Practice app · Acme REST API
A live REST + GraphQL API with auth, validation, pagination, rate limiting and an interactive request console.
Your starter code already declares BASE_URL — call the API relative to it.
Objective
Measure client-side response time and assert it against a budget, including a deliberately slow endpoint.
Your task
- 1Time GET BASE_URL + "/users/1" and assert it completes in under 2000 ms.
- 2Time GET BASE_URL + "/slow?delay=500" and assert it takes at least 500 ms.
- 3Assert the slow body is { delayedMs: 500 }.
Acceptance criteria
- GET /users/1 returns 200
- GET /slow returns 200
- At least 3 assertions pass
