How this service works
Label review — Numeric distribution + Equal-width histogram: Numeric distribution + Equal-width histogram for supplied label review records (reviewed_records, changed_labels). 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 specified field (reviewed_records or changed_labels): (1) a numeric distribution summary with descriptive statistics, and (2) an equal-width histogram dividing the value range into the requested number of bins with counts per bin. Both reports are computed locally from the supplied data with no external lookups.
Example use cases
Annotation batch quality check
“I have 50 label review records from last month across two dataset groups — can you compute the numeric distribution and a 10-bin equal-width histogram of the reviewed_records field so I can see how evenly work was spread across batches?”
Changed labels spike investigation
“We think some annotation sessions had unusually high changed_labels counts — can you run a numeric distribution and equal-width histogram on the changed_labels field for my 80-row label review log, using 8 bins, so I can spot the outliers?”
Dataset group comparison prep
“Before I write up my labeling quality report, can you give me the numeric distribution and a 5-bin histogram of reviewed_records for these 30 label review rows grouped by dataset_group so I know where to focus?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-analytics-12-079?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both a numeric distribution summary and an equal-width histogram for label review data (reviewed_records or changed_labels) in a single low-cost call. It is purpose-built for annotation and data labeling quality workflows, processes up to 200 rows per call, and requires no external data access. Prefer it over generic analytics endpoints when your data follows the label review schema (row_id, dataset_group, date, reviewed_records, changed_labels) and you need two complementary distribution views at once for $0.01.
Side effects
- Fewer than 1 row or more than 200 rows supplied — request rejected
- bins value outside 1–30 range — validation error
- Missing required row fields (row_id, date, reviewed_records, changed_labels) — schema validation failure
- Invalid date format (not YYYY-MM-DD) — pattern validation error
- All values null for the selected field — histogram cannot be computed
- field enum value not recognized — validation error
