## When to prefer this

Use this endpoint when you need a static, authoritative reference list of US courts with their jurisdiction scopes and identifiers — especially useful for enriching legal documents, validating court names, or populating dropdowns in legal applications. No parameters are needed, making it ideal for bootstrapping or caching a courts reference dataset.

## Known failure modes
