How this service works
Join coverage — Base-100 series + Two-measure correlation: Base-100 series + 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 analytical reports: (1) a base-100 indexed time series for the selected field (matched_rows or source_rows), anchored at the specified base_index row, showing relative change across all supplied rows; and (2) a two-measure correlation report quantifying the statistical relationship between matched_rows and source_rows across the dataset. Both reports are computed locally on the supplied data with no external lookups.
Example use cases
ETL pipeline join quality audit
“I have daily join coverage records from my ETL pipeline for October — each row has a date, a dataset_group, source_rows, and matched_rows. Can you index matched_rows to base-100 starting from day 0 and tell me how strongly matched_rows and source_rows are correlated across all 30 rows?”
Multi-group match rate trend comparison
“I've got 50 rows of join coverage data split across two dataset groups, with dates from 2025-01-01 to 2025-02-19. Please produce a base-100 series for source_rows indexed from row 0 and also compute the two-measure correlation between source_rows and matched_rows so I can see if both groups move together.”
Data reconciliation baseline benchmarking
“My reconciliation team exported 120 rows of matched vs source row counts by date and group. Can you normalize the matched_rows field to a base-100 index starting at position 0, and then run a correlation report between matched_rows and source_rows to see if coverage quality tracks with data volume?”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-analytics-09-165?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have up to 200 rows of join coverage data (matched_rows and source_rows per date and dataset group) and need both a base-100 normalized trend series and a correlation analysis between the two measures in a single $0.01 call. It is ideal for data engineers or analysts auditing ETL pipeline join quality over time without requiring live lookups or external data sources.
Side effects
- More than 200 rows submitted — endpoint accepts a maximum of 200 rows
- Missing required fields (row_id, date, matched_rows, source_rows, dataset_group) on any row — validation error
- date field not matching YYYY-MM-DD pattern — schema validation failure
- base_index out of range (must be 0–199 and within actual row count) — index error
- All matched_rows or source_rows values are null — insufficient data for correlation
- Malformed JSON payload — request rejected before processing
