GUIDED SCENARIOS

Mock API scenarios

Realistic fictional APIs with pagination, authentication, errors, rate limits and latency. Pick a scenario, follow the guided steps or explore freely.

Simulation only. These scenarios run on a mock server inside your browser. They never contact a real API, and tokens and keys shown are fake.
