# Schema Conformity Analytics: Equal-Width Histogram + Keyed Dataset Comparison

> Schema Conformity Analytics: Equal-Width Histogram + Keyed Dataset Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-18).

Generates two analytical reports (equal-width histogram and keyed dataset comparison) on schema conformity data (valid_records, checked_records) for up to 200 rows.

## 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-analytics-equal-width-histogram-keyed-dataset-7cfa42f7 -d '<json body>'
```

Example prompt: Analyze my schema conformity data — I have two datasets of up to 50 rows each with valid_records and checked_records fields, and I want an equal-width histogram with 10 bins on valid_records plus a keyed comparison between the two datasets to see where they differ.

## When to prefer this

Choose this endpoint when you need both a distributional view (histogram) and a direct row-by-row comparison of schema conformity metrics in a single $0.01 call, without needing real-time data, predictions, or external enrichment. Ideal for data quality teams doing batch analysis on up to 200 records of valid_records and checked_records.

## Known failure modes

- More than 200 rows supplied — request rejected or truncated
- Missing required fields (row_id, dataset_group, date, valid_records, checked_records) on any row — validation error
- bins value outside 1–30 range — schema validation failure
- Invalid date format (not YYYY-MM-DD) — pattern validation error
- Mismatched row_ids between primary and comparison datasets — comparison report may show unmatched keys
- Null numeric values may be excluded from histogram computation

## How this service works

Schema conformity — Equal-width histogram + Keyed dataset comparison: Equal-width histogram + Keyed dataset comparison 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

Two independent analytical reports: (1) an equal-width histogram showing the frequency distribution of the chosen field (valid_records or checked_records) across the specified number of bins, and (2) a keyed dataset comparison that matches rows from the primary and secondary datasets by row_id and surfaces differences in the numeric fields. Both reports are computed locally without external lookups.
