const main = async () => {
  // get chain info
  const chain = await bcapi.getChain()

  // get block height without any optional URL params
  const block = await bcapi.getBlock(300000)

  // get block height with an optional "txstart" param, as outlined in docs here: http://dev.blockcypher.com/
  const block2 = await bcapi.getBlock(300000, {txstart: 2})

  // Let's try a post request, like making a new webhook

  }
  const createdWebHook = await bcapi.createHook(webhook)

  // Now let's list all of our webhooks
  const hooksList = await bcapi.listHooks()

  // Finally let's delete the webhook
  await bcapi.delHook(createdWebHook.id)

  return {chain, block, block2, hooksList}
