I recently profiled the Wolfram Alpha LLM API. There are additional APIs to be profiled, but I wanted to get this one in the system so we could use as part of other work.
One thing I tested with this one was the ability for ChatGPT to generate an OpenAPI if I pasted specific content from the Wolfram Alpha LLM API page. It did a really good job producing the OpenAPI in the repo and is something I will continue to use and automate around.
You can visit the APIs.yml and OpenAPI over at the GitHub repository for Wolfram Alpha LLM API, and we will keep adding other APIs and common properties for Wolfram Alpha LLM API as time allows.
