How to get Facebook comments

TL;DR

To get Facebook comments, sign up for a free Captapi key, then send one GET request to /v1/facebook/comments with your input. You get clean JSON back in seconds for ~30 credits (0.6/result) per call — no OAuth, scraping or platform SDKs. Pull Facebook comments with author, text, likes, and timestamps.

How to get Facebook comments (step by step)

1
Get a free API key
Create a free Captapi account (100 credits, no card) and generate an API key from the dashboard.
2
Call the Facebook Comments API
Send an authenticated GET request to /v1/facebook/comments with your input. No OAuth, no scraping setup.
3
Read the JSON response
Parse the clean JSON response. Pass cache=true for a free 24h cache hit; default is always fresh.

Code example

curl "https://api.captapi.com/v1/facebook/comments?url=https%3A%2F%2Fwww.facebook.com%2FNASA%2Fposts%2Fpfbid02skzNsrLf5atYZfzvzHAK9gHwDnZC5u4pDZMLQ1u3iJmfoA8tNsGpT7Uj6WPs6K3Rl" \
  -H "Authorization: Bearer capt_live_..."
# or: -H "x-api-key: capt_live_..."

Billing metadata (credits charged, cache hit/miss) is returned in the X-Captapi-Credits and X-Captapi-Cache response headers.

Request parameters

Name	Type	Required	Description

cache	boolean	No	Set true to serve from the 24h response cache. Default false — always fetch fresh data.

Frequently asked questions

What does the Facebook Comments API do?

The Facebook Comments API lets you pull comments with author, text, likes, and replies from a public Facebook video using one GET request to /v1/facebook/comments. It returns clean JSON — no OAuth or infrastructure setup required.

How many credits does the Facebook Comments API cost?

At the default limit this endpoint costs 30 credits (0.6 per result). Billing scales with how many results you request. Pass cache=true to serve from the 24h shared cache (0 credits on hit); default is always fresh. Failed or empty results are never charged.

Do I need a Facebook API key or OAuth?

No. A single Captapi key works across every platform Captapi supports — YouTube, TikTok, Instagram, Facebook, Twitter/X, Reddit, Threads, Bluesky, Pinterest, LinkedIn, Rumble, Spotify, Kwai, and more. We handle proxies, rate limits, retries, and authentication for you.

Is the Facebook Comments API suitable for production use?

Yes. It is a stable REST endpoint with predictable JSON and automatic retries. Pass cache=true to serve from the 24h shared cache (0 credits on hit); default is always fresh. Use it for analytics, monitoring, and content automation.
