# Schema Conformity Numeric Distribution & Equal-Width Histogram

> Schema Conformity Numeric Distribution & 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 2026-10-15).

Computes numeric distribution statistics and an equal-width histogram for schema conformity metrics (valid_records, checked_records) across up to 200 rows of supplied data.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-numeric-distribution-equal-width-histogram-2b38d0bd -d '<json body>'
```

Example prompt: Can you run a numeric distribution and equal-width histogram on my schema conformity data — I have up to 50 rows with valid_records and checked_records fields — use 10 bins and analyze the valid_records field?

## When to prefer this

Choose this endpoint when you need fast, local statistical analysis of schema conformity metrics — specifically numeric distribution and histogram reports — on datasets up to 200 rows, without requiring external data sources or live lookups. Ideal for data quality audits, ETL monitoring, and compliance checks where you already have valid_records and checked_records tabular data and want two analytical views in a single $0.01 call.

## Known failure modes

- Missing required fields (row_id, date, valid_records, checked_records) cause validation errors
- Rows exceeding 200 items are rejected
- Invalid date format (non YYYY-MM-DD) fails schema validation
- Bins value outside 1–30 range is rejected
- Null values in the target field may affect distribution completeness
- Invalid field enum value (not valid_records or checked_records) causes rejection

## How this service works

Schema conformity — Numeric distribution + Equal-width histogram: Numeric distribution + 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 for the specified numeric field: (1) a numeric distribution summary (mean, min, max, percentiles, etc.) and (2) an equal-width histogram with configurable bin count showing frequency counts per bin — both computed locally from the supplied row data without any external lookup.
