body: <p>I want to automate sending pings to rpc.pingomatic.com but I can't find anywhere which documents the fields to send in the RPC document.</p>
  
  <p>I'm not worried about a fancy RPC generator. I'm happy just to #{...} the link into a static string. I just need to know what to insert it into.</p>
