from openai import OpenAI
import os
from dotenv import load_dotenv
load_dotenv()
api_key = os.getenv("OPENAI_API_KEY")
app = FastAPI()
@app.post("/generate-text/")
async def generate_text(prompt: str):
try:
response = openai.ChatCompletion.create(
model="gpt-4",
messages=[{"role": "user", "content": prompt}]
)
return {"response": response['choices'][0]['message']['content']}
except Exception as e:
raise HTTPException(status_code=500, detail=str(e))
Step 2: API Endpoint Testing
Run the FastAPI server with:
uvicorn main:app --reload
Use Swagger at http://localhost:8000/docs
for easy endpoint testing.
6. Developing the Frontend for AI Interaction

function AIChat() {
const [input, setInput] = useState("");
const [response, setResponse] = useState("");
const handleGenerate = async () => {
const res = await fetch('/generate-text/', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ prompt: input })
});
const data = await res.json();
setResponse(data.response);
};
return (
<div>
<textarea value={input} onChange={(e) => setInput(e.target.value)} />
<button onClick={handleGenerate}>Generate</button>

import redis
import hashlib
import json
redis_client = redis.Redis(host='localhost', port=6379, db=0)
def get_cached_response(prompt):
cache_key = hashlib.md5(prompt.encode()).hexdigest()
cached_data = redis_client.get(cache_key)
if cached_data:
return json.loads(cached_data)
return None
def store_response_in_cache(prompt, response):
cache_key = hashlib.md5(prompt.encode()).hexdigest()
redis_client.set(cache_key, json.dumps(response), ex=3600) # Cache for 1 hour
2. Rate Limiting
AI APIs can be costly and prone to abuse, especially if requests are unrestricted. Rate limiting ensures fair usage and protects your infrastructure from overloading.

import httpx
async def fetch_data(url):
async with httpx.AsyncClient() as client:
response = await client.get(url)
return response.json()
async def main():
tasks = [fetch_data(f'https://api.example.com/data/{i}') for i in range(10)]
results = await asyncio.gather(*tasks)
print(results)
asyncio.run(main())
Combining caching, rate limiting, load balancing, and asynchronous processing can greatly improve the performance and reliability of your AI-powered applications.
