I built MCP Sub-50ms fetches for protected websites

I built Karon. A lot of "AI agent infrastructure" feels backwards to me: lots of abstraction, lots of demos, and not much that actually helps an agent reach a real page on the live web. So I built something simpler: an API that fetches pages that normal HTTP clients often fail to reach, plus an agent-friendly endpoint that returns clean markdown/text instead of raw HTML. The basic flow is: The first request clears the WAF challenge (3–10s) Session state gets cached Subsequent requests to the same site reuse the session (~45ms) /v1/agent/browse returns cleaned content for agent workflows What I wanted was not a "platform" pitch, just infrastructure that is immediately usable. Available now: Free tier No credit card Failed requests are free Google sign-in for self-serve API keys MCP package for agent workflows: pip install karon-mcp /v1/agent/browse for markdown / text extraction Examples: Raw HTML: curl -X POST https://api.karonlabs.net/v1/fetch \ -H "Authorization: Bearer YOUR_KEY" \ -
