How this service works
Vendor evaluation — Equal-width histogram + Secondary-measure weighted mean: Equal-width histogram + Secondary-measure weighted mean 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: (1) an equal-width histogram showing the frequency distribution of the selected score field across the specified number of bins, and (2) a secondary-measure weighted mean where one score field is weighted by the other, computed locally over up to 200 supplied vendor evaluation rows.
Example use cases
Vendor scorecard distribution analysis
“I have 120 vendor evaluation rows with supplied_score and maximum_score fields. Can you bucket the supplied_score values into 8 equal-width bins and show me how many vendors fall in each range?”
Weighted mean for procurement ranking
“For these 75 vendor records grouped by company_group, calculate the weighted mean of supplied_score where maximum_score is the secondary weight — I want to see which groups are performing best on average.”
Dual-report vendor performance review
“Run both the equal-width histogram (5 bins) and the secondary-measure weighted mean on my 200-row vendor evaluation dataset using maximum_score as the field, so I can compare score spread and weighted averages in one go.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-company-10-172?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both a histogram distribution view and a weighted mean statistic on vendor evaluation scores in a single API call, without requiring any external data lookups or live predictions. Ideal for batch analytical reporting on up to 200 pre-collected vendor records where you want two complementary statistical perspectives for $0.01 USDC.
Side effects
- More than 200 rows submitted — request rejected due to row limit
- Missing required fields (row_id, supplied_score, maximum_score, date, company_group) cause validation errors
- Invalid bin count outside 1–30 range
- Null values in score fields may affect weighted mean computation
- Malformed date strings not matching YYYY-MM-DD pattern
