Status JSON

How fresh ClaudeMon's data is: a summary and every source's health in one read. It measures our collection, not whether the labs are up.

GET /api/v1/status

/status.json serves the same JSON. See also the status page and files.

Parameters

assertstringOptional
1 answers 503 instead of 200 when summary.ok is false, so an uptime monitor alerts even if the scheduler stopped.

Every /api/v1 endpoint also takes pretty and format. See views.

lateinteger
Enabled sources that are Late.
staleinteger
Enabled sources that are Stale.
errorsinteger
Enabled sources that are Failing (error).
checks_last_hourinteger
Source checks started in the last hour.
ticks_last_hourinteger

last_tick_atstring or null
When the scheduler last ran.
last_tickobject or null
What the latest scheduled minute recorded, including its terminal status and finished_at when available. Completion order determines recovery even if an older minute finishes last.
