Deprecated: Prefer POST /operations/searchInfos when you need a stable sort or pagination without unmarshalling full intents. Returns operations' intents matching the filter. If Statuses is omitted or empty, only operations that are not in a final state (Succeeded or Failed) are included. There is no limit field on the filter; this endpoint may return unbounded payloads. Matches are returned in arbitrary order (not ordered by creation time). The 200 response body is a ListOperationsResult: Intents is a JSON array of stored intent objects (standard application/json encoding of each intent struct). Each element matches one variant of IntentItem when the operation type is still startable over HTTP; use the object's OperationType field to select the variant. Older operation types that can no longer be started (for example transfer, add ERC20 asset) may still appear in responses but are omitted from the IntentItem union. This is not a base64 blob, json.RawMessage, or double-encoded JSON string layer. Returned intents include common metadata when present: OperationType, optional OperationID and InitiatorID, and server fields such as Timestamp and InitiatorName (see each variant under IntentItem).
