Pro Feature

Bring Your Own Proxy (BYOP)

Connect your existing proxy subscriptions to AlterLab and use your own proxies while benefiting from our intelligent anti-bot technology.

Why Use BYOP?

Cost Optimization

Already have proxy subscriptions? Use them with AlterLab instead of paying twice. Your bandwidth, your proxies.

Provider Flexibility

Different providers excel at different sites. Mix and match providers for optimal coverage.

Geographic Control

Use proxies in specific countries or cities that your provider offers, even if AlterLab doesn't cover that region.

No Vendor Lock-in

Keep your existing relationships with proxy providers. Switch or combine as needed.

How Pricing Works with BYOP

When using your own proxy, AlterLab costs less since you're providing the proxy bandwidth. You still get our anti-bot technology, tier escalation, and content extraction at a reduced rate.

Supported Providers

Provider	Type	Required Credentials	Features
Bright Data	Residential, Datacenter, ISP	`username`, `password`, `zone`	Country/city targeting, session control
Oxylabs	Residential, Datacenter	`username`, `password`	Country targeting, sticky sessions
Smartproxy	Residential, Datacenter	`username`, `password`	Auto-rotation, country targeting
IPRoyal	Residential, Datacenter	`username`, `password`	Pay-as-you-go, country targeting
DataImpulse	Residential	`api_key`	Pay-per-GB, 195+ countries
Custom	Any HTTP/SOCKS5	`proxy_url`	Bring any proxy that supports standard protocols

Account Requirements

You need an active subscription with the proxy provider. AlterLab validates your credentials during setup and will show an error if your account is inactive or has insufficient balance.

How It Works

1. Request Arrives

When you make a scrape request, AlterLab checks if you have any BYOP integrations configured.

2. Proxy Selection

Based on your strategy (proactive or reactive), the domain's requirements, and integration priority, AlterLab selects the optimal proxy. BYOP integrations are preferred when available.

3. Intelligent Routing

Your request is routed through your proxy with AlterLab's anti-detection measures: TLS fingerprinting, header rotation, and stealth browser profiles.

4. Fallback Handling

If your proxy fails, AlterLab automatically escalates to higher tiers or falls back to AlterLab's proxy network (charged normally) to ensure request success.

Setup Guide

Step 1: Get Provider Credentials

Log into your proxy provider's dashboard and locate your API credentials. Different providers use different authentication methods:

Bright Data: Dashboard → Zones → Select Zone → Credentials
Oxylabs: Dashboard → Proxies → User Credentials
Smartproxy: Dashboard → Proxy Setup → Authentication
DataImpulse: Dashboard → API → API Key

Step 2: Add Integration via Dashboard

The easiest way to add a proxy integration is through the AlterLab dashboard:

Go to Dashboard → Integrations → Proxies
Click "Add Integration"
Select your proxy provider
Enter your credentials
Click "Test Connection" to verify
Save the integration

Step 3: Add Integration via API (Alternative)

You can also add integrations programmatically:

Python

import requests

# Create a Bright Data integration
response = requests.post(
    "https://api.alterlab.io/api/v1/proxies",
    headers={
        "Authorization": "Bearer YOUR_SESSION_TOKEN",
        "Content-Type": "application/json"
    },
    json={
        "provider": "brightdata",
        "name": "My Bright Data Residential",
        "credentials": {
            "username": "brd-customer-xxx-zone-residential",
            "password": "your_password"
        },
        "is_default": True
    }
)

print(response.json())

Step 4: Test Your Integration

Verify the integration works before using it in production:

Python

# Test the integration
response = requests.post(
    f"https://api.alterlab.io/api/v1/proxies/{integration_id}/test",
    headers={"Authorization": "Bearer YOUR_SESSION_TOKEN"},
    json={
        "test_url": "https://httpbin.org/ip",
        "timeout_seconds": 30
    }
)

result = response.json()
if result["success"]:
    print(f"Success! Proxy IP: {result['proxy_ip']}")
    print(f"Response time: {result['response_time_ms']}ms")
else:
    print(f"Failed: {result['error']}")

Per-Request Proxy Selection

Override your default proxy on individual requests using the advanced options:

Parameter	Description

use_system_proxy	Override BYOP default and force AlterLab system proxy for this request
proxy_country	Preferred proxy country code (e.g., US, DE, JP)

JSON

// Use a specific integration for this request
{
  "url": "https://geo-restricted-site.com",
  "advanced": {
    "use_own_proxy": true,
    "proxy_integration_id": "550e8400-e29b-41d4-a716-446655440000",
    "proxy_country": "DE"
  }
}

// Force AlterLab system proxy (bypass your default BYOP)
{
  "url": "https://example.com",
  "advanced": {
    "use_system_proxy": true
  }
}

Best Practices

1. Use Multiple Providers

Different proxy providers have different IP pools and success rates on different sites. Configure multiple integrations and let AlterLab automatically select the best one.

JSON

// Set priority to control selection order
{
  "integrations": [
    {"name": "BrightData Residential", "priority": 10},  // First choice
    {"name": "Oxylabs Datacenter", "priority": 5},       // Fallback
    {"name": "SmartProxy", "priority": 1}                // Last resort
  ]
}

2. Monitor Usage & Balance

Check your provider usage regularly to avoid running out of bandwidth mid-scrape. Set up alerts in your provider's dashboard for low balance warnings.

Poll /proxies/{id}/usage weekly
Set budget alerts in provider dashboards
Configure fallback to AlterLab proxies when balance is low

3. Test Before Production

Always test new integrations with the /testendpoint before using them in production scraping jobs.

4. Rotate Credentials Periodically

For security, rotate your proxy credentials every few months. Update them in AlterLab using the credentials update endpoint.

Credential Security

Your proxy credentials are encrypted at rest using AES-256 encryption. AlterLab never logs or exposes your credentials. However, you should still use dedicated credentials for AlterLab rather than your main account credentials.

Integration Limits

Maximum integrations per user: 10 total
Maximum per provider: 3 integrations (for different zones/configs)
Validation timeout: 30 seconds
Endpoints cache: Refreshed on demand or every 24 hours
