In order to test the API we need to get an API Key:
OpenAI provides a free tier for the GPT-3 API that allows developers to experiment with the API and build small-scale applications without incurring any costs.
The free tier provides access to a limited number of API requests per month, after which you will need to upgrade to a paid plan to continue using the API.
It's important to note that the availability and terms of these resources may change over time, so it's best to check with OpenAI directly for the most up-to-date information on their programs and offerings.
Supported languages: it provides several SDKs and libraries to use the API in different programming languages, including Python, Node.js, Java, Ruby, C#
