API is adding an extra parameter that is conficting with the API routes

could you help me out? am getting this error 'POST http://127.0.0.1:8000/blog/api/blog 405 (Method Not Allowed)' i know the route is the problem, but how do I fix it? its supposed to be 'http://127.0.0.1:8000/api/blog' why is it adding the extra blog after 8000?
