Scaling AI Web Scraping & HTML to JSON Extraction on a Budget
Raw web pages contain thousands of useless CSS classes and script tags. Sanitizing HTML before prompting reduces input token consumption by 70%.
Typical monthly workload
- Input tokens
- 25,000,000
- Output tokens
- 3,000,000
- Requests / day
- 5,000
Illustrative estimate. Adjust the sliders below to match your own volume.
Recommended setup
Convert raw HTML to clean markdown with readability algorithms before sending to LLM; enforce strict JSON schemas.

Computed from list prices and the workload above (25,000,000 input and 3,000,000 output tokens per month), with no caching or batch discounts. Real bills vary.
How to cut this cost
- Pre-process with Readability / Turndown
Strip navbars, footers, and scripts locally in Node.js/Python before passing HTML to the model.
