How this service works
Join coverage — Duplicate key report + Two-measure correlation: Duplicate key report + Two-measure correlation for supplied join coverage records (matched_rows, source_rows). 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 duplicate key report identifying any repeated row_id values across the submitted join coverage records, and (2) a two-measure correlation analysis quantifying the statistical relationship between matched_rows and source_rows. Both reports are computed locally on the supplied data with no external lookups.
Example use cases
ETL pipeline join quality audit
“I have 50 rows from my nightly ETL join output with matched_rows and source_rows values per dataset group and date — can you check for duplicate keys and tell me how correlated those two measures are?”
Data warehouse join coverage check
“My data warehouse team ran a join coverage report across two tables and I got back 120 records with row IDs, groups, dates, matched counts, and source counts — please run a duplicate key report and a two-measure correlation on all of them.”
Debugging low match rate anomalies
“I suspect some row IDs are duplicated in my join results for group-a between 2026-09-01 and 2026-09-30, and I want to see if there's a correlation between how many rows matched vs how many were in the source — can you run both reports on my 30 records?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-analytics-09-066?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both a duplicate key diagnostic and a two-measure statistical correlation on join coverage data in a single call, especially when working with up to 200 rows of matched_rows/source_rows pairs and you need a fast, offline computation with no external data dependencies.
Side effects
- Fewer than 1 row submitted — validation error
- More than 200 rows submitted — request rejected
- Missing required fields (row_id, dataset_group, date, matched_rows, source_rows) — schema validation failure
- date field not in YYYY-MM-DD format — pattern validation error
- numeric values outside ±1,000,000,000,000 range — validation error
- All matched_rows or source_rows are null — correlation cannot be computed
