minimumnumberYesThe inclusive lower bound for number or integer values.

How to use this schema

Use minimum for prices, quantities, pagination limits, scores, and thresholds. Pair it with maximum when a numeric field has a valid range.

Version support and combinations

This keyword or pattern is commonly supported across modern JSON Schema workflows. Check your validator for Draft-04, Draft-07, 2019-09, and 2020-12 behavior before relying on newer composition or conditional features.

Common combination: pair this reference with type, required, and properties so validation errors are specific enough for API clients and form users.
