Deep API Health Checks
API Uptime Monitoring for Developers
HTTP 200 is not a health check. upti.my validates your APIs actually work. We check response bodies, headers, latency, and authentication flows.
Why API Monitoring Requires More Than Ping
Your API can return 200 OK while being completely broken. A database connection fails, and the endpoint returns an empty array. Auth is misconfigured, and everyone gets "null" for their profile. The service is up, but the API is useless.
Response Validation
Check that API responses contain expected data, not just status codes.
Multi-Step Flows
Test complete user journeys: login → fetch data → verify.
Auth Testing
Verify protected endpoints reject unauthenticated requests.
Protocol Support
HTTP, GraphQL, gRPC, TCP, DNS, SSL. All with native support.
Common API Monitoring Mistakes
Most teams set up basic monitoring and call it done. Then they find out about outages from their users instead of their tools.
- ✗Only checking /health while the main endpoints are broken due to a database issue
- ✗Ignoring response bodies because an empty array is still a 200 OK
- ✗Skipping auth endpoints so login fails, but the API "works"
- ✗No latency thresholds so 5-second response times aren't caught until users complain
How upti.my Monitors APIs Properly
upti.my treats API monitoring as first-class. Every check validates what matters: response content, timing, headers, and protocol-specific behaviors.
JSON Assertions
Validate specific fields in JSON responses with JSONPath expressions.
Header Validation
Check for required headers, CORS, and cache controls.
Latency Thresholds
Alert when response times exceed acceptable limits.
Multi-Step Checks
Chain requests and use responses in subsequent calls.
Getting Started
Set up API monitoring in the dashboard:
- 1
Create a Monitor
Click "New Monitor" and select your protocol: HTTP, GraphQL, gRPC, TCP, DNS, or SSL.
- 2
Enter Your Endpoint
Add your URL, authentication headers, and any request body needed.
- 3
Add Assertions
Define what success looks like: status codes, response body fields, latency limits.
- 4
Set Alert Channels
Connect Slack, Discord, PagerDuty, or webhooks. Get notified your way.
Frequently Asked Questions
What makes API monitoring different from website monitoring?
API monitoring goes beyond checking if a URL returns 200 OK. It validates response bodies, headers, authentication, response times, and can execute multi-step sequences to test complete user flows.
Can I monitor authenticated API endpoints?
Yes. upti.my supports Bearer tokens, API keys, Basic auth, OAuth 2.0, and custom header-based authentication. Credentials are encrypted and never logged.
How do I monitor GraphQL or gRPC APIs?
upti.my has native support for GraphQL queries/mutations and gRPC services. You define the query or method to call, and we validate the response matches your expectations.
Can I chain multiple API calls together?
Yes. Multi-step checks let you authenticate, hit an endpoint, then verify side effects. This simulates real user behavior and catches integration failures.
What happens when an API check fails?
Failed checks trigger immediate alerts via your configured channels. The incident includes the full request/response details, timing, and which assertion failed.
