## FAQ

### Why can I connect directly from China?

We use compliant enterprise-grade dedicated lines for China connectivity, ensuring stable and fast access for users in mainland China.

### What's the difference between HTTPS and HTTP?

* **HTTPS** (Recommended): Encrypted transmission, high data security
* **HTTP** (Alternative): Plain text transmission, use only temporarily when HTTPS issues occur

### How to check if network connection is normal?

You can test using the following commands:

```bash theme={null}
# Test API connection
curl -I https://api.apiyi.com

# Test DNS resolution
ping api.apiyi.com
```

If you receive normal responses, the network connection is fine.
