I open sourced this tool that takes OpenAPI spec and let you control API using natural language https://github.com/mquan/api2ai

Let me know if you have any questions or feature request

How is this different from what LangChain already offers with their OpenAPI chain?

afaik, the langchain solution loads entire openAPI spec which consumes a lot of token and won't work for many large API. For efficient token usage, api2ai divides the task into two steps: api planning and params parsing. First step takes a summarization of all the endpoints. Once the endpoint is known, we parse params using the schema of the selected endpoint.
