Are my Ruby and Python code samples ok?

I only checked Ruby but I think it would be better to use the standard library rather than making developers install a 3rd party http gem. Something like:

require 'net/https'
require 'uri'
require 'json'

uri = URI('https://docamatic.com/api/v1/pdf')
response = Net::HTTP.start(uri.host, uri.port, use_ssl: true) do |http|
  request = Net::HTTP::Post.new(uri)
  request.content_type = 'application/json'
  request['Authorization'] = "Bearer #{ENV['DOCAMATIC_API_KEY']}"
  request.body = JSON.generate(
    'source': 'https://news.ycombinator.com',
    'format': 'A4',
    'media': 'print'
  )

  http.request(request)
end

puts response.body

in python, i suggest f-strings

f"Bearer {os.getenv('DOCAMATIC_API_KEY')}"

I would like to look at your Python code but I didn't find any at the page you gave :-\
