# FastAPI / Async Python Example
from fastapi import FastAPI, UploadFile, File
from smallpict import AsyncSmallPictClient, ImageFormat

app = FastAPI()
client = AsyncSmallPictClient(api_key="sp_live_key_xxxxx")

@app.post("/api/upload")
async def upload_image(file: UploadFile = File(...)):
    image_bytes = await file.read()
    result = await client.optimize(
        image_bytes,
        format=ImageFormat.AVIF,
        quality=80,
        max_width=1400
    )
    return {
        "cdn_url": result.cdn_url,
        "savings": f"{result.savings_percentage}%",
        "original_size": result.original_size,
        "optimized_size": result.new_size
