## When to prefer this

Use this endpoint when you need to discover which runtime versions are available for a specific language before submitting code for execution. It's the right choice when dynamically selecting a language version for a code execution job or validating compatibility before running code.

## Known failure modes

- Unsupported or unrecognized language name returns empty versions array or error
- Missing required 'language' field returns a 400 validation error
- Language string typo or wrong casing may return no results
- Service unavailability returns a 5xx error
