## 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`.

from openrouter import OpenRouter
import os


with OpenRouter(

    api_key=os.getenv("OPENROUTER_API_KEY", ""),
) as open_router:

    res = open_router.files.upload(file={
        "file_name": "example.file",
