## Pricing

from $2.00 / 1,000 results

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## Facebook Comment Scraper

> **Thirdwatch portfolio:** 8,800+ users across 140+ public Actors, 2M+ records delivered, >95% run success. [Explore all Thirdwatch Actors](https://apify.com/thirdwatch).

> Extract comments from public Facebook post URLs — commenter names, text, and reactions where publicly visible.

### What you get

Extract comments from public Facebook post URLs — commenter names, text, and reactions where publicly visible.

### Why use this Facebook Comment scraper

- **Mobile-web surface** — uses `m.facebook.com` public post rendering, no login.
- **Comment fields** — author, text, and reaction hints per row.
- **Honest errors** — login-walled or comment-free posts produce explicit error rows.

### Scrape Facebook Comment data in minutes

```json
{
  "urls": [
    "https://www.facebook.com/nasa/videos/"
  ],
  "maxResults": 10
}
```

### Input parameters

| Parameter | Required | Description |
|---|---:|---|
| `urls` | Yes | Facebook post URLs. |
| `maxResults` | No | Max comments per post. Default: `10`. |

### Output fields

- `postUrl`
- `error`

### Common use cases

- Sample discussion on public posts
- Monitor engagement on brand/page posts
- Research public sentiment on announcements

### Compared to alternatives

- **vs other Facebook Comment scrapers on the Store** — pay-per-result billing means empty or failed searches cost nothing; you are not charged for a run that returns zero rows.
- **vs building your own** — no proxy management, markup-change maintenance, or infrastructure to run; paste inputs and consume the dataset.

### Limitations

- Many posts render login-walled for anonymous viewers — those produce an error row.

- Comments load progressively; very long threads may truncate.

- Private groups and restricted posts are out of scope.

- Use public data lawfully and respect applicable privacy and platform rules.

### FAQ

**Do I need an account or cookies?**

No — the Actor reads public data only. There is no login to configure and no account to risk.

**What happens when a search returns nothing?**

The run completes with zero (or an explicit error) rows. Per-result billing means you are not charged for empty output.

**Can I run it on a schedule?**

Yes — attach an Apify schedule or use the saved tasks to re-run the same inputs daily or weekly.

## CLI example

```bash
echo '{
  "urls": [
    "https://www.facebook.com/facebook/"
  ]
}' |
apify call thirdwatch/facebook-comment-scraper --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,thirdwatch/facebook-comment-scraper"
        }
    }
}
```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
