How this service works
Supplier qualification — Equal-width histogram + Two-measure correlation: Equal-width histogram + Two-measure correlation for supplied supplier qualification records (checked_criteria, met_criteria). 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) an equal-width histogram with configurable bin count showing frequency distribution of the selected numeric field (checked_criteria or met_criteria), and (2) a two-measure correlation report quantifying the statistical relationship between checked_criteria and met_criteria across all supplied rows.
Example use cases
Supplier audit distribution analysis
“I've got 80 supplier qualification rows with checked_criteria scores — can you build an equal-width histogram with 8 bins on checked_criteria and also show me the correlation between checked_criteria and met_criteria so I can see how well suppliers are performing?”
Procurement team criteria compliance check
“We're reviewing 200 supplier records from last quarter. Can you compute the correlation between how many criteria were checked versus how many were actually met, and also give me a 5-bin histogram of the met_criteria field?”
Vendor scoring spread and alignment report
“Here are 60 vendor qualification entries — run a 6-bin equal-width histogram on the met_criteria field and tell me the two-measure correlation between checked_criteria and met_criteria so I know if vendors who check more criteria actually meet more of them.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-company-02-171?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both a histogram and a correlation report on supplier qualification data in a single call at minimal cost ($0.01 USDC for both reports). Ideal for batch offline analysis of up to 200 rows where no live lookup, prediction, or external data enrichment is needed — pure local statistical computation on your own supplied records.
Side effects
- Fewer than 1 or more than 200 rows submitted — request rejected
- Null values in checked_criteria or met_criteria may reduce effective sample size for correlation
- Invalid date format (not YYYY-MM-DD) causes row-level validation failure
- bins parameter outside 1–30 range is rejected
- Missing required fields (row_id, company_group, date, checked_criteria, met_criteria) cause row rejection
- All-null values in the target field make histogram computation undefined
