What can you build with API Endpoints?
API Endpoints is a Developer Tools API. Developers commonly use developer tools APIs for:
- automating code review and quality checks
- integrating CI/CD pipelines and build systems
- managing feature flags and A/B tests
- monitoring errors and application performance
- generating and validating test data
No authentication required. This API is open — no signup or key needed. Ideal for quick prototypes and public-facing features. API Endpoints is free to use, making it a low-risk choice to experiment with.
