How to setup

What are the api services

How to add a service

What are needed before running

  1. Creating a Virtual Environment

    sudo apt update
sudo apt install python3.12-venv
python3 -m venv /home/ubuntu/myenv

  2. Automatically Activating the Virtual Environment

nano ~/.bashrc
source /home/ubuntu/myenv/bin/activate #add this code at the end of .bashrc file
source ~/.bashrc

  1. Git Cloning the Repository under the Branch feat/standalone-signer

Ask the administrator for permission

https://github.com/spherex-code/spherex-openapi-demo

  1. Initiating Setup Files in the Directory /spherex-openapi-demo

Copy

sudo -i 
pip install .

  1. Running Demos in the Directory /spherex-openapi-demo/tests

Substituting Your Testnet or Mainnet gRPC Path in Demo Files(ask the administrator for grpc paths)

GrpcPrivate("spherex-testnet-grpc-gateway-ex-***************.elb.ap-southeast-1.amazonaws.com", 9001,)

  1. you can find all services

**grpcurl -plaintext spherex-testnet-grpc-gateway-ex-5802c5bf04e19798.elb.ap-southeast-1.amazonaws.com:9001 list**
grpcurl -plaintext [spherex-testnet-grpc-gateway-ex-5802c5bf04e19798.elb.ap-southeast-1.amazonaws.com:9001](<http://spherex-testnet-grpc-gateway-ex-5802c5bf04e19798.elb.ap-southeast-1.amazonaws.com:9001/>) describe spherex.trade.OrderServices

  1. There are 22 services, for example

spherex.quote.QuoteService
spherex.trade.OrderService
spherex.trade.TradeService

For example, OrderServices(you can create batch order and cancel orders using this service)

https://github.com/spherex-code/spherex-protos/blob/main/protos/spherex/trade/order_rpc.proto

Quote Services(you can find market data and account position using this service)

https://github.com/spherex-code/spherex-protos/blob/main/protos/spherex/quote/quote_rpc.proto

  1. Adding a service

If you want to get open/active orders by account, you can first find the catagory(Account/Order/Quote/Trade etc.) and the service, then add the service.

# OrderService
rpc CreateOrderBatch ( .spherex.trade.CreateOrderBatchRequest ) returns ( .spherex.trade.CreateOrderBatchResponse ) {
    option (.spherex.common.rpc_method_ext_opt) = { is_write_operation:true };
  }
# /spherex-openapi-demo/spherex/grpc_private.py
def order_batch_create(self, **kwargs):
    resp = grpc_client.call_method("OrderService", "CreateOrderBatch", **kwargs)
    return resp
# /spherex-openapi-demo/spherex/order.py
class SpherexOrder:
    def __init__(self, grpc_client):
        self.grpc_client = grpc_client
		
    def create_batch_order(self, order_params_list):
		    ...
		    return create_order_batch_resp

What needs to be prepared before running

  • VPN or A Server

  • A permission for a github repo

  • An valid grpc path with a whitelisted ip

  • Account_id/L2_keys

          is_set_open_sl,
      )
      order_params_list.append(order_params)

  order_resp = self.spherexOrder.create_batch_order(order_params_list)
  print(order_resp)
