URL Status Checker — bulk HTTP status & redirect checker

For SEO teams and web developers who need to verify a long list of URLs. Get the HTTP status, the full redirect chain, the final URL and the response time for each — for site migrations (verify your 301 map), SEO audits and broken-link checks. $0.30 per 1,000 URLs checked. Leave the input empty for a free demo.

Use cases

• Verify a 301 redirect map after a migration

• Find broken links (404, DNS failures, timeouts) in a URL list or sitemap export

• Detect redirect chains and loops, and http-to-https redirects

• Checks only the URLs you provide — it does not crawl pages or follow links

• Redirects are followed manually (up to 10) and every hop is recorded: redirectChain

• Tries HEAD first and falls back to GET when the server answers 405/501

• DNS failures, timeouts and connection errors are reported as error (status null) instead of failing the run

• Input as a list, or from another Actor's dataset (choose the URL field)

• Polite by design: max 2 connections per host, at least 0.2 s between requests to the same host, up to 100,000 URLs per run

• Status counts are saved as SUMMARY in the key-value store

• Rows that never reach the network (invalid_url, blocked_private_address) are not charged. Free demo on empty input (not charged)

• Safe by design: URLs that resolve to internal addresses (localhost, private ranges, link-local such as 169.254.169.254, IPv6 loopback/unique-local) are never contacted, including redirect targets — reported as blocked_private_address

Input

{ "urls": ["https://example.com/old-page", "http://example.com"], "followRedirects": true, "timeoutSecs": 15, "concurrency": 5 }

Or { "datasetId": "<dataset id>", "urlField": "url" }.

Output

{
  "url": "http://example.com/old", "finalUrl": "https://example.com/new", "statusCode": 301, "finalStatusCode": 200,
  "ok": true, "redirectCount": 2,
  "redirectChain": [{"url": "http://example.com/old", "status": 301}, {"url": "https://example.com/old", "status": 301}, {"url": "https://example.com/new", "status": 200}],
  "isHttpsRedirect": true, "responseTimeMs": 412, "contentType": "text/html; charset=utf-8", "contentLength": null,
  "error": null, "checkedAt": "2026-10-18T09:00:00+00:00"
}

ok is true when the final status is 2xx. For unreachable URLs statusCode and finalStatusCode are null and error is e.g. dns_failure, timeout, too_many_redirects, redirect_loop, invalid_url or blocked_private_address.

Notes

Some sites block automated requests or answer HEAD/GET differently than a browser; results reflect what a plain HTTP client sees. Set a custom userAgent if needed, and only check URLs you are allowed to request.
