What is this tool?
A live demo of Postman Monitors. Paste any URL and Postman schedules a real monitor for it, then streams each run to a live chart as it happens. No signup, nothing to install. It shows what continuous API monitoring actually looks like before you commit to setting it up.
How long does the monitor run?
This session runs for a limited window. To keep monitoring your API continuously with alerts and history, upgrade to Postman Monitors.
What data will I see on the live chart?
Each run's response time and status code, plotted in real time as the monitor pings your URL. You'll see if response times are stable, spiky, or trending upward.
How is this different from just curling my URL once?
A single test shows one moment in time. This shows a sequence of live runs, so you can see whether the API is stable, degrading, or intermittent. That's the difference between "is it up right now" and "is it healthy over time."
Can I keep monitoring my API after the session ends?
No, this session ends automatically. Postman Monitors runs your API continuously (every 5 min to hourly), stores full run history, and alerts you the moment something breaks.
Does this work for APIs behind authentication?
Not in this tool. Postman Monitors supports Bearer tokens, API keys, OAuth 2.0 with token refresh, mTLS, and signed request patterns.
Can I check my API from different regions?
Not in this tool, it runs from one region. Postman Monitors runs from multiple global regions to catch region-specific latency or downtime.
Do I need to sign up to use this tool?
No signup, no credit card. First result runs in seconds. Sign in only when you want persistent monitoring, alerts, or history beyond the session.
