api-specification-extraction
Summary
Extract HTTP endpoint definitions, request/response schemas, and authentication mechanisms from webservice source code and map them into a formal API specification (OpenAPI 3.0). This skill is essential when integrating or documenting webservice components whose interfaces are defined in code rather than published specifications.
When to use
You have access to the source code of a webservice component (Python, configuration files, route definitions) and need to produce machine-readable API documentation (OpenAPI 3.0 format) that captures all HTTP endpoints, methods, URL patterns, parameter names, payload schemas, and authentication details. This is triggered when the webservice lacks published API documentation but serves as a dependency for other components (e.g., joblauncher webservice in MAGMa is called by the web application to trigger job calculations).
When NOT to use
- API specification is already published or available in OpenAPI/Swagger format — use direct specification import instead
- Webservice source code is unavailable or obfuscated — extraction requires readable source
- Endpoint behavior is dynamically generated or non-deterministic at runtime — static extraction will be incomplete or inaccurate
Inputs
- webservice source code repository (Python, configuration files, route definitions)
- function signatures and type hints from endpoint handlers
- serialization logic and data model definitions
Outputs
- OpenAPI 3.0 specification document (JSON or YAML)
- mapped HTTP endpoints with methods, URL patterns, and parameters
- request and response schemas with type definitions
- authentication mechanism documentation
How to apply
Clone the webservice repository and locate source files defining HTTP routes, endpoints, and request/response handlers (e.g., Python route definitions and function signatures). Systematically examine each endpoint to extract: (1) HTTP method and URL pattern, (2) query, path, and body parameters with their names and types from function signatures and type hints, (3) request and response payload structures by analyzing serialization logic and type annotations, (4) authentication and authorization mechanisms (e.g., API keys, headers). Map these extracted elements into an OpenAPI 3.0 document structure with proper schemas, parameter definitions, and response models. Validate the generated specification against the source code for structural correctness, parameter completeness, and schema accuracy by cross-referencing endpoint implementations.

Evaluation signals
- Generated OpenAPI specification validates against OpenAPI 3.0 JSON schema without structural errors
- All HTTP endpoints present in source code are represented in the specification with correct methods and URL patterns
- Request and response payload schemas match the serialization logic and type annotations observed in source code
- Parameter names, types, and locations (query/path/body) extracted from function signatures correspond exactly to actual endpoint implementations
- Authentication mechanisms (if present) are documented with correct header names and validation logic from source code
Limitations
- Extraction accuracy depends on code readability and consistent use of type hints; untyped or poorly structured code may yield incomplete specifications
- Dynamic endpoints generated at runtime or conditional route definitions may not be fully captured by static source analysis
- Implicit API contracts (e.g., undocumented headers, version-specific behavior) present in code comments but not type annotations may be missed
- The README does not provide detailed endpoint examples or authentication specification details, requiring deep source code inspection for completeness
