UptimeMonitoringSsl certificateWebsite statusDevops

Check whether a website is up right now: HTTP status, response time in ms, full redirect chain, and the SSL certificate's validity, issuer and days until expiry. Use when monitoring a site, diagnosing a broken link, or warning that a certificate is about to expire. A site that is down still returns 200 with up:false and the error. Errors: 400 bad or private URL.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
