Monitor the availability, performance, and integrity of your APIs in real-time.
APIs have become the nervous system of modern applications. Whether it's microservices communicating with each other, mobile apps accessing their backend, or partners integrating your services, APIs are at the heart of every interaction. An unavailable or slow API doesn't just generate an error: it can block an entire chain of services and impact thousands of users simultaneously.
Unlike classic website monitoring, API surveillance requires a specific approach. It's not enough to check that an endpoint responds: you need to validate HTTP status codes, measure response times, authenticate requests, and sometimes even verify the content of JSON responses. An endpoint that responds 200 OK but returns empty or corrupted data is as problematic as an endpoint in error.
MoniTao was designed for API monitoring from the ground up. Our platform supports all HTTP methods, custom headers for authentication, response content validation, and alerts you on anomalies before your users or partners notice the problem.
Monitoring APIs presents unique challenges compared to classic web monitoring:

Deepen your knowledge about API monitoring:
Here's how to configure a monitor for an authenticated REST API with MoniTao:
// API monitor configuration with authentication
{
"url": "https://api.example.com/v1/health",
"method": "GET",
"headers": {
"Authorization": "Bearer YOUR_API_TOKEN",
"Content-Type": "application/json"
},
"expected_status": 200,
"content_match": "\"status\":\"healthy\"",
"timeout": 10000,
"interval": 60
}
// For a POST API with body
{
"url": "https://api.example.com/v1/validate",
"method": "POST",
"headers": {
"X-API-Key": "your-api-key"
},
"body": "{\"check\": \"ping\"}",
"expected_status": 200
}This configuration checks every 60 seconds that the /health endpoint responds 200 and contains the text "status":"healthy". On failure (HTTP error, timeout, invalid content), an alert is sent immediately.
MoniTao offers all the features needed to effectively monitor your APIs:
Yes, MoniTao supports OAuth Bearer tokens. Configure the Authorization header with your access token. For short-lived tokens, create a service token with a long lifetime specifically for monitoring.
Use the content validation feature. You can check that specific text is present in the response, like "status":"success" or "error":false. MoniTao will alert if this text is not found.
For critical APIs (payment, authentication), we recommend checking every 30-60 seconds. For secondary APIs, 2-5 minutes is enough. Adapt according to your SLAs and the impact of downtime.
Configure a POST monitor to your GraphQL endpoint with Content-Type: application/json header and your query in body. Use content validation to verify the response contains "data" and does not contain "errors".
Yes, monitoring requests are regular requests. Plan for this volume in your quotas, or configure a whitelist for MoniTao IPs if your API allows it.
MoniTao automatically performs a double verification before alerting. A single error doesn't trigger an alert. Only errors confirmed by two consecutive checks generate a notification.
APIs are too critical to run without monitoring. An API outage can have cascading effects on all dependent services, from your internal applications to partner integrations. Proactive monitoring is the only way to guarantee the availability and performance your users expect.
With MoniTao, you can monitor your REST, GraphQL, or SOAP APIs in just a few clicks. Authentication, content validation, instant alerts: everything is designed to give you complete visibility into your endpoints health. Start for free and ensure the reliability of your APIs.
