I didn’t mean they’re exactly equivalent, but they share the fundamental concern that client code relies on the data structures being passed. In the case of an API, it’s the request parameters and response body — though in a GraphQL API it would look even closer to a DB query. So, many of these rules still apply: You should only grow an existing API, not shrink it. You shouldn’t rename things in an API. You shouldn’t use the same name with different meanings except in different namespaces/endpoints. Etc.
