Monitor whether your API works — not just whether it responds.
Execute full REST checks with custom payloads, authentication headers, and granular JSONPath assertions. Validate response status codes, payload structures, and latency SLAs.
$.success == true$.data.session_id exists$.data.amount == 999Deep API Inspection Capabilities
Test complex microservices, authentication gateways, and third-party APIs.
All HTTP Methods
Full support for GET, POST, PUT, PATCH, and DELETE endpoints with custom request bodies.
Headers & Authentication
Pass Bearer tokens, API keys, Basic Auth, and custom headers securely on every test ping.
JSONPath Assertions
Assert values, types, nested arrays, and ensure required keys exist in the returned JSON.
Latency Thresholds
Trigger alerts if response times exceed your SLA threshold, even when HTTP status is 200.
Workflow Escalation
Dispatch payload failure details directly into GitHub issues or on-call Slack channels.
Automatic Retries
Configurable retry attempts prevent false alarms from transient edge network hiccups.

A 200 response doesn't always mean your API works.
Silent failures happen when an API returns HTTP 200 OK but the body contains an empty payload, database connection error, or missing authentication token. Our assertion engine inspects the actual response data.
- JSONPath Assertions — Extract keys and test nested values with precision.
- Custom HTTP Headers & Auth — Support Bearer tokens, Basic Auth, and custom payloads.
- Latency SLA Thresholds — Detect performance degradation before servers crash.
Simple, transparent plans for every stage.
No hidden fees. No complicated usage math. Choose the duration that fits your project.
