Congratulations you have successfully Tested OpenAI's Embeddings API endpoint with Postman using the secret key that you created in your OpenAI Account.

Let's Summarize

Embeddings are vector representations of a given input that can be easily consumed by machine learning models and algorithms. OpenAI provides an API Endpoint to get these embeddings for an input. In this episode, we installed  POSTMAN to test this endpoint without actually creating any application. We created a Secret key in our OpenAI Account & used the same to Authenticate & consume the OpenAI endpoint. That's all for this episode, will meet you guys in Episode 3.
