Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

updown

updown_add_recipient

Add an alert recipient: an email address, phone number (sms), webhook URL, Slack-compatible incoming-webhook URL, or Microsoft Teams webhook URL. Returns the new (or already-existing) recipient with its id. By default it is selected on ALL existing checks; pass selected=false to add it unattached. Slack/Telegram/Zapier/Statuspage integrations must be set up in the web UI. Requires the read/write API key. updown: POST /api/recipients.

updown_create_check

Add a new monitoring check. The type (http, https, tcp, tcps, icmp) is inferred from the URL scheme; pass type 'pulse' (and no URL) for a cron/heartbeat check. Each check consumes updown credits while enabled. Requires the read/write API key. updown: POST /api/checks.

updown_create_status_page

Create a status page showing the given checks, in order. Returns its token and URL. Requires the read/write API key. updown: POST /api/status_pages.

updown_find_problems

One-call health overview across every check: which are DOWN (since when, error), which have an invalid SSL certificate, which certificates or domains expire within N days, and which checks are paused or muted. Built from GET /api/checks.

updown_get_check

Fetch a single check by token, optionally with the last hour of performance metrics and/or the detailed results of the last 5 requests. updown: GET /api/checks/:token.

updown_get_check_metrics

Get aggregated metrics for one check over a time range: uptime, apdex, timings (redirect/namelookup/connection/handshake/response/total, ms) and request counts by response time. Optionally group by 'time' or by 'host' (monitoring location). Data is hourly (daily after 2 days, monthly after 40 days); the range must span at least one hour. Uptime is not returned when grouping. updown: GET /api/checks/:token/metrics.

updown_list_checks

List all monitoring checks on the account with their status (down, uptime, last_status, error), period, SSL certificate and domain-expiry info. Optionally filter client-side by status or a text match on URL/alias. updown: GET /api/checks.

updown_list_downtimes

List the downtimes of one check, newest first, 100 per page: error, started_at, ended_at, duration (seconds) and a details URL. updown: GET /api/checks/:token/downtimes.

updown_list_node_ips

List updown.io's server IP addresses — e.g. to allowlist the monitors in a firewall. Choose all, ipv4 or ipv6. Public — no API key needed. updown: GET /api/nodes/ips, /api/nodes/ipv4, /api/nodes/ipv6.

updown_list_nodes

List updown.io's monitoring/webhook servers keyed by location code (lan, mia, tor, rbx, fra, cap, hel, sin, tok, syd) with IPv4, IPv6, city, country and coordinates. Public — no API key needed. updown: GET /api/nodes.

updown_list_recipients

List the alert recipients/channels on the account (email, sms, slack, telegram, webhook, zapier, ...). The `id` (e.g. email:3719031852) is what check `recipients` take. updown: GET /api/recipients.

updown_list_status_pages

List the account's status pages: token, public URL, name, description, visibility (public/protected/private) and the ordered check tokens shown. updown: GET /api/status_pages.

updown_update_check

Change a check's settings — URL, period, alias, string match, recipients, headers, locations — or pause/resume it (enabled) or mute its alerts (mute_until). Only the fields you pass are changed. Caution: URLs returned by a read-only key hide basic-auth credentials; re-sending such a URL erases them. Requires the read/write API key. updown: PUT /api/checks/:token.

updown_update_status_page

Change a status page's checks (replaces the list, order respected), name, description, visibility or access key. Only the fields you pass are changed. Requires the read/write API key. updown: PUT /api/status_pages/:token.
