Update:
A public demo instance is available on HuggingFace Space - https://atrifat-hate-speech-detector-api-demo.hf.space. There is no guarantee for the uptime, but feel free to test this API server.
There is no Graphical UI (yet), so we can test it using tools like Postman, Reqbin, or Curl:
curl https://atrifat-hate-speech-detector-api-demo.hf.space/predict --header "Content-Type: application/json" --request POST --data '{"api_key":"", "q":"good morning"}'
Reqbin test tool: https://reqbin.com
