API Status Checker
Real-time
Check if popular AI and developer APIs are reachable from your browser. Some APIs block cross-origin requests (CORS) — that means the server is up but the browser cannot read the response.

How This Works
This tool sends requests from your browser to public API endpoints. Browsers enforce CORS (Cross-Origin Resource Sharing) policies, so some APIs that are fully operational will show as "CORS Blocked" because they don't allow browser-based cross-origin requests. A CORS-blocked result still means the server is responding — it just doesn't permit direct browser access.
