# OpenBB Investment Analysis API

REST API wrapping OpenBB SDK, providing stock data, sentiment analysis, technical indicators, quantitative risk metrics, macro data, market data (ETF/index/crypto/forex/options), and rule-based investment analysis for US and Swedish markets. Designed to be called by OpenClaw (or any AI assistant) -- the API returns structured data, all LLM reasoning happens on the caller side.

## API Keys

### Required: None

The core functionality uses **yfinance** (free, no API key). The API works without any keys configured.

## Rule Engine

The portfolio analysis endpoint uses a rule-based engine (no LLM) that scores each holding on four signals:

| Signal | BUY_MORE (+1) | HOLD (0) | SELL (-1) |
|--------|---------------|----------|-----------|
| Price vs analyst target | >15% upside | -10% to +15% | >10% downside |
| PE ratio | < 15 | 15 - 35 | > 35 or negative |
| Revenue growth | > 10% YoY | 0 - 10% | Negative |
| P&L vs cost basis | Loss > 20% | -20% to +50% | Profit > 50% |

Scores are summed. Total >= 2 = BUY_MORE, <= -2 = SELL, otherwise HOLD. Confidence is HIGH/MEDIUM/LOW based on how many signals agree.

## Configuration

All settings are configurable via environment variables with the `INVEST_API_` prefix:

| Variable | Default | Description |

| `INVEST_API_HOST` | `0.0.0.0` | Server bind address |

## Running Tests

```bash
conda activate openbb-invest-api
python -m pytest tests/ -v
```

## Swedish Stocks

Swedish stocks are supported via the `.ST` suffix (Stockholm exchange):
- `VOLV-B.ST` (Volvo)
- `ERIC-B.ST` (Ericsson)
- `HM-B.ST` (H&M)
- `SEB-A.ST` (SEB)
- `SAND.ST` (Sandvik)

## Integration with OpenClaw

This API is designed to be called by OpenClaw as an MCP tool or HTTP data source. OpenClaw sends requests to this API to fetch structured stock data and rule-based analysis, then uses its LLM to generate natural language investment advice.

Example OpenClaw workflow:
1. User asks: "Should I buy more AAPL?"
2. OpenClaw calls `GET /api/v1/stock/AAPL/summary` for fundamental data
3. OpenClaw calls `GET /api/v1/stock/AAPL/sentiment` for news/analyst sentiment
4. OpenClaw calls `GET /api/v1/stock/AAPL/technical` for technical signals
5. OpenClaw calls `GET /api/v1/stock/AAPL/performance` for risk metrics (Sharpe, volatility)
6. OpenClaw calls `GET /api/v1/stock/AAPL/sec-insider` for insider trading activity
7. OpenClaw calls `GET /api/v1/macro/overview` for market context
8. OpenClaw calls `POST /api/v1/portfolio/analyze` with user's holdings
9. OpenClaw's LLM synthesizes all structured data into a personalized recommendation
