Oxylabs Web Unblocker
AI-powered proxy solution that automatically manages fingerprinting, headers, retries, and JavaScript rendering.
Endpoint
https://unblock.oxylabs.io:60000
Authentication
HTTP Basic Auth via proxy credentials:
curl -k -x "https://unblock.oxylabs.io:60000" \
-U "$OXYLABS_USERNAME:$OXYLABS_PASSWORD" \
"https://example.com"
Quick Start
Basic request:
curl -k -x "https://unblock.oxylabs.io:60000" \
-U "$OXYLABS_USERNAME:$OXYLABS_PASSWORD" \
"https://ip.oxylabs.io/headers"
With JavaScript rendering:
curl -k -x "https://unblock.oxylabs.io:60000" \
-U "$OXYLABS_USERNAME:$OXYLABS_PASSWORD" \
-H "x-oxylabs-render: html" \
"https://example.com/spa-page"
Headers
| Header | Description |
|---|
x-oxylabs-render | html for rendered HTML, png for raw PNG bytes; empty value disables automatic forced rendering |
X-Oxylabs-Session-Id | Reuse same IP across requests (any random string) |
X-Oxylabs-Geo-Location | Target country, city/state, ZIP/postcode, or coordinates |
x-oxylabs-force-headers: 1 | Enable custom header passthrough |
x-oxylabs-force-cookies: 1 | Enable custom cookie passthrough |
X-Oxylabs-Successful-Status-Codes | Define custom success codes to prevent retries |
x-oxylabs-browser-instructions | JSON-escaped browser actions; requires x-oxylabs-render: html |
Session Persistence
Reuse the same IP across multiple requests:
curl -k -x "https://unblock.oxylabs.io:60000" \
-U "$OXYLABS_USERNAME:$OXYLABS_PASSWORD" \
-H "X-Oxylabs-Session-Id: my-session-123" \
"https://example.com/page1"
Geo-Location Targeting
curl -k -x "https://unblock.oxylabs.io:60000" \
-U "$OXYLABS_USERNAME:$OXYLABS_PASSWORD" \
-H "X-Oxylabs-Geo-Location: Germany" \
"https://example.com"
Use values such as Germany, 90210, California,United States, New York,New York,United States, or lat: 40.7128, lng: -74.0060, rad: 50.
Use normal HTTP methods and request bodies through the proxy; Web Unblocker supports both GET and POST.
When to Use Web Unblocker vs Regular Proxies
| Scenario | Use |
|---|
| Sites with anti-bot protection | Web Unblocker |
| CAPTCHAs, fingerprint detection | Web Unblocker |
| JavaScript-heavy SPAs | Web Unblocker with x-oxylabs-render: html |
| Simple requests, no protection | Regular Proxies |
| High volume, price sensitive | Regular Proxies |
Key Guidelines
- Always use
-k flag (or disable SSL verification) - the proxy uses its own certificates
- Add
x-oxylabs-render: html if experiencing empty content or low success rates; set client timeouts near 180 seconds for rendered requests
- Check
X-Oxylabs-Final-Url in response headers when redirects matter
- Avoid adding custom unblocking headers that may interfere with the AI
- Browser instruction header values must be JSON-escaped and compact; pair them with
x-oxylabs-render: html
