How this service works
Vendor evaluation — Grouped numeric summary + Trailing mean series: Grouped numeric summary + Trailing mean series for supplied vendor evaluation records (supplied_score, maximum_score). 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 showing aggregate statistics (e.g. count, mean, min, max) of the chosen field broken down by company_group, and (2) a trailing mean series showing rolling averages of the chosen field over the specified window, both computed entirely from the supplied rows without any external data lookup.
Example use cases
Quarterly vendor performance summary
“I have 150 vendor evaluation records from Q3 with supplied_score and maximum_score for about 8 supplier groups. Can you group them and give me a numeric summary plus a trailing mean series with a window of 4 on the supplied_score field?”
Comparing two supplier groups over time
“I've got evaluation data for group-a and group-b vendors across 60 rows dated this year. Can you compute the grouped stats and a 5-period rolling mean on supplied_score so I can see how each group is trending?”
Procurement scoring trend for a single vendor cohort
“Run a grouped numeric summary and trailing mean with window size 7 on my procurement vendor scores — I have 90 rows with company_group, date, supplied_score, and maximum_score — and use maximum_score as the field to analyze.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-company-10-090?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have up to 200 vendor evaluation records with group labels and want both a grouped aggregate summary and a rolling mean time series in a single low-cost ($0.01 USDC) call, with no need for external data enrichment or live scoring — purely local analytical computation on your supplied data.
Side effects
- Fewer than 1 row or more than 200 rows submitted — request rejected
- Missing required fields (row_id, company_group, date, supplied_score, maximum_score) on any row — validation error
- Window size larger than number of rows — trailing mean series may be empty or incomplete
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Null values in the selected numeric field — may reduce effective sample size in statistics
