LeakZero OpenAPI Specification
Complete API specification in OpenAPI 3.0 format for client generation
leakzero-openapi-spec.json
Complete API specification with all endpoints, schemas, and examples
Always Up-to-Date
Our OpenAPI specification is automatically generated from the live API, ensuring 100% accuracy and immediate availability of new features and endpoints.Why Use OpenAPI Client Generation
Development Velocity
Generate complete, type-safe API clients in minutes instead of hours. Eliminate manual API integration work and focus on your core security logic.
Zero manual typing or HTTP client setup
Automatic request/response serialization
Built-in authentication handling
IDE autocomplete and IntelliSense support
Type Safety & Reliability
Catch integration errors at compile-time, not runtime. Generated clients provide complete type safety for all API interactions.
Compile-time error detection
Guaranteed API compatibility
Automatic API version updates
Validated request/response schemas
