## Overview

Containers endpoints

### Available Operations

* [ListContainerFiles](#listcontainerfiles) - List container files
* [GetContainerFile](#getcontainerfile) - Retrieve a container file
* [DownloadContainerFileContent](#downloadcontainerfilecontent) - Download container file content

## ListContainerFiles

Lists the files under a sandbox session prefix, in lexicographic path order. A restarted session is a separate container with its own session id. Paginate with `limit` and `after` (pass the previous page’s `last_id`); `has_more: true` always means the next page is fetchable that way.

### Example Usage

```go theme={null}
package main

import(
	"context"
	"os"
	openrouter "github.com/OpenRouterTeam/go-sdk"
	"log"
)

func main() {
    ctx := context.Background()

    s := openrouter.New(
        openrouter.WithSecurity(os.Getenv("OPENROUTER_API_KEY")),
    )

    res, err := s.Containers.ListContainerFiles(ctx, "sess-abc123", openrouter.Pointer[int64](100), nil)
    if err != nil {
        log.Fatal(err)
    }
    if res != nil {
        // handle response
    }
}
```
