## Important Guidelines

### Cryptos: Use IDs | Stocks: Use Tickers
- **Cryptocurrencies**: Always use **Coin IDs** (slugs) instead of ticker symbols (e.g., `bitcoin`, `BTC`).
- **Stocks**: Always use **Ticker Symbols** (e.g., `AAPL`, `Apple`).

Use `search_coins.js` if you are unsure of the correct ID.

### Authentication
Authentication is handled **automatically** by the internal `api_client.js`. Here is how it works simply:

- **Endpoint**: `GET https://api.igent.net/api/token`
- **Mechanism**:
    1.  **Automatic Retrieval**: The first time you use a tool, it asks the server for a temporary session token.
    2.  **Local Storage**: This token is stored in a hidden `.token` file locally so it can be reused for subsequent requests.
    3.  **Automatic Headers**: The client automatically includes this token in every request to prove you are authorized.
    4.  **Auto-Refresh**: If a token expires, the client automatically fetches a new one without you needing to do anything.

No manual API keys or configuration are required.

### Rate Limiting
While the system is robust, please avoid burst requests (more than 30 per minute) to maintain service stability for all users.

### Agent Integration
This skill is fully compatible with OpenClaw and other agents using the **AgentSkills** standard. Execute scripts directly from the `scripts/` directory.
