Social Media & Content Scraping

Routes social and content-platform scraping tasks to a maintained scraper, or to the engineering skills if you're building your own.

The reality of social platforms

Most social platforms went client-side rendered years ago, so the raw HTML you fetch is an empty shell. The actual data arrives one of two ways:

• Signed internal XHR/JSON APIs the page calls after load — most platforms expose a search or profile JSON endpoint the front-end hits (Reddit's .json URLs are the well-known public example). Open DevTools → Network → XHR and you'll usually find structured JSON you can call directly.
• Embedded JSON blobs in the initial document — __UNIVERSAL_DATA_FOR_REHYDRATION__ (TikTok profile metadata), ytInitialData (YouTube), __NEXT_DATA__, or JSON-LD. Full structured data, no DOM parsing.

Practical notes that save days:

• Profile / single-URL lookups are far easier than keyword or hashtag search. Hashtag and keyword endpoints are the most heavily defended and frequently require login (Instagram hashtags, in particular). If you only need data for a known handle or post URL, you'll get it more cheaply and reliably than from a search query.
• Engagement metrics live next to the content. Likes, retweets, comment counts, view counts, follower totals and reaction breakdowns are almost always in the same JSON payload as the post itself — you rarely need a second request to enrich them.
• Some targets (TikTok search, anything behind DataDome/Cloudflare) need a stealth browser + residential proxy; many (Twitter syndication, YouTube, Reddit .json) work over plain HTTP, so try HTTP first and only escalate when you actually get blocked.
• Don't log in. Authenticated scraping multiplies both legal and account-ban risk. Stick to public surfaces.
• For RAG / video-understanding pipelines, scrape transcripts rather than audio — captions are text-ready, timestamped, and far cheaper than downloading and transcribing media yourself.
