Social Media Scraper Skill

Query Facebook posts via RapidAPI and scrape LinkedIn profiles via Bright Data. All logic runs as safescript with no subprocess access.

Pass secrets via secretMapping:

{ "rapidApiKey": "RAPIDAPI_KEY", "brightDataToken": "BRIGHTDATA_TOKEN" }

Getting API Keys

RapidAPI

Used by facebookPosts and youtubeSubtitles.

When a RapidAPI key is missing, explain clearly that this is an external API key the owner needs to create in RapidAPI, not a password for Facebook or YouTube. Do not say "if you already have one" as the main path; most owners will need to create it now. Give the setup steps plainly and in the user's language, and include the direct subscription link the user needs to open.

Good explanation:

To pull Facebook post data reliably I need access to a RapidAPI provider. RapidAPI is a marketplace for APIs; you create a free RapidAPI account, subscribe to the Facebook Scraper v3 API at https://rapidapi.com/restyler/api/facebook-scraper3, copy your RapidAPI key, and send it here. I will store it securely as a bot secret named RAPIDAPI_KEY and use it only for these API calls.

Do not present browser scraping as an equivalent fallback when the task needs structured Facebook engagement data. Facebook often blocks browser automation; for reliable post/engagement analysis, guide the owner through RapidAPI setup.

1. Go to rapidapi.com and create a free account.
2. Subscribe (free tier) to the APIs you need:
   • Facebook Scraper v3 — for Facebook posts
   • YouTube Media Downloader — for YouTube subtitles
3. Copy your API key from the RapidAPI dashboard.
4. Add it as a bot secret (e.g. name RAPIDAPI_KEY) with no host restrictions.

When the owner sends the key, immediately store it with the secret-storage tool as RAPIDAPI_KEY. Then call the relevant tool with secretMapping: { "rapidApiKey": "RAPIDAPI_KEY" } instead of asking for the key again.

Bright Data

Used by startLinkedInProfileScrape and getLinkedInProfileSnapshot.

1. Go to brightdata.com and create an account.
2. Get your API token from the Bright Data dashboard.
3. Add it as a bot secret (e.g. name BRIGHTDATA_TOKEN) with host api.brightdata.com.

Tools

• facebookPosts — Search or get Facebook posts. Pass query and/or groupId.

• startLinkedInProfileScrape — Start a LinkedIn profile scrape (max 10 URLs). Returns a snapshot_id for polling.

• getLinkedInProfileSnapshot — Fetch status/result of a pending snapshot.

• youtubeSubtitles — Fetch SRT subtitles for a YouTube video URL.

Example usage

import { facebookPosts } from "./scripts/social-media-scraper.ss";

export const myTask = async () => {
  const result = await facebookPosts(
    process.env.RAPIDAPI_KEY,
    "deno programming",
    "",
    "",
  );
  console.log(result);
};

Facebook

The facebookPosts function accepts:

• rapidApiKey — RapidAPI key
• query — Search query (empty string to omit)
• groupId — Facebook group ID (empty string to omit)
• sortingOrder — Sorting order for group posts, e.g. CHRONOLOGICAL

At least one of query or groupId must be non-empty.

LinkedIn

Two-step flow:

1. Call startLinkedInProfileScrape(brightDataToken, urls) with up to 10 URLs.
2. If the response contains a snapshot_id, call getLinkedInProfileSnapshot(brightDataToken, snapshotId) to check progress. Repeat until status is "ready" or "failed".

Valid LinkedIn URL format: https://(www.)linkedin.com/in/<username>/

YouTube

Fetch subtitles for a single YouTube video:

• youtubeSubtitles(rapidApiKey, url) — Returns SRT subtitle text for a YouTube video URL. The URL must contain a video ID (e.g. https://youtube.com/watch?v=abc).
