# GET with query parameter
curl "https://nipun-api-testing.hf.space/greet?name=Alice"

# POST with JSON body
curl -X POST https://nipun-api-testing.hf.space/items \
  -H "Content-Type: application/json" \
  -d '{"name": "Book", "price": 15.99, "quantity": 10}'

# PUT to update
curl -X PUT https://nipun-api-testing.hf.space/items/1 \
  -H "Content-Type: application/json" \
  -d '{"name": "Updated Apple", "price": 2.00, "quantity": 50}'

# DELETE
curl -X DELETE https://nipun-api-testing.hf.space/items/1

# Get different formats
curl https://nipun-api-testing.hf.space/format/xml
curl https://nipun-api-testing.hf.space/format/html

# Test status codes
curl -i https://nipun-api-testing.hf.space/status/404
curl -i https://nipun-api-testing.hf.space/status/201
```

### Using Python requests

```python
import requests

BASE = "https://nipun-api-testing.hf.space"

# GET request
response = requests.get(f"{BASE}/hello")
print(response.json())

# GET with parameters
response = requests.get(f"{BASE}/greet", params={"name": "Alice"})
print(response.json())

# POST with JSON
data = {"name": "Laptop", "price": 999.99, "quantity": 5}
response = requests.post(f"{BASE}/items", json=data)
print(response.status_code)  # 201
print(response.json())

# Check headers
response = requests.get(f"{BASE}/headers")
print(response.json())
```
