## Local DB System

The platform uses a **dual-layer caching system**:

1. **SQLite Database** (`/data/platform.db`) - Primary store for integrations and tools
2. **JSON Backup** (`/data/composio_cache.json`) - Raw Composio API response backup

### How it works:

1. **Startup**: Tries to fetch from Composio API
2. **If API succeeds**: Saves to SQLite + JSON backup
3. **If API fails**: Loads from JSON backup → seeds SQLite
4. **If no cache**: Uses minimal fallback definitions (5 integrations)

### Cache TTL: 24 hours (configurable via `CACHE_TTL`)

## Tool Calls Quota

**Good news**: Fetching tools via `GET /api/v3.1/toolkits` and `GET /api/v3.1/tools` **does NOT consume your 20,000 free tool calls**. Only `POST /api/v3.1/tools/execute/{slug}` counts as a tool call.

## Build & Run

### Option 1: Docker (Recommended for HF Spaces)

```bash
cd /home/runner/workspace/platform

# Set your Composio API key
export COMPOSIO_API_KEY=sk_your_key_here

# Build
docker build -t platform .

# Run
docker run -p 7860:7860 \
  -v $(pwd)/data:/data \
  -e COMPOSIO_API_KEY=$COMPOSIO_API_KEY \
  platform
```

### Option 2: Direct (Development)

```bash
cd /home/runner/workspace/platform

# Build frontend
cd frontend && npm install && npm run build && cd ..

# Install backend deps
cd backend && pip install -r requirements.txt && cd ..

# Set env vars
export COMPOSIO_API_KEY=sk_your_key_here
export DATA_DIR=$(pwd)/data

# Initialize and run
python -c "from backend.database import init_db; init_db()"
python backend/integrations/registry.py  # Syncs tools
cd backend && uvicorn main:app --reload --port 7860
```

## Test

```bash
# After starting the server:
cd /home/runner/workspace/platform
chmod +x test.sh
./test.sh
```

## Hugging Face Spaces Deployment

1. Create a new Docker Space on HF
2. Push these files to the repo:
   ```
   Dockerfile
   entrypoint.sh
   backend/
   frontend/
   .env.example
   ```
3. Add `COMPOSIO_API_KEY` as a Space secret
4. The Space will auto-build and start on port 7860
