Rest Api Image Generation Integration

via “rest api with request/response serialization”

Stable Diffusion web UI

Unique: Implements FastAPI-based REST API with automatic request validation via Pydantic models, supporting both synchronous and asynchronous generation with optional job queuing. Serializes images as base64-encoded PNG in JSON responses, enabling seamless integration with web frameworks. Includes optional API key authentication and CORS support for cross-origin requests.

vs others: More flexible than cloud APIs (local deployment, no rate limits, custom models) and simpler than gRPC (standard HTTP, no special client libraries required)
