OpenAI Fundamentals

**Definition**: Your API key or token was invalid, expired, or revoked

**Possible solution**: Check that your API key or token is correct and has not been revoked or expired

**Definition**: Your request is missing required parameters, or some of the parameters are invalid

**Possible solution**: Double check the variables and parameters you are passing as input and ensure they are valid and in the correct format

**Definition**: You have exceeded the number of requests you can send within a given time

**Possible solution**: decrease the number of requests you are sending to the API within a given time
