US Patent 11429400 User interface metadata from an application program interface

A method includes receiving, from a client device, a request for graphical user metadata (GUM) associated with an application program interface (API), wherein the request is directed to a well-known GUM endpoint of the API. The method further includes in response to determining, by a processing device, that the well-known GUM endpoint corresponds to the GUM, generating a GUM response corresponding to the GUM and providing a GUM response corresponding to the GUM to the client device. The method further includes in response to determining, by the processing device, that the well-known endpoint does not correspond to the GUM, providing an error message to the client device.
