TL;DR: Build a FastAPI REST API by installing FastAPI and Uvicorn, defining Pydantic models for porcelain gift items, and exposing CRUD endpoints with decorators. Run it with Uvicorn, then test your porcelain gift catalog endpoints via the interactive /docs page.
Step 1: Set Up Your Environment
Create a project folder and a virtual environment. Run pip install fastapi uvicorn. This gives you the web framework plus an ASGI server. For a porcelain gift API, you’ll store items like vases, teacups, and decorative plates.

Step 2: Define Your Porcelain Gift Data Model
Create main.py. Import FastAPI and Pydantic’s BaseModel. Define a PorcelainGift class with fields: id: int, name: str, category: str (e.g., “vase”, “teapot”), price: float, and in_stock: bool. Pydantic validates incoming JSON automatically, so a gift missing a price gets rejected.
Step 3: Create In-Memory Storage and CRUD Endpoints
Initialize an empty list called gifts. Add five sample porcelain items. Then define endpoints:
• GET /gifts – return all gifts.
• GET /gifts/{gift_id} – return one gift or a 404 error.
• POST /gifts – accept a PorcelainGift object and append it.
• PUT /gifts/{gift_id} – update an existing gift.
• DELETE /gifts/{gift_id} – remove a gift.
Use @app.get, @app.post, etc. FastAPI reads type hints to generate docs and validate data. Tip: For porcelain gifts, add a material: str = "porcelain" default field so you don’t repeat it.
Step 4: Run and Test the API
Run uvicorn main:app --reload. Open http://127.0.0.1:8000/docs. You’ll see Swagger UI. Try POSTing a new gift: {"id": 6, "name": "Blue Willow Teapot", "category": "teapot", "price": 89.99, "in_stock": true}. Then GET /gifts to confirm. Tip: Use the “Try it out” button to test without writing client code.
Step 5: Add Error Handling and Tips
Use HTTPException for missing gifts. For porcelain-specific logic, validate that price is positive and category is one of: vase, teacup, plate, teapot, figurine. Tip: Keep gift names unique by checking before POST. For production, replace the in-memory list with a database like SQLite via SQLAlchemy.
FAQ
Q: Can I use FastAPI for a real porcelain gift shop inventory?
A: Yes. Swap the in-memory list for a database and add authentication. The same CRUD pattern scales to thousands of porcelain products.
Q: How do I handle porcelain gift images without violating the no-image rule?
A: Store image URLs as string fields in your model (e.g., image_url: str), but never embed actual images in the API response body—just return the URL text.
