Start with our example code on GitHub.

Walkthrough

1. npm install oraqle-contracts ethers

2. Use the following JavaScript code to request results from either oraqle.

const ethers = require("ethers");
const addresses = {
  kovan: "0x0792724900B551d200D954a5Ed709d9514d73A9F",
  mainnet: "0x3E961f9A77146F6230709D767d60025f1Ed3Bfef",
};
const positions = ["U.S. Senate Class II", "U.S. Senate Class III"];
const abi = require("oraqle-contracts/artifacts/contracts/associated-press/Jan2021SenateRunoffs.sol/Jan2021SenateRunoffs.json")
  .abi;
  
const checker = async (network: "kovan" | "mainnet") => {
  let provider = ethers.getDefaultProvider(network);
  const contractAddress = addresses[network];

  const contract = new ethers.Contract(contractAddress, abi, provider);

  const lastNames = await Promise.all(
    positions.map((position) => contract.winners(position))
  );

  return lastNames;
};
