How this service works
Job listing inventories — Base-100 series + Two-measure correlation: Base-100 series + Two-measure correlation for supplied job listing inventories records (listing_count, duplicate_listings). 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 for the supplied rows: (1) a Base-100 indexed series showing each row's selected measure (listing_count or duplicate_listings) normalized relative to the chosen base row, and (2) a correlation report measuring the linear relationship between listing_count and duplicate_listings across all supplied rows.
Example use cases
Indexing job listing growth by company
“I have weekly job listing counts and duplicate listing counts for three company groups over 12 weeks — can you normalize the listing_count into a Base-100 series starting from the first week so I can compare growth across groups?”
Detecting duplicate listing inflation
“Run a two-measure correlation between listing_count and duplicate_listings on my dataset of 80 rows across different company groups so I can see whether higher listing volumes are associated with more duplicates.”
Benchmarking recruiter inventory changes
“I want to benchmark how our job listing inventory has changed relative to our starting point in January — please compute a Base-100 index on the listing_count field using row 0 as the base, and also correlate it with duplicate_listings.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-company-13-165?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have pre-collected job listing inventory data (listing_count and duplicate_listings) and need offline statistical analysis — specifically a Base-100 normalization series and a pairwise correlation — without any live data lookup, external enrichment, or prediction. Best suited for up to 200 rows of historical or batch snapshot data where you want indexed trend comparison and correlation in a single low-cost call.
Side effects
- Fewer than 1 row supplied — request rejected
- More than 200 rows supplied — exceeds limit
- base_index references a row index that doesn't exist in the submitted array
- Missing required fields (row_id, date, listing_count, duplicate_listings) on any row
- Date strings not matching YYYY-MM-DD pattern
- Base row value is zero, causing division-by-zero in the Base-100 calculation
- Null values in both measures preventing correlation computation
