Discogs API limitation in retrieving more than 7 releases per label in a specific year

Question

I'm trying to get the list of labels present in 1991 using Discogs API but if I set the number of results above 7 (for example 9, 10 or 20..) I am always given a maximum of 7 results

My code is this

import requests
from urllib.parse import quote

user_token = '*********kz*******'

label_name = input("Inserisci il nome dell'etichetta: ")
num_label_results = int(input("How many results do you want to see for the label? "))
response = requests.get(f'https://api.discogs.com/database/search?type=label&q={quote(label_name)}&token={user_token}&per_page={num_label_results}')
label_results = response.json()['results']

print("Results for the label:")
for i, label_result in enumerate(label_results):
    print(f"{i+1}. {label_result['title']}")

label_choice = int(input("Choose a label by entering the corresponding number: ")) - 1
selected_label = label_results[label_choice]

year = input("Enter the year for the releases of the selected label: ")

# Ask how many results they want to see for the label's releases in the specified year
num_year_results = int(input(f"How many results do you want to see for label releases '{selected_label['title']}' in the year {year}? "))

response = requests.get(f'https://api.discogs.com/database/search?type=release&label={quote(selected_label["title"])}&year={year}&token={user_token}&per_page={num_year_results}')
year_results = response.json()['results']

print("Debug information:")
print("Search URL:", response.url)
print("API response:", response.json())

print("Results by label and year:")
for i, year_result in enumerate(year_results):
    # Get release details
    response = requests.get(f'https://api.discogs.com/releases/{year_result["id"]}?token={user_token}')
    release_details = response.json()

    # Get the year of release and record label, if available
    release_year = release_details.get('year', 'N/A')
    labels = ', '.join(label['name'] for label in release_details.get('labels', []))

    print(f"{i+1}. {year_result['title']} ({release_year}) - Label: {labels}")

Basically the important part is where the user can choose the number of results to display. I would also like to understand if the empty spaces in the label are correctly managed
