## Server Purchasing Recommendations

### International Server Recommendations

If you're using international servers to call APIYI services, we recommend:

<Tip>
  **Recommended Choice**: US West (Los Angeles, San Jose, Seattle, etc.) data center servers

  * **Geographic proximity**: Same region as our servers, lowest latency
  * **Optimized network routing**: Best routing between same region
  * **Cost-effective**: US West data centers offer reasonable pricing
</Tip>

If you're looking for a reliable VPS provider, consider the same provider we use:

<Card title="BandwagonHost VPS" icon="server" href="https://bandwagonhost.com/aff.php?aff=79264">
  **BandwagonHost** - Reputable VPS Provider

  * ✅ China-optimized premium network (CN2 GIA, CN2, etc.)
  * ✅ Multiple US West data centers (Los Angeles, San Jose, etc.)
  * ✅ Stable, reliable, cost-effective
  * ✅ Suitable for both domestic and international users

### Mainland China Servers

<Info>
  **Mainland China servers work great too!**

  Thanks to our China-optimized premium network, even if your server is located in mainland China, accessing APIYI has normal latency and speed with no network concerns.
</Info>

**Suitable scenarios**:

* Applications deployed on domestic cloud providers (Alibaba Cloud, Tencent Cloud, Huawei Cloud, etc.)
* Users primarily in mainland China
* Need to meet domestic compliance requirements

## How to Test Network Latency?

Before choosing a server, we recommend testing network latency from your server to APIYI.

### Method 1: Ping Test

```bash theme={null}
# Test latency (ICMP)
ping api.apiyi.com
```

**Reference latency**:

* **Mainland China**: Usually 50-150ms (premium network optimized)
* **US West region**: Usually 5-30ms (same region)
* **Europe/Asia-Pacific**: Usually 150-300ms (cross-region)

### Method 2: cURL Latency Test

```bash theme={null}
# Single HTTP latency test
curl -o /dev/null -s -w "Connect time: %{time_connect}s\nTotal time: %{time_total}s\n" https://api.apiyi.com

# Multiple tests for average (more accurate)
for i in {1..10}; do
  curl -o /dev/null -s -w "Test $i - Total time: %{time_total}s\n" https://api.apiyi.com
done
```

### Method 3: Actual API Call Test

```bash theme={null}
# Test actual API call latency
time curl -X POST https://api.apiyi.com/v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-4o-mini",
    "messages": [{"role": "user", "content": "Hello"}],
    "max_tokens": 10
  }'
```

<Tip>
  **Optimization suggestion**: If latency is high (over 500ms), consider:

  * Switching to a US West data center server
  * Using CDN or proxy acceleration
  * Contacting customer service for network optimization solutions
</Tip>

## Network Optimization Recommendations

### For High Latency Scenarios

If your server has high latency, try these optimization solutions:

<Steps>
  <Step title="Use Connection Pooling">
    Reuse HTTP connections to avoid frequent new connection overhead
  </Step>

  <Step title="Enable HTTP/2 or HTTP/3">
    Leverage multiplexing features to improve concurrent request efficiency
  </Step>

  <Step title="Batch Requests">
    Combine multiple small requests into batch requests to reduce network round trips
  </Step>

  <Step title="Async Calls">
    Use asynchronous API calls to avoid blocking waits
  </Step>

  <Step title="Local Caching">
    Cache repeated request results to reduce API call frequency
  </Step>
</Steps>

### For Large Image Transfers

If you frequently transfer large images (e.g., image generation, image recognition), we recommend:

<CardGroup cols={2}>
  <Card title="Use URL Parameters" icon="link">
    Prefer image URLs over Base64 encoding

    Reduces request body size, improves transfer efficiency
  </Card>

  <Card title="Compress Images" icon="file-archive">
    Appropriately compress image quality before upload

    Reduce file size while maintaining quality
  </Card>

## Frequently Asked Questions

<AccordionGroup>
  <Accordion title="Why choose US West instead of other regions?">
    **Main reasons**:

    1. **Premium network optimization**: US West is the main exit point for China-bound premium networks, providing optimal routing for mainland China users
    2. **International hub**: Los Angeles is a major international network hub connecting Asia-Pacific, Europe, North America, etc.
    3. **Cost advantage**: US West data centers have relatively low bandwidth costs and high cost-effectiveness
    4. **Service stability**: Providers like BandwagonHost have extensive US West operation experience and good stability
  </Accordion>

  <Accordion title="Will accessing APIYI from mainland China be slow?">
    **No!**

    We use BandwagonHost's **China-optimized premium network** (CN2 GIA, etc.), specially optimized for mainland China users.
