How this service works
Check if a URL is up: status, latency, redirects, title.
Output
A JSON object indicating whether the URL is up (boolean), its HTTP status code, final URL after redirects, latency in milliseconds, redirect chain, page title, server header, content type, HTTPS flag, and the timestamp the check was performed.
Example use cases
Broken link detection before publish
“Before I publish this blog post, can you check that https://docs.openai.com/api-reference is reachable and returning a 200?”
Monitoring third-party dependency uptime
“Check whether https://stripe.com/docs is up right now and tell me the response time and any redirects it goes through.”
Validating a newly deployed service
“I just deployed my app — can you verify that https://app.mycompany.com is live, uses HTTPS, and what HTTP status it returns?”
Technical details
Endpoint
GEThttps://agent-web-tools.agent-web-tools.workers.dev/v1/check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, lightweight liveness or reachability check for any public HTTP/HTTPS URL without setting up an account or long-term monitoring subscription. Ideal for one-off checks in agent workflows, validating links before sharing, or spot-checking third-party dependencies. Pay-per-call via USDC means no commitment required.
Side effects
- Non-public or internal URLs may be unreachable from the checker's network
- Very slow targets may cause timeout with no latency data
- Malformed or non-http(s) URLs will likely return an error
- Sites blocking cloud/proxy IPs may return unexpected status codes
- DNS resolution failures for non-existent domains
