Pagination

This endpoint pages by offset:

Make an initial request with start=0
If hasMore is true, add the number of comments you received to start
Continue until hasMore is false or a page comes back empty

A page can be much shorter than count and still not be the last one — the first page of a busy thread often returns a handful of comments while hundreds remain. Trust hasMore, not the number of items returned.

async function fetchAllComments(postUrlOrUrn) {
  const allComments = [];
  let start = 0;
  let hasMore = true;

  while (hasMore) {
    const params = new URLSearchParams({
      postUrlOrUrn,
      count: '100',
      start: String(start),
    });

    const response = await fetch(
      `https://api.fetchin.io/api/v1/post/comments?${params}`,
      { headers: { 'X-API-Key': 'your-api-key-here' } }
    );

    const data = await response.json();
    if (data.comments.length === 0) break;

    allComments.push(...data.comments);
    start += data.comments.length;
    hasMore = data.hasMore;
  }

  return allComments;
}

Notes

This endpoint consumes 1 credit from your monthly quota per API call, regardless of the count parameter value.

Comments are returned in relevance order by default. Each comment includes its replies (subcomments) nested within.

Use the paginationToken to efficiently paginate through large comment sections without re-fetching already retrieved comments.
