API Monitoring
Real-time availability monitoring. Track HTTP status codes, measure response latency, and validate JSON payloads across your entire microservices architecture.
Request Methods & Metrics
PingSled executes configurable HTTP requests against your endpoints every 60 seconds. We capture status codes, measure server processing time, and log header payloads for complete transparency.
HTTP Status Code Tracking
Automatically flag 4xx and 5xx responses. Configure custom success ranges for maintenance windows or staged rollouts. Get instant alerts when your /api/v1/auth/login endpoint returns a 503 Service Unavailable.
Response Time Measurement
Track DNS resolution, TCP handshake, TLS negotiation, and server processing time. Baseline your webhook delivery latency and receive warnings when TTFB exceeds 250ms across AWS us-east-1 check nodes.
Custom Header Inspection
Verify that critical headers like X-Request-ID, Cache-Control, and Strict-Transport-Security are present and correctly formatted. Fail checks if your CDN drops security headers during cache purges.
JSON Payload Validation
Beyond simple uptime, PingSled inspects the actual data your API returns. We parse JSON responses, verify schema compliance, and assert specific field values to catch silent data corruption before your users do.
Schema Draft-07 Compliance
Upload your OpenAPI 3.0 or JSON Schema definitions. PingSled validates every response against your contract. Automatically detect when a new deployment introduces breaking changes to your /products endpoint structure.
Field-Level Assertions
Define expected values for critical paths. Check that data.status equals active, verify that meta.total_count remains above zero, and ensure timestamp fields follow ISO 8601 formatting across all paginated results.
Webhook & Payload Testing
Simulate inbound webhook deliveries with custom JSON bodies. Validate that your signature verification logic processes events correctly and returns the expected 200 OK with a matching event ID in the response body.
