dev.workers.watchpup.watchpup/watchpupFree uptime monitoring: HTTP/TCP/TLS/DNS + MCP server checks, cron heartbeats, status pages, alerts.
Tools · 12
Check any public URL RIGHT NOW: is it up, HTTP status, response time in ms. With kind:"mcp" it instead performs a real JSON-RPC initialize handshake against a streamable-HTTP MCP server endpoint and r…
List all monitors on the account: current up/down status, kind, target, interval, last check. Optionally filter by tag.
Full detail for one monitor: status, config, 24h latency percentiles and trend (http/tcp), SLA budget if a target is set. Heartbeat monitors include their ping_url and ping_email.
Create a monitor. kind=http (needs url), tcp (target "host:port"), tls (target host[:port] — cert-expiry watch), domain (target — registration-expiry via RDAP), dns (target + rtype A/AAAA/MX/... , opt…
PATCH any monitor field: name, url, target, interval, expect, keyword, slow_ms, grace, cron, tags, sla_target, renotify, channels (alert routing)... Pause with {"status":"paused"}, resume with {"statu…
Permanently delete a monitor and all its check history, events and rollups. Cannot be undone.
Downtime incidents (ongoing and resolved) across all monitors: start, duration, cause, acknowledgement, notes.
Mark an ongoing incident as "someone is on it" — pauses still-down reminder alerts for that monitor until recovery. Set un=true to un-acknowledge (re-arms reminders).
Attach/replace a note (max 500 chars) on an incident. Notes publish with the incident on public status pages, their JSON and the Atom feed. Empty string clears.
Alert delivery channels on the account (email / webhook / Discord / Slack / ntfy / Telegram), their verification state and delivery health.
Machine-readable state of any public Watchpup status page by slug: per-monitor status, uptime, incidents last 30d. No API key needed.
Who am I: account email, monitor count/limit, plan limits. Good first call to verify the API key works.
