How this service works
Get comments on a Facebook post by post ID.
Output
Returns a list of comments on the specified Facebook post, each containing commenter details and comment text. With get_sentiment=true, each comment is enriched with a sentiment object including emotion scores (joy, trust, fear, surprise, sadness, disgust, anger, anticipation each 0-100), dominant_emotion, emotional_intensity (0-10), and polarity (positive, negative, or neutral). Multiple pages can be fetched and merged into one response.
Example use cases

Technical details
Endpoint
GEThttps://x402.apidirect.io/v1/facebook/post/comments?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically retrieve comments from a specific Facebook post by its post ID (pfbid or numeric), especially when you also want AI-powered emotion and sentiment analysis per comment. It is the right choice for social listening, brand monitoring, competitor analysis, or customer feedback extraction on Facebook. Prefer it over manual scraping or generic web access when structured, paginated comment data with optional sentiment enrichment is needed at low per-call cost.

- Private or restricted Facebook posts may return no comments
- Rate limits or Facebook access restrictions may cause partial results
- Exceeding the 20-page maximum returns a validation error
