Real-Time API Uptime & Latency Monitoring
Ensure your REST APIs, JSON endpoints, and web microservices are online, responsive, and returning correct payloads. Verify performance in real-time.

API-Specific Health Checks
Standard ping checkers miss silent database errors. Pingzo provides thorough transaction validation.
Latency Profiling
Slow APIs are as bad as down APIs. We log connection speed, TLS handshake durations, and server processing times for every check request.
Payload Validations
Don't just check the headers. Ensure your API is actually returning correct JSON objects by matching expected response substrings.
TLS & SSL Watchdog
Prevent SSL validation failures from locking users out. Automatically track certificate chains and receive expiry reminders in advance.
Configure Your First API Check in 60 Seconds
No codebase changes required. Set it up entirely from our visual dashboard.
Specify Endpoint
Enter your target API URL and pick the request method: GET, POST, PUT, or DELETE.
Define Payload
Add authorization headers, bearer tokens, or mock JSON body parameters as needed.
Set Thresholds
Determine criteria: specify timeout limits (e.g. 2000ms) and expected body strings.
Choose Channels
Bind alerts to WhatsApp, Discord, Telegram, or Email for immediate notifications.
FAQs
Common technical questions regarding our API uptime checking services.
Can I monitor endpoints requiring custom headers or authorization tokens?
Yes. You can easily add authorization parameters, bearer tokens, API keys, or custom user-agents to your header configurations inside your check settings dashboard.
Do you support POST, PUT, or DELETE request methods?
Absolutely. While standard uptime checkers only execute basic GET requests, Pingzo lets you verify write operations by selecting POST, PUT, or DELETE methods, including custom request body payloads.
What checking interval frequencies are available for APIs?
We support checking intervals starting from 15 minutes on our Free plan, down to 1 minute on our Agency plan. High-frequency checks help you catch transient database timeouts before they escalate.
Do you perform response body payload assertion?
Yes. You can write custom string match rules. If an API returns a 200 OK status code but contains an error payload or empty JSON body, Pingzo will catch it and mark the monitor down.
How are SSL certificate expiration alerts managed?
Pingzo automatically extracts SSL certificate metadata during checks. You will receive an alert 30 days, 7 days, and 1 day before your SSL certificate is set to expire.
