Test what your API actually returns.
Not just that it responds.
Go beyond 200 OK. Assert JSON values, array lengths, response shape and headers; validate auth and token flows; and track latency across your critical endpoints.
GET /api/v2/users
Beyond the status code.
A 200 OK only tells you the server answered. Assert the shape, values, and headers of real API responses, and validate the auth flows that protect them.
Deep response assertions
Write fine-grained assertions against the JSON body, headers, and status of every response. Catch the subtle bugs that only appear when your API starts returning empty arrays, wrong field types, or missing keys.
- Assert specific JSON values and array lengths
- Validate required fields and response shape
- Check response headers and content types
Auth & token flows
Test your authentication layer end-to-end. Issue tokens, use them on protected routes, and verify that bad tokens are correctly rejected, all on a schedule, so a broken auth flow never catches you by surprise.
- Test secured endpoints with scoped credentials and custom headers
- Validate token creation and refresh behavior
- Verify authorization rules reject bad tokens

Latency & degradation
A slow API is an unreliable API. Track the full latency chain (DNS, connect, TLS, and TTFB) so you can spot where time is being lost and catch gradual regressions before they cross your SLA.
- Alert on p95 latency thresholds
- Detect gradual degradations early
- Separate DNS/connect/TTFB timings
Catch the failure your status check misses.
Validate real API behavior in under a minute.
