API

The framework for interacting with a remote API.

All methods that interact with the API should return raw, unprocessed responses.

Classes:

RemoteAPI(authoriser, wrangler[, cache])

Collection of endpoints for a remote API.

class musify.libraries.remote.core.api.RemoteAPI(authoriser, wrangler, cache=None)

Bases: ABC

Collection of endpoints for a remote API. See RequestHandler and APIAuthoriser for more info on which params to pass to authorise and execute requests.

Parameters:

authoriser (APIAuthoriser) – The authoriser to use when authorising requests to the API.
cache (ResponseCache | None (default: None)) – When given, attempt to use this cache for certain request types before calling the API. Repository and cachable request types can be set up by child classes.

If JSON response(s) given, this updates each response given by merging with the new response.

If RemoteResponse values are given, this function will call refresh on them.

Parameters:

Returns:

list[dict[str, Any]] – API JSON responses for each item.

Raises:

RemoteObjectTypeError – Raised when the function cannot determine the item type of the input values. Or when it does not recognise the type of the input values parameter.
