Filter the list. Each clause is written field:operator:value, and multiple clauses are separated by a semicolon (;) — not a comma, which the sort parameter uses. Clauses are combined with AND; grouping and OR are not supported here. Supported fields: isActive (equals), isDerived (equals), promoCode (contains), status (equals, in), policyId (equals, in), segmentId (equals, in), derivedRatePlanId (equals, in, is_null, is_not_null). A status filter takes one of active, expired, no-intervals, disabled; with in, several separated by a comma. It is applied before limit and offset, so a page and its total both describe the rate plans in those statuses. The in operator takes a comma-separated list of up to 100 IDs (policyId:in:1,2,3); is_null and is_not_null take no value (derivedRatePlanId:is_null). derivedRatePlanId takes 0 for the property base rate, alone or in a list (derivedRatePlanId:in:0,12), and 0 matches plans with no parent plan. derivedRatePlanId:is_null matches plans with no parent plan, which includes plans derived from the base rate; derivedRatePlanId:is_not_null matches plans whose parent is another rate plan. None of these checks isDerived, so add isDerived:equals:true to keep derived plans only. policyId, segmentId and derivedRatePlanId are filters only and cannot be sorted on.

Sort the list. Supported fields: createdAt, updatedAt, isActive, status. Multiple fields are separated by a comma (,), and each may carry a direction written as field:asc or field:desc; a field given on its own sorts ascending. status sorts in the order active, expired, no-intervals, disabled (reversed for desc). When omitted, the list is returned newest first (createdAt descending).
