reports: a numeric row ordering and an equal-width histogram.

How this service works
Sampling observations — Numeric row ordering + Equal-width histogram: Numeric row ordering + 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 for the supplied rows: (1) a numeric row ordering ranking each record by the selected field (sample_value or sample_weight), and (2) an equal-width histogram partitioning the field values into the specified number of bins (1–30) with frequency/weight counts per bin. No external lookups or predictions are made; all analysis is performed locally on the submitted data.
Example use cases
Distribution check for lab sample readings
“I have 120 lab sample records with values and weights — can you sort them numerically and build a 15-bin equal-width histogram on the sample_value field so I can see how the readings are distributed?”
Quality control weight spread analysis
“Run an ordering and a 10-bin histogram on my 80 QC observations using sample_weight as the field — I need to understand the spread of weights across the dataset.”
Experiment cohort frequency breakdown
“I've got 200 experiment observations from three dataset groups and I want a ranked ordering plus an equal-width histogram with 20 bins on sample_value so I can spot any gaps or clusters.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-analytics-15-118?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, offline statistical analysis of a small-to-medium dataset (up to 200 rows) of weighted sample observations and want both a ranked ordering and a histogram in one call at minimal cost ($0.01 USDC). It is ideal when no external data enrichment, prediction, or live lookup is required — just deterministic local computation on data you supply directly.
Side effects
- More than 200 rows submitted — request rejected
- bins value outside 1–30 range — validation error
- Missing required fields (row_id, sample_value, sample_weight, date, dataset_group) — schema error
- All sample_value or sample_weight fields are null — histogram cannot be computed
- Payment not included or insufficient USDC — 402 payment required response
- Invalid date format (must match YYYY-MM-DD) — schema validation error
