Query parameters

limit (optional): Page size (1–100, default 100).
after (optional): Keyset cursor — return the page after this row (next page).
before (optional): Keyset cursor — return the page before this row (prev page).

default_version_id (optional): Shorthand: filter where defaultVersionId equals this value.
system (optional): Shorthand: filter where system equals this value.
created_by (optional): Shorthand: filter where createdBy equals this value.
runtime_user_id (optional): Shorthand: filter where runtimeUserId equals this value.
retention_tier (optional): Shorthand: filter where retentionTier equals this value.
