# How do I poll for new and changed Hacker News content?

Use `GET /v1/hackernews/maxitem` for the current high-water `maxItemId` to catch brand-new ids, and `GET /v1/hackernews/updates` for `changedItemIds`/`changedUsernames` to catch edits to existing items and profiles. Neither returns full bodies — hydrate the ids you care about with `/items/{id}`, `/stories/{id}`, or `/users/{username}` after filtering.
