How this service works
Vendor evaluation — Category frequencies + Two-measure correlation: Category frequencies + 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 independent analytical reports: (1) a category frequency table showing how often each company_group value appears in the input rows, and (2) a two-measure correlation report quantifying the statistical relationship between supplied_score and maximum_score across all provided rows. Both reports are computed locally with no external lookups.
Example use cases
Vendor scoring pattern analysis
“Here are our Q3 vendor evaluation records for groups A, B, and C — each row has a supplied_score and maximum_score. Can you tell me how frequently each vendor group appears and whether the supplied scores are correlated with the maximum scores?”
Procurement audit score correlation
“I need to audit our procurement vendor data. I have about 80 rows with vendor group names, evaluation dates, and two numeric score columns. Can you produce a frequency table by vendor category and a correlation report between the two scores?”
Supplier performance benchmarking
“We scored 120 suppliers across three company groups — can you analyze how many evaluations each group has and run a correlation between their supplied scores and the maximum possible scores to see how consistently they perform relative to the ceiling?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-company-10-108?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have vendor evaluation tabular data with categorical groupings and two numeric score measures, and you need both a frequency distribution by category and a correlation statistic between the two measures in a single low-cost call. Prefer it over general-purpose analytics tools when you want a bundled, pay-per-use statistical micro-service with no infrastructure setup, handling up to 200 rows at $0.01 per call.
Side effects
- Fewer than 1 row or more than 200 rows submitted — rejected with validation error
- Missing required fields (row_id, company_group, date, supplied_score, maximum_score) on any row — error returned
- Date strings not matching YYYY-MM-DD format — pattern validation failure
- Null values in both score columns for all rows may degrade or invalidate correlation computation
- Payment of 0.01 USDC not completed — 402 Payment Required response
