Check if a URL is reachable

Send a request to any URL and instantly see if it's up, what status it returns, where it ultimately resolves, and how long it took.

GET /api/url-check

Try it

Enter a URL

{
  "reachable": true,
  "status": 200,
  "final_url": "https://vercel.com/",
  "response_time_ms": 123,
  "error": null
}

What it returns

•reachable - whether the URL responded without a network error
•status - the HTTP status code of the final response
•final_url - the URL after following all redirects
•response_time_ms - total time for the request in milliseconds
•error - error code if the request failed, null otherwise

Use cases

•Validate user-submitted URLs before saving them
•Monitor webhooks and integrations for uptime
•Clean scraped datasets by filtering broken links
•Check if an API endpoint is responding before sending requests
•Verify redirect chains are behaving correctly
