# PCB defect detection API

FastAPI + ONNX Runtime inference service for a YOLO11n PCB defect detector (static INT8, detection
head FP32), CPU inference on the free tier. Source, tests, CI and benchmarks: https://gitlab.com/michael.sucahyo/pcb-defect-optimization

```bash
curl -F "file=@board.jpg;type=image/jpeg" https://michaelandrew35-pcb-defect-api.hf.space/v1/predict
```

Endpoints: `POST /v1/predict`, `GET /v1/health`, `GET /v1/metrics`, `GET /v1/docs`.
Free Spaces sleep when idle; the first request after a pause waits for a cold start.
