Latest updates and improvements to FourA
Targets that resolve to a private network range now return a 400 with a clear validation error instead of being forwarded. The check runs before any request goes out and covers reserved IPv4 and IPv6 blocks. If you accidentally pass an internal hostname, you'll see a clean error right away. Same behavior across Single, Proxy Finder, and Browser.
Point any MCP-compatible client at https://mcp.foura.ai/mcp and authenticate with your FourA API key. You will get Single, Proxy Finder, and Browser as tools your LLM can call directly. Works with Claude Desktop, Claude Code, and any other client that speaks the MCP protocol. Setup guide →
The homepage playground has a third tab for Browser, next to Use Proxy and Find Proxy. Sign in and you can run real Browser requests from the dashboard with one click.
Request and response columns now share matching tabs (UI, Body, Headers, Cookies, Raw). Each pane has its own view switcher (JSON tree, HTML tree, text), Expand stretches the response full-width, and Ctrl/Cmd+K opens find-in-pane with next/prev navigation. Copy and Download buttons sit per-pane and grab exactly what's on screen, and the Cookies tab now groups by host with filter, per-row delete, and flag badges.
Every Playground field is now schema-aligned: Browser forces GET, hides the body textarea, and the Raw tab shows the exact JSON that hits the API plus a curl reproducer.
With unblocker: true, Single and Proxy Finder now carry the full unblocker signature all the way to the origin, so anti-bot walls that check it let the request through.
Some Cloudflare sites return 200 OK but inject a background script that issues the real cf_clearance cookie a moment later. Browser used to return the page before that cookie arrived, leaving the jar empty. Now Browser waits for the cookie event, so you get a clean cf_clearance you can replay through Single or Proxy.
You can now compose and send live requests right from your dashboard. Pick one of your API keys, switch between Single, Proxy, and Browser, fill in the URL, headers, and body, then hit Cmd+Enter to fire it. The response panel shows status, timing, and size, plus body, headers, and raw views you can copy or download.
We rolled out unique Open Graph cards for all 30 existing blog posts. Links shared on Discord, LinkedIn, Slack, or Twitter now show a clean, branded preview instead of a generic favicon. New posts get their card generated automatically, with text-fitting that wraps long titles instead of cutting them mid-word.
Embedded screenshots and diagrams in blog posts now switch when you flip the light/dark toggle. No more dark images burning a hole in a bright page, or pale screenshots disappearing on a dark one.
The Older button on the blog used to send you back to page 1. Pagination now lives at /blog/page/N/ URLs with numbered navigation, so you can actually browse older posts. Thanks, Vladimir Petrov.
Browser now runs every request through the JavaScript engine, so Cloudflare challenges and JS-heavy pages render as expected.
The product chip filter (Single, Proxy, Browser) now works on Metrics and Activity too, not just Overview. Pick a product anywhere, and your choice carries across all three pages. One small caveat: the Concurrency scope on Metrics is disabled when a product filter is active, since concurrency isn't broken out by product yet.
Added an explicit acceptable-use clause covering third-party websites, plus a clearer jurisdiction section: Sofia courts with the EU consumer carve-out preserved. Worth a quick re-read if you're working with us at scale.
The dashboard preview on the homepage was cramped on small screens. We fixed the type and spacing, and added tooltips that actually work on touch (hover-only hints don't help a phone).
