About Kit's Kit API
Kit's Kit API manages email lists, broadcasts, and automations for creator-focused audiences via Kit. Kit (formerly ConvertKit) was founded in 2013 and focuses on email tools for creators and bloggers.. The Kit API is used by developers worldwide for subscriber management, email sequences, broadcast sending, automation rules, landing pages.
Probecast monitors the Kit API from 4 global regions (US West, US East, Europe, Asia Pacific) every 300 minutes, tracking uptime, latency and regional availability. Our real-time monitoring helps developers and teams understand the current health of Kit's Kit API and get alerted the moment service degrades.
Why monitor Kit API?
If your product depends on Kit API for critical features, an outage on Kit's side is an outage on your product. Probecast detects Kit API incidents as they start, giving you time to communicate with customers, fall back to alternative services or pause background jobs gracefully.
