# Schema Conformity — Numeric Interval Filter + Equal-Width Histogram

> Schema Conformity — Numeric Interval Filter + 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 2026-10-18).

Filters schema conformity records by a numeric interval and generates an equal-width histogram for up to 200 rows, producing two analytical reports in one call.

## 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-interval-filter-equal-width-histogram-83d82423 -d '<json body>'
```

Example prompt: Filter my schema conformity records where valid_records falls between 0 and 500, then bucket them into 10 equal-width bins and show me the histogram — here are my rows: row-1 (group-a, 2024-01-01, valid=120, checked=200), row-2 (group-b, 2024-01-02, valid=340, checked=400), row-3 (group-a, 2024-01-03, valid=600, checked=800).

## When to prefer this

Choose this endpoint when you need both a numeric range filter AND a histogram distribution in a single cheap call ($0.01 USDC) on schema conformity data (valid_records, checked_records). Ideal for data quality pipelines needing quick statistical summaries without external dependencies. Prefer over manual computation when you have up to 200 conformity rows and want two reports simultaneously.

## Known failure modes

- Fewer than 1 row provided — minItems:1 validation error
- More than 200 rows submitted — maxItems:200 validation error
- Invalid date format in any row — pattern mismatch error
- bins value outside 1–30 range — schema validation failure
- minimum greater than maximum — may produce empty filter results with no error
- null values in the selected numeric field — rows may be excluded from interval filter silently
- field enum value not 'valid_records' or 'checked_records' — validation error

## How this service works

Schema conformity — Numeric interval filter + Equal-width histogram: Numeric interval filter + 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 reports: (1) a filtered subset of the input rows whose selected numeric field (valid_records or checked_records) falls within the specified [minimum, maximum] interval, and (2) an equal-width histogram dividing that numeric range into the requested number of bins with counts of how many rows fall in each bin.
