# Schema Conformity — Grouped Numeric Summary + Equal-Width Histogram

> Schema Conformity — Grouped Numeric Summary + Equal-Width Histogram is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-17).

Generates two local analytical reports (grouped numeric summary and equal-width histogram) for schema conformity data tracking valid and checked records across dataset groups.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability schema-conformity-grouped-numeric-summary-equal-width-histogram-e4905375 -d '<json body>'
```

Example prompt: Summarize this schema conformity data for the valid_records field into a grouped numeric summary and a 10-bin histogram — I have about 50 rows across two dataset groups, group-a and group-b, with dates ranging from 2024-01-01 to 2024-03-31.

## When to prefer this

Choose this endpoint when you need both a grouped statistical summary and a histogram distribution report for schema conformity data (valid_records and checked_records) in a single low-cost call. It is ideal for data quality analysts who want quick offline analytics on up to 200 conformity records without any external API dependency, prediction, or live data lookup. Prefer this over general analytics tools when the data fits the schema conformity domain with dataset_group and date dimensions.

## Known failure modes

- More than 200 rows submitted — request rejected due to maxItems constraint
- Invalid date format (not YYYY-MM-DD) causes validation error
- Missing required fields (row_id, dataset_group, date, valid_records, checked_records) causes schema rejection
- bins value outside 1–30 range causes validation failure
- Empty rows array causes minItems validation error
- Null values in numeric fields may affect summary statistics output

## How this service works

Schema conformity — Grouped numeric summary + Equal-width histogram: Grouped numeric summary + Equal-width histogram for supplied schema conformity records (valid_records, checked_records). 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 breaking down valid_records or checked_records statistics by dataset_group, and (2) an equal-width histogram of the selected field with up to 30 configurable bins — both computed locally on the supplied data without any external lookups.
