What Is API Monitoring?

API monitoring is more than just checking for a 200 OK status. It's about ensuring your business logic is intact and your performance SLAs are being met.

Beyond the 200 Status Code

Many developers make the mistake of only monitoring HTTP status codes. However, an API can return a 200 OK while actually returning an empty array or an error message in the JSON body.

What You Should Validate:

• JSON Schema: Does the response have the expected keys?
• Data Types: Is the price field a number or a string?
• Latency: Is the response coming back within 200ms?

Implementing Assertions

With Monitor Hub, you can write assertions that run on every check:

{
  "status": 200,
  "body": {
    "success": true
  },
  "headers": {
    "content-type": "application/json"
  }
}

Global Latency Tracking

Your API might be fast for you, but what about your users in Tokyo or London? Monitor from multiple geographical regions to identify regional bottlenecks.
