Comments / Replies
Returns the comment tree for a post URL: author name and avatar, comment text, reaction count, reply count and timestamps, with cursors for long threads. Built for social listening, moderation and customer-feedback mining.

Parameters
The public Facebook post URL to resolve.
Maximum records to return, capped at this service's page size (see Limits below). Omit it to receive the whole page. It shapes the response, not the price — a call costs the same either way.
Pagination cursor returned by a previous response.
Bypass cached data and force a live fetch for this one call. Use it for daily monitoring or any figure you are tracking over time. Accepts `true`, `1`, `false` or `0`; anything else returns 400 `invalid_fresh`. Defaults to false and costs exactly the same as a cached call.
One of: true, 1, false, 0
Example request
Live call. Successful calls are charged; failed and empty results are not.

- Maximum per call: 20 comments.
- Minimum per call: 1 comment — a target with less data returns fewer comments, and an empty result is still a successful call.
- Pass limit to receive fewer than 20 comments. It shapes the response, not the price.
- Larger jobs are paginated with a cursor; there is no cap on how many pages you fetch.
What this costs in practice
