## Upload

Uploads a file to be referenced in future API calls. The file is stored under the workspace of the authenticating API key. Maximum file size: 100 MB; empty files are rejected. The file type is determined from the file contents — not the filename or the declared content type — and must be a PDF, a PNG/JPEG/GIF/WebP image, a DOCX/XLSX/PPTX document, an MP3/WAV/FLAC/OGG audio file, or UTF-8 text. Text is reported by its structure as `application/json`, `application/x-ndjson`, `text/csv`, `text/markdown`, or `text/plain`.

### Example Usage

```go theme={null}
package main

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

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

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

    example, fileErr := os.Open("example.file")
    if fileErr != nil {
        panic(fileErr)
    }

    res, err := s.Files.Upload(ctx, operations.UploadFileRequestBody{
        File: operations.UploadFileFile{
            FileName: "example.file",
            Content: example,
        },
    }, nil, components.FileProviderOpenai.ToPointer())
    if err != nil {
        log.Fatal(err)
    }
    if res != nil {
        switch res.Type {
            case components.FileResponseTypeAnthropic:
                // res.AnthropicFile is populated
            case components.FileResponseTypeOpenai:
                // res.OpenAIFile is populated
            case components.FileResponseTypeOpenrouter:
                // res.OpenRouterFile is populated
            default:
                // Unknown type - use res.GetUnknownRaw() for raw JSON
        }

    }
}
