How this service works
Business directory coverage — Base-100 series + Two-measure correlation: Base-100 series + 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 analytical reports: (1) a Base-100 index series showing how the selected field (listed_entities or verified_entities) evolves relative to the chosen base row, and (2) a two-measure Pearson-style correlation between listed_entities and verified_entities across all supplied rows. Both reports are computed locally from the submitted data with no external lookups.
Example use cases
Monthly directory growth benchmarking
“I have monthly business directory data for two regions — North and South — tracking listed and verified entity counts over 12 months. Can you index the listed_entities field to base-100 starting from month 0 and also give me the correlation between listed and verified entities across all rows?”
Verification rate trend analysis
“I want to understand how our business verification rate tracks against total listings over the past quarter. I have 90 daily rows per company group with listed_entities and verified_entities values — can you run a base-100 series on verified_entities using row 0 as the baseline and compute the two-measure correlation for me?”
Multi-group directory coverage audit
“We have coverage data for three company groups — Alpha, Beta, and Gamma — across 60 dates. Can you produce a base-100 index for listed_entities (starting from index row 0) and show the correlation between listed and verified entities so I can see which group has the best verification coverage trend?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-company-14-165?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both a time-indexed Base-100 normalization and a pairwise correlation report on business directory coverage metrics (listed vs verified entities) in a single paid call. Ideal for agents working with structured directory audit data that is already available locally, where no live data lookup, prediction, or external enrichment is needed. At $0.01 USDC for two reports on up to 200 rows, it is cost-effective for batch analytical passes over directory snapshots.
Side effects
- Fewer than 1 row submitted — validation error
- More than 200 rows submitted — rejected with maxItems error
- base_index value out of range for supplied rows — index error
- Missing required fields (row_id, date, listed_entities, verified_entities) — schema validation failure
- Non-date-formatted string in date field — pattern validation error
- Null values in both measure columns — correlation undefined or NaN result
