I learned that OpenAI has integrated vector store now so I do not need an external vector database. So my question is if it is all possible with just API requests using curl

Can I create a vector store with curl .

and then upload 2 PDFs to vector with just a curl command.

And then I can ask quesiton also just with a curl.

i want to test it out only using API requests, and would be immensely amazing, if its possible ?
