Pagination

To fetch all comments from a post with many comments, use pagination:

Make an initial request without paginationToken
If hasMore is true, use the returned paginationToken in your next request
Continue until hasMore is false

async function fetchAllComments(postUrn) {
  const allComments = [];
  let paginationToken = null;
  let hasMore = true;

  while (hasMore) {
    const params = new URLSearchParams({ postUrn, count: '100' });
    if (paginationToken) {
      params.set('paginationToken', paginationToken);
    }

    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();
    allComments.push(...data.comments);
    paginationToken = data.paginationToken;
    hasMore = data.hasMore;
  }

  return allComments;
}

Notes

This endpoint counts as 1 request toward 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.
