How this service works
Vendor evaluation — Equal-width histogram + Two-measure correlation: Equal-width histogram + Two-measure correlation for supplied vendor evaluation records (supplied_score, maximum_score). 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 computed locally: (1) an equal-width histogram showing the frequency distribution of the selected field (supplied_score or maximum_score) across the specified number of bins, and (2) a correlation analysis between the supplied_score and maximum_score measures across the provided vendor evaluation rows, with no external lookups or live data.
Example use cases
Vendor scoring distribution audit
“I have 120 vendor evaluation records from Q3 with supplied_score and maximum_score values — can you generate an equal-width histogram with 10 bins on the supplied_score field so I can see how our vendors are distributed across performance tiers?”
Supplier score correlation check
“For our annual procurement review, I need to know how correlated the supplied_score is with the maximum_score across my 80 vendor records — can you run the two-measure correlation report on that data?”
Multi-group vendor performance analysis
“I have vendor evaluation data split across three company groups — group-alpha, group-beta, and group-gamma — with 60 rows each. Can you run both the equal-width histogram (5 bins) and the correlation analysis on the supplied_score and maximum_score fields?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-company-10-171?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, offline statistical analysis of vendor evaluation data specifically involving distribution histograms and two-measure score correlation — no internet access, prediction, or third-party enrichment needed. Ideal for procurement teams analyzing up to 200 vendor records at low cost ($0.01 per call covering both reports).
Side effects
- More than 200 rows submitted — request rejected with validation error
- Missing required fields (row_id, supplied_score, maximum_score, date, company_group) — schema validation failure
- Null values in both score fields may reduce correlation validity
- bin count outside 1–30 range causes validation error
- Malformed date strings not matching YYYY-MM-DD pattern are rejected
