// See public statuses/posts that your instance is aware of.

// The statuses will be returned in descending chronological order (newest first), with sequential IDs (bigger = newer).

// The returned Link header can be used to generate the previous and next queries when scrolling up or down a timeline.
//
// Example:
//
// ```
// <https://example.org/api/v1/timelines/public?limit=20&max_id=01FC3GSQ8A3MMJ43BPZSGEG29M>; rel="next", <https://example.org/api/v1/timelines/public?limit=20&min_id=01FC3KJW2GYXSDDRA6RWNDM46M>; rel="prev"
