For the gRPC interface, when the following code is executed:
grpc_client = GrpcApiClient(your_app_key, your_app_secret, 'us')
QuotesApiClient quotesApiClient = QuotesApiClient.builder()
A gRPC connection will be initialized, and subsequent interface requests will use this gRPC connection for data request and reception. Every time a connection is established, we consider it a market session, and each App Key can only establish a maximum of 10 gRPC connections.
Some interfaces support gRPC and HTTP interfaces, which are convenient for users to obtain data. However, the token acquisition, subscription, and unsubscribe interfaces related to MQTT persistent connection only support gRPC calls.
