Hey @tjyang - I know restful access is a big topic for access to vault data, but as you know, currently access to the encrypted data requires a client to encrypt/decrypt the payload so that the server never has access to any decrypted data, either in flight or at rest.
You could use python to access the collection / user information in a restful manner, and also use the same python app to make bash commands with the Bitwarden CLI, and pipe the JSON back to the python application for CRUD operations.
