Facebook Comment Replies Scraper API

The Facebook Comment Replies endpoint is one API call: send a feedback ID and a expansion token with your HProxy key and get back a clean, structured JSON object. Pull the full nested reply thread under any Facebook comment, so you can rebuild the conversation rather than just the top level. HProxy runs the proxies, sessions, anti-bot handling and parsing server-side, so there is no headless browser to babysit and no parser to keep fixing when Facebook changes its markup. You only ever touch the JSON. Longer result sets come back page by page with a cursor, so you can walk the whole set without holding it in memory.

How it works

Scraping Facebook comment replies, in three steps.

You write one line. Proxies, anti-bot walls, rendering and parsing happen on our side.

Answered before you ask.

The reference

Send one authenticated HTTPS request to the Facebook Comment Replies endpoint with a feedback ID and a expansion token and your HProxy API key. Pull the full nested reply thread under any Facebook comment, so you can rebuild the conversation rather than just the top level. No proxies, no headless browser and no parsing on your side. The response is ready-to-use JSON.

This endpoint is 0.15¢ per successful call, which is $1.49 per 1,000. It bills from your HProxy balance with no subscription and no monthly minimum. Errors are retried and never charged; a lookup whose target does not exist counts as a call.

No. Every call runs on HProxy's own residential network behind the scenes, so requests look like real users. The proxy layer is already included in the per-call price.

A structured JSON object with the full comment replies data Facebook exposes publicly. See the fields listed above. The schema is consistent across calls, so you integrate once and rely on it.

Yes. The response carries a cursor; pass it back on the next call to continue from where you stopped. Each page is one billable call, so you only pay for the depth you actually pull.

The API only accesses publicly available Facebook data, the same pages anyone can open in a browser. You are responsible for using the data in line with applicable laws and Facebook's terms for your use case.

Docs and AI

Connect your scraper to an AI, any time.

The whole Scraper API is published as markdown, so an assistant reads every endpoint, every parameter and a real response without a key and writes your integration. And because a scrape is one GET that answers in JSON, an agent can run the scraper itself, on its own schedule, with your key.

An agent can call it

One GET with your key returns structured JSON, so an agent scrapes on its own schedule. No browser to drive, no parser to keep alive between runs.

More on the Facebook Comment Replies API

What the Facebook Comment Replies endpoint returns

Pull the full nested reply thread under any Facebook comment, so you can rebuild the conversation rather than just the top level. The JSON object carries replies[], parentId, depth and cursor. Nothing is summarised away on our side, so what you read in the response is what the Facebook comment replies page itself holds.

What you send to the Facebook Comment Replies API

The call takes a feedback ID and a expansion token. Required: feedback_id and expansion_token. Optional: cursor. Your key travels in the X-API-Key header, the response is JSON, and the call is billed at 0.15¢, $1.49 per 1,000.

Comments on other platforms

The same comments data is available on 4 other platforms: TikTok Comment Replies, YouTube Comment Replies, Instagram Post Comments and Reddit Post Comments. They share this endpoint's JSON shape, its per-call billing and your one API key, so moving from Facebook to another network is a change of URL rather than a second integration.

Is scraping Facebook comment replies allowed?

The endpoint reads publicly available Facebook data, the same pages anyone can open in a browser without logging in. It does not touch private accounts or anything behind a password. How you then use the data is yours to keep lawful, under the rules that apply to you and to Facebook.

Ready when you are.

Your dashboard is ten seconds away. No sales call, no subscription, no minimum.
