### Example Usage

```typescript theme={null}
import { OpenRouter } from "@openrouter/sdk";

const openRouter = new OpenRouter({
  httpReferer: "<value>",
  appTitle: "<value>",
  appCategories: "<value>",

});

async function run() {
  const result = await openRouter.files.list();

  for await (const page of result) {
    console.log(page);
  }
}

run();
```

### Standalone function

The standalone function version of this method:

```typescript theme={null}
import { OpenRouterCore } from "@openrouter/sdk/core.js";
import { filesList } from "@openrouter/sdk/funcs/filesList.js";

// Use `OpenRouterCore` for best tree-shaking performance.
// You can create one instance of it to use across an application.
const openRouter = new OpenRouterCore({
  httpReferer: "<value>",
  appTitle: "<value>",
  appCategories: "<value>",
  apiKey: process.env["OPENROUTER_API_KEY"] ?? "",

## 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

```typescript theme={null}
import { OpenRouter } from "@openrouter/sdk";
import { openAsBlob } from "node:fs";

const openRouter = new OpenRouter({
  httpReferer: "<value>",
  appTitle: "<value>",
  appCategories: "<value>",
  apiKey: process.env["OPENROUTER_API_KEY"] ?? "",
});

async function run() {
  const result = await openRouter.files.upload({
    provider: "openai",
    requestBody: {
      file: await openAsBlob("example.file"),
    },
  });

  console.log(result);
}

run();
```

### Standalone function

The standalone function version of this method:

```typescript theme={null}
import { OpenRouterCore } from "@openrouter/sdk/core.js";
import { filesUpload } from "@openrouter/sdk/funcs/filesUpload.js";
import { openAsBlob } from "node:fs";

// Use `OpenRouterCore` for best tree-shaking performance.
// You can create one instance of it to use across an application.
const openRouter = new OpenRouterCore({
  httpReferer: "<value>",
  appTitle: "<value>",

async function run() {
  const res = await filesUpload(openRouter, {
