Endpoint Details

Error Simulation

Build more resilient applications by simulating failure conditions in a controlled and predictable way. This endpoint helps you understand how your system behaves when things go wrong, allowing you to validate error states, fallback paths, and recovery flows without relying on real outages.

Core Capabilities

  • Realistic Behavior: Generate structured failure responses that reflect common issues encountered in real-world environments.
  • Consistent Results: Reproduce the same scenarios across development, testing, and review, making it easier to diagnose problems and verify fixes.
  • Flexible Scenarios: Simulate a variety of failure patterns to test how your application reacts under different conditions.
  • Scalable Testing: Create single failures or full batches to validate UI lists, logs, dashboards, and monitoring tools.

Use Cases

  • Previewing UI error states before they occur in production.
  • Validating retry mechanisms and fallback logic.
  • Testing resilience during degraded performance or partial outages.
  • Creating consistent examples for demos, documentation, or debugging.

Fun Fact

Simulated errors behave just like the real thing, giving you a safe environment to explore failure paths and improve your application's reliability without ever triggering a real incident.
