Introducing APIAssert#

We're excited to announce APIAssert, a new approach to API monitoring built specifically for developers who need more than just uptime checks.

The Problem with Traditional Monitoring#

Most API monitoring tools check one thing: is your endpoint returning a 200 status code?

But here's the thing — 200 OK doesn't mean everything is OK.

Your API could return a 200 with:

• An empty array when it should have data
• A malformed JSON response
• Missing required fields
• Stale cached data
• Incorrect values

Traditional monitors miss all of this. You find out about these issues when your users complain.

Response Validation Changes Everything#

APIAssert lets you validate the actual content of your API responses:

{
  "assertions": [
    { "path": "$.status", "equals": "active" },
    { "path": "$.users", "exists": true },
    { "path": "$.users[0].email", "matches": "/@/" },
    { "responseTime": { "lt": 500 } }
  ]
}

Now you'll know immediately when:

• A required field is missing
• A value doesn't match the expected format
• Response times exceed your thresholds
• Any part of your API contract is broken

Multi-Region Monitoring#

APIs behave differently depending on where you call them from. A CDN misconfiguration, a regional database issue, or a routing problem can cause failures that only affect certain users.

APIAssert monitors from 6 regions simultaneously:

• US East (Virginia)
• US West (Oregon)
• EU West (Ireland)
• EU Central (Frankfurt)
• AP South (Mumbai)
• AP East (Singapore)

Get Started in Minutes#

1. Sign up for free (no credit card required)
2. Add your first endpoint
3. Configure your assertions
4. Choose your regions and check frequency

You'll have comprehensive API monitoring running in under 5 minutes.
