Pixefy API or CLI

Have the ability to call an API providing the URL and the device and getting screenshots so can test a site using an LLM e.g. Codex or Claude Code - say you create an app or create a website you may want to test a battery of common sizes and devices to see how it looks and then get the output and then have another AI analyse to see if anything is out of place - too squished or score each site out of 10 for example..
