Could you build this?
Partial Wrapping an LLM to parse HTML into JSON is trivial, but an enterprise extraction API must reliably render JavaScript-heavy dynamic single-page applications at scale while evading bot blockers on hostile domains.
What it would actually take: The system requires a massive fleet of managed headless browser instances (Chromium with CDP) optimized for low latency and distributed across residential proxy networks with fingerprint spoofing to bypass Cloudflare/Akamai. The technical bottleneck is fast DOM tree simplification, streaming extraction, and guaranteed JSON schema adherence without running into massive memory overhead or timeouts. Requires expertise in browser internals, distributed systems, and anti-scraping countermeasures.
