_sort_fieldsstring nullable

Comma delimited fields to sort with. Prefixing '-' to a field will force a sort in descending order.

id_formatstring nullable

Optional. If set to 'legacy', MP identifier fields in the response are returned in the form 'mp-149'. If set to 'alpha', they are returned in the padded AlphaID form 'mp-aaaaaaft'. If omitted (or set to any other value), identifiers are returned in their stored form. This is a purely cosmetic transform; query inputs accept either shape regardless.
