Nice! I hope that this gets sufficient interest for you to leave it up.

But the cursor seems to be zero based on each story collection, so I can't figure out how to read just stories up to a given story:

  {
    newStories(after: "3") {
      edges {
        node {
          url
          title
        }
        cursor
      }
    }
  }

How would I query stories since a given story or datetime?

Thanks! The GraphQL API is just a wrapper of HackerNews REST API (doc: https://github.com/HackerNews/API)

The REST endpoints do not provide a way to query the items with variable parameters. So, I could not support it either on GraphQL side.
