r/SideProject on Reddit: I built a free API to instantly extract structured JSON from any webpage (even ones with JavaScript, CAPTCHAs, and anti-bot tech)
April 28, 2025 -

I just launched a super simple, free API that lets you pull structured data from any webpage with one call.

How it works:

You just open your browser to:

https://instantapi.ai/<the-url-you-want>

Example:

https://instantapi.ai/https://www.amazon.com/Cordless-Variable-Position-Masterworks-MW316/dp/B07CR1GPBQ/

It’ll automatically parse the page and extract structured data.

If you want raw JSON (for app integrations, scraping pipelines, feeding into LLMs, etc.), just set Content-Type: application/json.

Example using cURL:

curl --location 'https://instantapi.ai/https://www.amazon.com/Cordless-Variable-Position-Masterworks-MW316/dp/B07CR1GPBQ/' --header 'Content-Type: application/json'

Tech highlights:

  • Full browser rendering (handles JavaScript-heavy sites)

  • CAPTCHA solving (hCaptcha, reCAPTCHA, etc.)

  • Proxies + stealth fingerprinting to bypass anti-bot systems

  • GenAI-based data extraction... no CSS selectors needed

  • Custom HTML rendering + compression engine to keep speeds reasonably fast despite full page rendering + AI parsing

Why I built this:

I’m tired of seeing people stuck using the old, fragile ways of scraping... CSS selectors, constant breakage, expensive custom setups. I wanted to show what the future of scraping looks like: data-first, AI-powered, and effortless.

This free version is meant for small operators, indie devs, and hobbyists... people who just need a clean, reliable tool without jumping through hoops or racking up huge bills. I’m not planning to limit it unless someone starts abusing it with massive-scale usage (e.g., enterprise-level scraping at my expense).

To be totally upfront: I do offer a much more powerful, customizable paid version for commercial use cases. But I think basic, modern scraping should be accessible to everyone, and that’s what this free version is here for.
