Overview

Facebook Post Comments fetches one page of public comments for a Facebook post or Reel by URL or feedback ID, preserving comment authors, text, timestamps, reaction and reply counts, comment feedback IDs, reply expansion tokens, and next-page cursor when returned. Use it to mine audience reactions after inspecting a post.

Use cases

  • Review public comments on a Facebook post or Reel for audience reaction patterns.
  • Capture comment text, author summaries, timestamps, reactions, replies, feedback IDs, and expansion tokens.
  • Page through comment results with a returned cursor or start from a feedback ID captured by Facebook Post Details.

Input tips

  • Provide either a full HTTPS Facebook post or Reel URL, or a feedback ID from Facebook Post Details.
  • Prefer the feedback ID when available because it can fetch comments faster.
  • Use the cursor from a previous result to fetch another comments page.
  • Omit cursor to fetch the first comments page.

Expected output

The AI Tool returns availability and pagination status, lookup kind, requested identifier, canonical source URL or requested feedback ID, requested cursor, next cursor, normalized comments, comment count, reply-expansion count, warnings, normalization notes, additional recovered fields, and cost metadata. Comments can include IDs, text, timestamps, feedback IDs, reply expansion tokens, author summaries, reaction counters, reply and reaction engagement counts, and per-comment recovered fields when returned.

Caveats

  • Each run returns one comments page, not the full comment history.
  • An empty result can mean no public comments, disabled comments, a stale feedback ID, or an invalid cursor.
  • Comment visibility, counts, authors, and cursors can change after the run.
  • Expansion tokens are preserved for follow-up, but they may not expose every reply.
