# Introduction
QFEX provides a unified interface for trading and market data via:
* **CLI**: JSON-only command-line access for human operators and AI agents.
* **WebSocket**: Low latency, real-time market data and order entry.
If you want to integrate QFEX into an agentic trading workflow without managing WebSocket connections directly, use the [QFEX CLI](/api-reference/cli).
## Authentication & API Keys
All API calls must be authenticated with an **API Key**. You can create and manage your keys from your QFEX dashboard:
1. Sign in at [qfex.com](https://qfex.com) and select your profile in the bottom right corner.
2. Navigate to **Developer Settings** via the carousel.
3. Click **Generate public and secret API Keys**.
4. Ensure you have 2FA Enabled.
5. Provide a descriptive name, and confirm.
6. **Copy** the generated key and store it securely — it will only be shown once.
