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

checks

list_checks

List all your checks with their current status (up/late/down/pending), last-seen time, ping count, and public status URL.

delete

delete_check

Delete a check and its history, by name or id.

get

get_check

Get one check's current status plus its recent ping history (timestamps and notes).

ping

ping

Send a heartbeat for a named check — call this once per run of your job/agent. If the named check doesn't exist yet it is created automatically (zero setup), so you can just ping the same name every run. Attach an optional one-line `note` (e.g. what the run did) that shows on the public status page. If a ping doesn't arrive within the expected period + grace, the check flips to 'late' then 'down' on its public status page. Returns the check's status and its public status_url.
