# SQuADDS ML Inference API

Auto-generated deployment bundle for serving ML_qubit_design models with a FastAPI app.

## Live URLs

- Space repo: https://huggingface.co/spaces/SQuADDS/squadds-ml-inference-api
- Space host: https://squadds-squadds-ml-inference-api.hf.space

## Endpoints

- `GET /health`
- `GET /models`
- `POST /predict`

## Quickstart

List models:

```bash
curl https://squadds-squadds-ml-inference-api.hf.space/models
```

## Included Models

Run a sample prediction:

```bash
curl -X POST \
  https://squadds-squadds-ml-inference-api.hf.space/predict \
  -H 'Content-Type: application/json' \
  -d '{"model_id": "transmon_cross_hamiltonian_inverse", "inputs": {"qubit_frequency_GHz": 4.85, "anharmonicity_MHz": -205.0}, "options": {"include_scaled_outputs": false}}'
```

Sample response:
