How this service works
Pay-per-request access to social media data from TikTok, Instagram, Facebook, Reddit, and LinkedIn. No auth, no subscriptions.
Output
Returns a list of reply objects for the specified Facebook comment, each containing reply content, author details, timestamps, and reaction counts, plus a pagination cursor for fetching additional pages of replies.
Example use cases

Competitive research on viral posts
“Fetch the replies to that comment on our competitor's viral Facebook post — feedback_id is COMP_POST_112 and expansion_token is TOK_EXPAND_99 — I want to see what people are saying in the thread.”

Technical details
Endpoint
POSThttps://stablesocial.dev/api/sc/facebook/post/comment/repliesWhen to prefer
Choose this endpoint when you need to retrieve replies nested under a specific Facebook comment and already have the feedback_id and expansion_token from a prior call to the /facebook/post/comments endpoint. It's ideal for pay-per-request use without requiring OAuth or subscriptions, making it suitable for one-off or low-volume data extraction tasks on public Facebook content.
Side effects
- Invalid or missing feedback_id returns an error — note that feedback_id is NOT the comment id
- Invalid or expired expansion_token causes request failure
- Invalid cursor value breaks pagination and may return no results
- Rate limits or payment failures result in 402 responses
- Non-public or restricted Facebook comments may return empty or error responses
