Call any RPC method

The rpc-method package allows you to make direct gRPC calls to the IoTeX blockchain. The complete gRPC API can be found in the iotex-proto GitHub repository, and all calls can be made both using the umbrella antenna.iotex object or using the rpc-method as a standalone package.
Using antenna.iotx
Javascript
Golang
import Antenna from "iotex-antenna";
​
(async () => {
  const antenna = new Antenna("http://api.testnet.iotex.one:80");
​
  const account = await antenna.iotx.getAccount({
    address: "io1cl6rl2ev5dfa988qmgzg2x4hfazmp9vn2g66ng"
  });
  const chainMeta = await antenna.iotx.getChainMeta();
  const actions = await antenna.iotx.getActions({
    byIndex: { start: 1, count: 5 }
  });
  const blocks = await antenna.iotx.getBlockMetas({
    byIndex: { start: 1, count: 5 }
  });
})();
​
package main
​
import (
	"log"
​
	"github.com/iotexproject/iotex-core/protogen/iotexapi"
​
	"github.com/iotexproject/iotex-antenna-go/antenna"
)
​
func main() {
	wallet, err := antenna.NewAntenna("api.testnet.iotex.one:80")
	if err != nil {
		log.Fatalf("create antenna error: %v", err)
	}
​
	account, err := wallet.Iotx.GetAccount(&iotexapi.GetAccountRequest{Address: "io1cl6rl2ev5dfa988qmgzg2x4hfazmp9vn2g66ng"})
	chainMeta, err := wallet.Iotx.GetChainMeta(&iotexapi.GetChainMetaRequest{})
	actions, err := wallet.Iotx.GetActions(&iotexapi.GetActionsRequest{
		Lookup: &iotexapi.GetActionsRequest_ByIndex{
			ByIndex: &iotexapi.GetActionsByIndexRequest{
				Start: 1,
				Count: 5,
			},
		},
	})
	blocks, err := wallet.Iotx.GetBlockMetas(&iotexapi.GetBlockMetasRequest{
		Lookup: &iotexapi.GetBlockMetasRequest_ByIndex{
			ByIndex: &iotexapi.GetBlockMetasByIndexRequest{
				Start: 1,
				Count: 5,
			},
		},
	})
}
​
Using rpc-methods a standalone package:
Javascript
Golang
import RpcMethod from "iotex-antenna/lib/rpc-method";
​
(async () => {
  const provider = new RpcMethod("http://api.testnet.iotex.one:80");
​
  const account = await provider.getAccount({
    address: "io1cl6rl2ev5dfa988qmgzg2x4hfazmp9vn2g66ng"
  });
  const chainMeta = await provider.getChainMeta();
  const actions = await provider.getActions({
    byIndex: { start: 1, count: 5 }
  });
  const blocks = await provider.getBlockMetas({
    byIndex: { start: 1, count: 5 }
  });
})();
​
package main
​
import (
	"log"
​
	"github.com/iotexproject/iotex-antenna-go/rpcmethod"
​
	"github.com/iotexproject/iotex-core/protogen/iotexapi"
)
​
func main() {
	provider, err := rpcmethod.NewRPCMethod("api.testnet.iotex.one:80")
	if err != nil {
		log.Fatalf("create antenna error: %v", err)
	}
​
	account, err := provider.GetAccount(&iotexapi.GetAccountRequest{Address: "io1cl6rl2ev5dfa988qmgzg2x4hfazmp9vn2g66ng"})
	chainMeta, err := provider.GetChainMeta(&iotexapi.GetChainMetaRequest{})
	actions, err := provider.GetActions(&iotexapi.GetActionsRequest{
		Lookup: &iotexapi.GetActionsRequest_ByIndex{
			ByIndex: &iotexapi.GetActionsByIndexRequest{
				Start: 1,
				Count: 5,
			},
		},
	})
	blocks, err := provider.GetBlockMetas(&iotexapi.GetBlockMetasRequest{
		Lookup: &iotexapi.GetBlockMetasRequest_ByIndex{
			ByIndex: &iotexapi.GetBlockMetasByIndexRequest{
				Start: 1,
				Count: 5,
			},
		},
	})
}
