# Panacea -- Satellite Collision Avoidance API
FastAPI backend for the Panacea satellite collision avoidance system.
## Endpoints
- `GET /api/health` -- Health check, lists loaded models
- `POST /api/predict-conjunction` -- Run inference on a CDM sequence
- `GET /api/model-comparison` -- Pre-computed model comparison results
- `GET /api/experiment-results` -- Staleness experiment results
- `POST /api/bulk-screen` -- Screen TLE pairs for potential conjunctions
## Models
Three models are loaded at startup from [DTanzillo/panacea-models](https://huggingface.co/DTanzillo/panacea-models):
1. **Baseline** -- Orbital shell density prior (AUC-PR: 0.061)
2. **XGBoost** -- Classical ML on engineered CDM features (AUC-PR: 0.988)
3. **PI-TFT** -- Physics-Informed Temporal Fusion Transformer (AUC-PR: 0.511)
Built for AIPI 540 (Duke University).
