How this service works
Join coverage — Grouped numeric summary + Secondary-measure weighted mean: Grouped numeric summary + Secondary-measure weighted mean 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 grouped numeric summary (e.g. count, min, max, mean, std dev) broken down by dataset_group for the selected field, and (2) a secondary-measure weighted mean where the chosen field is weighted by the other measure — all computed locally from the supplied data, with no external lookups.
Example use cases
ETL pipeline join quality audit
“I have daily join coverage logs for three dataset groups over the past month, with source_rows and matched_rows per day. Can you group them and give me a numeric summary plus the weighted mean of matched_rows so I can spot which groups have poor join rates?”
Data warehouse coverage comparison
“Here are 50 join coverage records across four dataset groups from our data warehouse pipeline. Please compute the grouped numeric summary and secondary-measure weighted mean for source_rows so I can compare coverage completeness across groups.”
QA report on merge operation results
“We ran a merge operation and I have before-and-after row counts as matched_rows and source_rows for each dataset group. Can you summarize the numeric distribution by group and calculate the weighted mean of matched_rows to put in our QA report?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-analytics-09-096?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have join coverage data (matched_rows, source_rows) already in hand and need both a grouped numeric summary and a weighted mean computed together in a single call for up to 200 rows. It is ideal for data engineers, QA teams, and analytics pipelines that generate join metrics and want a fast, cost-effective ($0.01 USDC for 2 reports) local computation without any external data enrichment or prediction.
Side effects
- Missing required fields (row_id, dataset_group, date, matched_rows, source_rows) cause validation errors
- Date strings not matching YYYY-MM-DD pattern are rejected
- Submitting more than 200 rows exceeds the maxItems limit and is rejected
- Null values in matched_rows or source_rows may affect weighted mean computation
- Empty rows array (minItems: 1 violated) returns an error
- Invalid field enum value (not 'matched_rows' or 'source_rows') causes schema rejection
