Check if any website is down, from two continents, with uptime history and TLS expiry
Scored across 5 tools
Each tool targets a distinct operation, but check_site and site_history both report current state and user-report counts, which could cause some mis-selection. The descriptions mitigate this by noting that site_history is only for monitored sites and check_site is the fallback for anything else.
Most names follow a clear verb_noun pattern: check_certificate, check_site, list_monitored_sites, list_outages. site_history breaks the pattern by omitting a verb, though the inconsistency is minor and the names remain readable.
Five tools are well-scoped for a website status and monitoring service. Each earns its place: live checks, certificate checks, monitored inventory, current outages, and history.
The tool surface covers the main user needs: live status, certificate expiry, monitored-site inventory, ongoing outages, and historical uptime. There are no significant missing operations for a read-only status service.
Reads the HTTPS certificate of a public domain and reports days until expiry, the expiry date and the issuer.
Inputs: domain (required). Returns: state, domain, issuer, validTo, +1 more
Live up/down check of any public website from an independent server (Singapore; Boston for sites that geo-block Singapore). Returns a one-sentence verdict plus status code, latency, resolved IP, redirect target, the view from the other region when available, and how many users reported problems in the last hour. Results are cached 30 s per domain.
Inputs: domain (required). Returns: ip, up, tls, url, +15 more
The 634 sites checked every 5 minutes, grouped in 17 categories. Without arguments returns the category list with counts; filter by category or a text query to get domains (at most 200 per call).
Inputs: query, category. Returns: Without arguments: total + categories. With category or query: total, matched,…
Lists the monitored sites (634 across 17 categories) that are confirmed down right now: two consecutive failed checks from their home region and no other region seeing them up in the last 15 minutes. Optional category filter.
Inputs: category. Returns: asOf, down, category, monitored
Uptime percentage over 24 h and over the requested window (up to 7 days), the list of outages in that window, when the site was last seen down, the current state and user-report counts. Only for monitored sites (see list_monitored_sites); use check_site for anything else.
Inputs: domain (required), days. Returns: url, days, name, domain, +10 more
