Use case
API Uptime Monitoring
Pulsy is a fully-managed uptime monitor for your APIs and HTTP endpoints. It sends scheduled GET, HEAD, or POST requests, checks the response status and timing, watches TLS expiry, and alerts you when an endpoint starts failing.
The problem
- A broken API endpoint can pass a homepage check while your integrations quietly fail.
- Per-check SaaS pricing punishes teams that run many small services and endpoints.
- Certificate and uptime checks bolted on from separate tools drift out of sync.
How Pulsy helps
- Monitors each endpoint with the right method (GET/HEAD/POST) and expected status code, not just a homepage ping.
- Records response time so you catch a degrading API before it fully fails.
- Watches TLS expiry on HTTPS endpoints alongside up/down status.
- Alerts through email, webhook, Slack, Discord, or Telegram and groups failures into incidents.
Frequently asked questions
- Can Pulsy monitor an API endpoint?
- Yes. Add the endpoint URL as a monitor, choose GET, HEAD, or POST, set the expected status code and timeout, and Pulsy checks it on your schedule, tracking response time and up/down status.
- Does API monitoring include response time?
- Yes. Every check records response time in milliseconds, so you can see an endpoint slowing down before it starts returning errors.
- Can I monitor many endpoints affordably?
- Yes. Pulsy uses flat plans rather than per-check pricing, so watching many endpoints does not multiply your bill.
