Apps with no excess growth are omitted from `trending` results. ## Example Usage ```go theme={null} import ( "github.com/OpenRouterTeam/go-sdk/models/operations" ) value := operations.GetAppRankingsSortPopular // Open enum: custom values can be created with a direct type cast custom := operations.GetAppRankingsSort("custom_value") ``` ## Values | Name | Value | | ---------------------------- | -------- | | `GetAppRankingsSortPopular` | popular | | `GetAppRankingsSortTrending` | trending |
