Create a chain for querying an API from a OpenAPI spec.

  • spec – OpenAPISpec or url/file/text string corresponding to one.

  • llm – language model, should be an OpenAI function-calling model, e.g. ChatOpenAI(model=”gpt-3.5-turbo-0613”).

  • prompt – Main prompt template to use.

  • request_chain – Chain for taking the functions output and executing the request.
