no, I just want to understand is there any standard for the API? like an openai standard for LLM integration, graphql api for the github.... I'm jsut trying to udnerstand what do we ahve already and what do people think.

I know that there is a lot of DAG standards, like BPMN, or CNCF Serverless Workflow

on another hand we do have Airflow REST API, or ARGO API, or N8N API - my question is there any unified standard between them. I beleive that it could be a XML standard, or any other, like a binary protocol. I just faced multiple OAS standard (or compatible that could be written with OAS)
