# FastAPI Example - User Authentication Endpoint
from fastapi import FastAPI, HTTPException, Depends
from fastapi.security import OAuth2PasswordBearer
from pydantic import BaseModel
import jwt

app = FastAPI(title="AttiqLab API", version="1.0.0")

class User(BaseModel):
    username: str
    email: str
    full_name: str

@app.post("/api/v1/auth/login")
async def login(credentials: LoginCredentials):
    """Authenticate user and return JWT token"""
    user = await authenticate_user(credentials)
    if not user:
        raise HTTPException(401, "Invalid credentials")
    
    token = create_jwt_token(user)
    return {"access_token": token, "token_type": "bearer"}
