x402
Sampling Observations — String Normalisation + Two-Measure Correlation is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-24).
Performs string normalisation and two-measure correlation analysis on up to 200 sampling observation rows (sample_value, sample_weight), returning two independent analytical reports.

How this service works
Sampling observations — String normalisation + Two-measure correlation: String normalisation + 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
Two independent analytical reports: (1) a string normalisation result for the supplied observation records and (2) a two-measure correlation analysis between sample_value and sample_weight, computed locally against the provided rows (up to 200). No external lookups or predictions are made.
Example use cases
Weighted survey sample correlation
“I have 150 survey responses with sample values and sample weights across several demographic groups — can you run string normalisation and two-measure correlation on them so I can see how the two measures relate?”
Quality control batch analysis
“We've got 80 QC observations from this week across two production lines, each with a measurement value and a weighting factor — please run the two-report analysis: string normalisation and correlation between the two measures.”
Academic dataset correlation check
“I need to check the correlation between sample_value and sample_weight in my dataset of 60 labelled observations spanning October 2025 — can you normalise the strings and give me the two-measure correlation report?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-analytics-15-033?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined string normalisation and two-measure (value/weight) correlation analysis delivered as two reports in a single low-cost call, without requiring live data lookups or external model predictions. Ideal for small-to-medium datasets (up to 200 rows) where local computation suffices and cost predictability matters ($0.01 USDC flat).
Side effects
- More than 200 rows supplied — request will be rejected due to maxItems constraint
- Missing required fields (row_id, dataset_group, date, sample_value, sample_weight) cause validation errors
- Date fields not matching YYYY-MM-DD pattern will fail schema validation
- Null values in sample_value or sample_weight may affect correlation computation quality
- Payment not processed — x402 payment of 0.01 USDC required per call
