How this service works
Business directory coverage — Category frequencies + Two-measure correlation: Category frequencies + Two-measure correlation for supplied business directory coverage records (listed_entities, verified_entities). 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 appears in the supplied rows, and (2) a two-measure correlation analysis quantifying the relationship between listed_entities and verified_entities across all supplied records. Up to 200 rows supported per call.
Example use cases
Directory verification rate analysis
“I have 50 rows of business directory data with dates from Q3 2025, company groups like 'retail', 'tech', and 'finance', and counts of listed versus verified entities for each. Can you compute how frequently each company group appears and tell me how strongly the verified count correlates with the listed count?”
Coverage audit across business segments
“Here are 120 records of our directory coverage — each has a date, a company_group label, and the number of listed_entities and verified_entities. Run the category frequency report to see which groups dominate, and compute the two-measure correlation to see if more listed entities means more verified ones.”
Monthly directory snapshot correlation check
“I've got 80 rows of business directory data for November 2025, split across company groups 'EMEA', 'APAC', and 'AMER'. Please run both the category frequency breakdown and the correlation between listed_entities and verified_entities so I can spot which region has the highest verification rate alignment.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-company-14-108?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have tabular business directory coverage data with listed and verified entity counts and need both a categorical frequency breakdown and a linear correlation between those two numeric measures in a single low-cost call. It is ideal for offline/batch analytical tasks on already-collected data (up to 200 rows) where no live lookup, prediction, or external data enrichment is needed.
Side effects
- Fewer than 1 row supplied — validation error
- More than 200 rows supplied — exceeds maximum item limit
- Missing required fields (row_id, company_group, date, listed_entities, verified_entities) — schema validation failure
- Invalid date format (not YYYY-MM-DD) — pattern mismatch error
- Numeric values outside ±1,000,000,000,000 range — schema bounds violation
- Insufficient variance in data — correlation may be undefined or return NaN
