API Monitoring for SaaS Teams

As a SaaS provider, you earn money from availability. Every 500 on your API costs trust, every SLA breach costs real money. live24h monitors health endpoints, validates JSON responses, posts authenticated requests and reports outages before your customer files the first support ticket.

The Problem: SLA Promises Without Proper Monitoring are Bluff

Your API is your product. And yet hardly anyone actually monitors it properly:

  • “200 OK” isn’t enough – if the response body suddenly contains {"error": "db down"}, the status code is lyingly green
  • No multi-region checks – if eu-central is dead, your team in us-east never notices
  • No monitoring behind auth – public endpoints reachable, the authenticated part is dead
  • Incident communication is chaos – customers are stuck, your CS team doesn’t know exactly what’s going on
  • SLA reports via Excel – embarrassing in an audit

The Solution: API Checks That Test Real Behaviour

live24h makes real API requests – not just pings:

  • Ping health endpoints – classic entry, response time and status code in view
  • JSONPath assertions – check $.status == "ok" and $.database.healthy == true in the body, not just 200 OK
  • Send POST body – authenticated POST/PUT requests with configurable body
  • Custom headersAuthorization: Bearer ..., X-API-Key, tenant headers, anything goes
  • Response-time SLOs – P50 / P95 in view, alert on degradation
  • Multi-region checks – eu-central, eu-west, eu-north, us-east, us-west, ap-southeast
  • HTTP status whitelist – 2xx/3xx as green, or a tighter definition like “only exactly 204”

Every check is manageable via API – ideal for your DevOps pipeline.


Features for Professional SaaS Communication

Incident Timeline

For every incident you see the full timeline: when was it detected, from which regions, how long did it last, who acknowledged. The basis for post-mortems and honest root-cause analyses.

Public Status Page

A professional status page on your own domain (status.your-api.com) with:

  • Current status of all services (split by component)
  • Historical incidents with duration and reason
  • Announce planned maintenance windows
  • Subscribe via email, RSS or webhook
  • Trust that you can link to from your pitch deck

PDF Reports for SLA Conversations

A clean monthly report per check (or per tenant workspace): uptime percentage, incidents, average response time, region comparison. Perfect for enterprise customer meetings.

Multi-Tenant Organisation

When you monitor multiple products or customer environments, checks can be organised into workspaces – every customer with their own status page and own reports.
