Calling 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

import Antenna from "iotex-antenna";

(async () => {
  const antenna = new Antenna("https://api.testnet.iotex.one");

  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 }
  });
})();

Using rpc-methods a standalone package:

Javascript

simport RpcMethod from "iotex-antenna/lib/rpc-method";

(async () => {
  const provider = new RpcMethod("https://api.testnet.iotex.one");

  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 }
  });
})();
