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 screenshot
`X-Oxylabs-Session-Id`	Reuse same IP across requests (any random string)
`X-Oxylabs-Geo-Location`	Target country (e.g., `Germany`, `United States`)
`x-oxylabs-force-headers: 1`	Enable custom header passthrough
`X-Oxylabs-Successful-Status-Codes`	Define custom success codes to prevent retries

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"

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
Avoid adding custom unblocking headers that may interfere with the AI
