# FileListResponse

A page of files, in the negotiated shape.

## Supported Types

### AnthropicFileList

```go theme={null}
fileListResponse := components.CreateFileListResponseAnthropic(components.AnthropicFileList{/* values here */})
```

### OpenAIFileList

```go theme={null}
fileListResponse := components.CreateFileListResponseOpenai(components.OpenAIFileList{/* values here */})
```

### OpenRouterFileList

```go theme={null}
fileListResponse := components.CreateFileListResponseOpenrouter(components.OpenRouterFileList{/* values here */})
```

## Union Discrimination

Use the `Type` field to determine which variant is active, then access the corresponding field:

```go theme={null}
switch fileListResponse.Type {
	case components.FileListResponseTypeAnthropic:
		// fileListResponse.AnthropicFileList is populated
	case components.FileListResponseTypeOpenai:
		// fileListResponse.OpenAIFileList is populated
	case components.FileListResponseTypeOpenrouter:
		// fileListResponse.OpenRouterFileList is populated
	default:
		// Unknown type - use fileListResponse.GetUnknownRaw() for raw JSON
}
```
