## Machines

- POST https://innernetcorp.com/machines/render - Screenshot / PDF renderer ($0.01/call). Render any public URL, or raw HTML you provide, into a PNG/JPEG screenshot or a PDF using a real headless browser. Useful when an agent needs pixels: previews, archives, visual checks, reports.

Extract the readable article from a public URL (or raw HTML) and return it as clean Markdown with title and byline. Reader-mode for agents: strips nav, ads and boilerplate.
