How It Works
We provide a comprehensive range of REST API endpoints designed to meet your programmatic access needs. Our endpoints accept query parameters or JSON input and return structured JSON responses. Most endpoints require authentication via API key, though we offer /examples endpoints where you can test and explore data without credentials. Documentation includes code examples and integration guides for common use cases. To get started, visit the authentication guide.
