associate_tag = 'YOUR_ASSOCIATE_TAG'

# Construct the API request URL
url = f"https://webservices.amazon.com/paapi5/searchitems?keyword=laptop&associateTag={associate_tag}"

headers = {
    "Content-Type": "application/json",
    "X-Amz-Access-Token": access_key,
}

response = requests.get(url, headers=headers)
data = response.json()

# Print the data
print(json.dumps(data, indent=4))
