import requests
from bs4 import BeautifulSoup


data = {
    "queryString": "machine learning",
    "page": 1,
    "pageSize": 10,
    "sort": "relevance",
    "authors": [],
    "coAuthors": [],
    "venues": [],
    "yearFilter": 'null',
    "requireViewablePdf": 'false',
    "publicationTypes": [],
    "externalContentTypes": []
}
r = requests.post(
    'https://www.semanticscholar.org/api/1/search', json=data).json()

print(r)
