The End of APIs: Why Vision Agents Are the Future of Scraping

Note: This approach is inspired by the "Visual Scraping" meta discussed by builders like Ahmad Osman.

We are witnessing the death of the public API.

Twitter (X) charges $100/mo for a "Basic" tier that barely lets you read 10k posts. Reddit locked down. LinkedIn will ban you if you breathe wrong.

For a long time, the alternative was DOM Scraping (BeautifulSoup, Selenium). You'd hunt for div.css-1dbjc4n and pray Elon didn't push a frontend update that randomized the class names.

But there is a third way. And it's how we win.

The "Human" Approach (Vision Scraping)

When you look at a tweet, you don't inspect the HTML source. You just... see it. You see the avatar, the bold text for the name, the grey text for the handle, and the content below it.

With Multimodal LLMs (like Gemini 1.5 Pro and GPT-4o), our agents can now "see" too.

The Strategy:

Navigate: Use a stealth browser (like Playwright with stealth-plugin) to load the page.
Snapshot: Don't grab the HTML. Grab a screenshot (.png).
Process: Send that screenshot to a Vision Model.
Prompt: "Extract all tweets from this image into this JSON schema: { handle, text, likes }."

Why This Works

Anti-Fragile: The HTML class names can change 50 times a day. As long as the site looks like Twitter to a human, it looks like Twitter to the AI.
Bypass Anti-Bot: You behave exactly like a user. You scroll, you pause, you look. You don't bombard the server with 1000 requests/sec.
Context Aware: Vision models understand "This is a promoted tweet" or "This is a reply" instantly based on visual cues (like the little 'Ad' badge) that are often buried in obscure attributes.
