URL Status and Redirect Chain Checker
x402
URL Status and Redirect Chain Checker is a paid API for AI agents from flat-rate-llm.kikoribera03.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).
Checks a URL's HTTP status code, full redirect chain with per-hop codes, final URL, HTTPS enforcement, content type/size, and security headers — without downloading the page body.

How this service works
60 paid endpoints with no metering, no API key and no account. Each endpoint has one flat price per call, whatever the size of the request: LLM completions with automatic failover across several large models, read-only EVM tooling over Base, Ethereum, Polygon, Arbitrum and Optimism, and pure crypto utilities that touch no network.
Output
Returns a JSON object with: ok (boolean success), url (original URL), hops (number of redirects), chain (array of hop objects each with URL and status code), status (final HTTP status), finalUrl (landing URL after all redirects), elapsedMs (request duration), redirected (boolean), contentType (MIME type at final URL), and finalScheme (http or https).
Example use cases
Audit broken links in a list
“I have this link from my newsletter — https://old-promo.example.com/sale — can you check if it's still live, what status it returns, and whether it redirects anywhere before landing?”
Verify HTTPS enforcement on a site
“Does https://myshop.example.com properly end on HTTPS after all redirects, and does the server send any security headers like HSTS or X-Frame-Options?”
Trace a short URL before sharing
“Before I post this link — https://t.co/abc123XYZ — can you trace exactly where it redirects, show me each hop with its status code, and confirm the final destination URL?”

Endpoint
POSThttps://flat-rate-llm.kikoribera03.workers.dev/v1/web/statusWhen to prefer
Use this endpoint when you need lightweight link health checks — HTTP status, redirect hops, and security headers — without downloading the full page body. It is ideal for auditing lists of URLs one at a time, verifying redirect destinations, checking HTTPS enforcement, or inspecting server security posture. Prefer it over a full web scraper when page content is irrelevant and speed matters. No API key or account is needed; a flat $0.005 per call makes it practical for batch link auditing jobs.
Side effects
- Private or loopback IP addresses are refused with an error
- Some servers reject HEAD requests; retry with method=GET
- Unreachable or DNS-failing URLs return an error with ok=false
- Very long redirect chains may time out
- Non-HTTP/HTTPS schemes (ftp, mailto, etc.) are not supported
